1.1 A Brief History of Neuropsychology 30 Day MCAT CHAPTER 1 - BIOLOGY & BEHAVIOUR Franz Gall: (1758 – 1828). Phrenology Doctrine of Phrenology: The idea was that if a particular trait was well- developed, then the part of the brain responsible for that trait would Pierre Flourens: (1794 – 1867). expand. Functions of major sections of the brain. Used extirpation to study parts of brain. (Was found to be false, it did generate serious research on brain functions) William James: (1842 – 1910). Functionalism: How mental processes Father of American Psychology: William James help individuals adapt to their environment. Functionalism: A system of though in psychology that studied how mental processes help individuals adapt to their environments. John Dewey: (1859 – 1952). Functionalism Broca's Area: Specific part in the left side of the brain named after him after he found that a man who’d been unable to talk was unable to do Paul Broca: (1824 – 1880). Studied so because of a lesion the area. people with legions in specific regions of brain. Broca’s Area: Speech Existence of Synapses: Discovered by Sir Charles Sherrington. production. However, he thought that synaptic transmission was an electrical Hermann von Helmholtz: (1821 – 1894). process, but we now know that it is primarily a chemical process. Speed of impulse. Made psychology a science. "Mind Pioneers Unveiled Brains' Evolution." Explanation: Mind: Represents the focus on studying the brain's functions related to Sir Charles Sherrington: (1857 – 1952). the mind. Synapses Pioneers: Refers to the early researchers and scientists who contributed to the field. Sigmund Freud: (1856 – 1939). Unveiled: Signifies the revelation of insights about brain function. Psychoanalytic perspective. Brains' Evolution: Highlights the progression and development of knowledge about the brain over time. 1.2 Organization of the Human Nervous System 30 Day MCAT CHAPTER 1 - BIOLOGY & BEHAVIOUR Neurons: Sensory: Afferent, receptors > spinal cord Interneurons: Between other neurons. Mainly CNS. Motor: Efferent, CNS > muscles & glands Reflex Arcs: Interneurons in spinal cord relay info to the source of stimuli while simultaneously routing it to the brain. Central Nervous System (CNS): Brain and spinal cord. Peripheral Nervous System (PNS): Nervous tissue and fibers outside CNS Somatic: Voluntary Autonomic: Sympathetic = F/F, parasympathetic = R/D. 1.3 Organization of the Brain 30 Day MCAT CHAPTER 1 - BIOLOGY & BEHAVIOUR Hindbrain: Cerebellum, medulla oblongata, Anatomical Subdivisions of the reticular formation. Human Brain: Midbrain: Inferior and superior colliculi. There are 3 main subdivisions: 1. Forebrain Forebrain: Thalamus, hypothalamus, basal 2. Midbrain ganglia, limbic system, cerebral cortex. 3. Hindbrain Methods of Study: Electroencephalography Midbrain and hindbrain comprise (EEG). Regional cerebral blood flow. the brainstem and is associated with functions of basic survival Forebrain developed later and is associated with more complex functioning "Big Brains In Humans Have Many Grooves." Each initial letter corresponds to a major part of the brain: Big - Brainstem (Includes pons and medulla) Brains - Basal Ganglia (Motor control) The Meninges: Thick sheath of connective In - Internal Capsule (White matter tract) Humans - Hypothalamus (Homeostasis) tissue with the following functions: Have - Hippocampus (Memory) Help protect the brain Many - Meninges (Protective layers) keep it anchored within the skull Grooves - Gyri (Raised folds of the brain's surface) Resorb cerebrospinal fluid 1.4 Parts of the Forebrain 30 Day MCAT CHAPTER 1 - BIOLOGY & BEHAVIOUR Thalamus: Relay station for sensory information. Hypothalamus: Homeostasis & the 4 F’s. Integrates with endocrine system. Hypothalamus > hypophyseal portal > anterior pituitary Basal Ganglia: Smooths movements and helps postural stability. Limbic System: Septal Nuclei: Pleasure and addiction. Amygdala: Fear and aggression. Hippocampus: Emotion and memory. Cerebral Cortex: Four lobes 1. Frontal: Executive function, impulse control, speech, motor. 2. Parietal: Touch, pressure, temp, pain, spatial processing. 3. Occipital: Visual 4. Temporal: Sound, speech perception, memory, emotion. Cerebral Hemispheres: Left is analytic, language, logic, math. Usually dominant Right is intuition, creativity, spatial processing. 1.5 Influences on Behavior 30 Day MCAT CHAPTER 1 - BIOLOGY & BEHAVIOUR Neurotransmitters: Released by neurons to carry a signal. Acetylcholine: Used by somatic nervous system to move muscles. Also used by the parasympathetic and CNS. Dopamine: Maintains smooth movements and steady posture. Endorphins & Natural pain killers. Enkephalins: Epinephrine & Maintain wakefulness and mediate F/F responses. Norepinephrine: Epinephrine tends to act as a hormone, norepinephrine a neurotransmitter. g-aminobutyric Inhibitory neurotransmitters. Act as brain Acid (GABA): “stabilizers”. Glycine serves a similar function. Glutamate: Acts as an excitatory neurotransmitter. Serotonin: Modulates mood, sleep, eating, and dreaming. The endocrine system is tied to the nervous system through the hypothalamus and the anterior pituitary, and a few other hormones: Cortisol: Stress hormone released by the adrenal cortex. Testosterone & Mediate libido. Testosterone also aggressive Estrogen: behavior. Both are produced in gonads, released by adrenal cortex. nature heredity, or the influence of inherited characteristics on behavior Epinephrine & Released by adrenal medulla and cause physiological nurture Norepinephrine: changes associated with the sympathetic nervous system. influence of environment and physical surroundings on behavior 1.6 Development 30 Day MCAT CHAPTER 1 - BIOLOGY & BEHAVIOUR The nervous system develops through neurulation, in which the notochord stimulates overlying ectoderm to fold over, creating a neural tube topped with neural crest cells Neural Tube: Becomes the CNS Neural Crest Cells: Spread out throughout the body, differentiating into many different tissues. Primitive Reflexes: Exist in infants and should disappear with age. Rooting Reflex: Turns head toward stimulus. Moro Reflex: Extends arms, response to falling sensation. Babinski Reflex: Big toe is extended and other toes fan out in response to brushing on sole of foot. Grasping Reflex: Grabs anything put into hands. fetal nutrition Developmental Milestones Gross and fine motor abilities progress head to toe and core to periphery Social skills shift from parent-oriented to other-oriented Language skills become increasingly complex neurulation: development of the embryonic nervous system in which the notochord stimulates overlying ectoderm to fold over, creating a neural tube topped with neural crest cells 2.1 Sensation vs Perception 30 Day MCAT CHAPTER 2 - SENSATION AND PERCEPTION Sensory Receptors: Sensory nerves that respond to stimuli. Sensory Ganglia: Collection of cell bodies outside the CNS. Projection Areas: Areas in the brain that analyze sensory input. Absolute Threshold: The min of stimulus energy that will activate a sensory system. Threshold of The minimum stimulus energy that will create a Conscious Perception: signal large enough in size and long enough in duration to be brought into awareness. Difference Threshold: The min difference in magnitude between two stimuli before one can perceive this difference. Weber’s Law: Just Noticeable Difference (JND) for a stimulus is proportional to the magnitude of the stimulus. Signal Detection Refers to the effects of nonsensory factors, such Theory: as experiences, motives, and expectations on perception of stimuli. Accounts for response bias. Adaptation: Refers to a or in sensitivity to a stimulus. 2.2 Vision 30 Day MCAT CHAPTER 2 - SENSATION AND PERCEPTION Cornea: Gathers and filters incoming light. Iris: Controls size of pupil. Colored part of eye. Divides front of the eye into the anterior & posterior chamber. It contains 2 muscles, the dilator and constrictor pupillae. Lens: Refracts incoming light to focus it on the retina. Aqueous Produced by the ciliary body. Nourishes the eye and gives Humor: the eye its shape. Drains through the canal of Schlemm. Retina: Rods: Detect light / dark. Contain rhodopsin. Cones: Color. Short / medium / long. Cones are in the fovea, which is part of the macula. Pathway from retina: Rods/Cones bipolar cells ganglion cells optic nerve Retinal Disparity: Space between eyes; allows for binocular vision and depth. Horizontal & Integrates signals from ganglion cells and performs edge- Amacrine Cells: sharpening. Support: Vitreous on inside. Sclera and choroid on outside.

High spatial resolution. 2.3 Hearing and Vestibular Sense 30 Day MCAT CHAPTER 2 - SENSATION AND PERCEPTION Outer Ear: Pinna (auricle), external auditory canal, tympanic membrane. Middle Ear: Connected to nasal cavity by Eustachian tube. Ossicles: Acronym MIS and HAS. Malleus: Hammer Incus: Anvil Stapes: Stirrup. Footplate of stapes rests in the oval window of cochlea. Inner Ear: Bony Labyrinth: Filled with perilymph. Membranous Labyrinth: Filled with endolymph. Membranous labyrinth consists of cochlea (sound), utricle & saccule (linear acceleration) and semicircular canals (rotational acceleration & balance). Projection Areas: Superior Olive: Localizes sound. Located in brain stem. Inferior Colliculus: Startle reflex. Also used by both eyes help transmit and amplify the vibrations and ears in the vestibulo-ocular reflex which keeps the from the tympanic membrane to the inner ear eyes fixed on a single point as the head rotates. The inner ear sits within a bony labyrinth and contains - cochlea - vestibule - semicircular canal 2.4 Other Senses 30 Day MCAT CHAPTER 2 - SENSATION AND PERCEPTION Smell: The detection of volatile or aerosolized chemicals by the olfactory chemoreceptors (olfactory nerves) in the olfactory epithelium. Smell info bypasses the thalamus. Pheromones: Chemicals given off by animals that have an effect on social foraging, and sexual behavior. Taste: The detection of dissolved compounds by taste buds in papillae. Sweet/sour/salty/bitter/umamai. Somatosensation: Refers to the four touch modalities: Pressure, vibration, pain, temperature. Two-Point Threshold: Minimum distance necessary between 2 points of stimulation on the skin such that the points will be felt as two distinct stimuli. Physiological Zero: The normal temp of skin to which objects are compared to. Nociceptors: Pain reception. Gate theory of pain. JND for pain. Kinesthetic Sense: Proprioception 2.5 Object Recognition 30 Day MCAT CHAPTER 2 - SENSATION AND PERCEPTION Top-Down The recognition of an object by memories and expectations. Processing: Little attention to detail. Uses background knowledge. Bottom-Up Details ® whole. Recognition of objects by feature Processing: detection. Not influenced by background knowledge. Gestalt Proximity, similarity, continuity, closure. All are governed by Principles: the Law of Prägnanz. top-down (conceptually driven processing) gestalt principles refers to recognition of objects by memories and expectations with little attention to detail bottom-up (data driven processing) refers to recognition of objects by parallel processing and feature detection two major theories of psychological processing 3.1 Learning 30 Day MCAT CHAPTER 3 - LEARNING AND MEMORY Habituation: Becoming used to a stimulus. Dishabituation: When a 2nd stimulus intervenes causing a resensitization of the original stimulus. Associative Learning: Pairing together stimuli / responses or behaviors / consequences. Operant Conditioning: Behavior is changed through the use of consequences. Reinforcement: Increases likelihood of behavior. Punishment: Decreases likelihood of behavior. Schedule: The schedule of reinforcement can be based on an amount of time or a ratio of behavior / reward, and can be either fixed or variable. Positive Response: Adding something. Negative Response: Removing something. Extinction: When a previously reinforced behavior is no longer reinforced, it goes extinct. Shaping: In operant conditioning, shaping is a when behavior that is closer and closer to the target behavior is reinforced. Classical Conditioning: With repetition, a neutral stimulus becomes a conditioned stimulus that produces a conditioned response. Observational Learning The acquisition of behavior by watching others. or Modeling: 3.2 Memory 30 Day MCAT CHAPTER 3 - LEARNING AND MEMORY Encoding: The process of putting new info into memory. It can be automatic or effortful. Semantic encoding is stronger than both acoustic and visual encoding. Sensory & Short Term Transient and based on neurotransmitter activity. Memory: Working Memory: Requires STM, attention, and executive function to manipulate information. Long Term Memory: Requires elaborate rehearsal and is the result of increased neuronal connectivity. Explicit (declarative) Memory: Accounts for memories that we must consciously recall with effort and focus. Implicit (nondeclaritive) Memory: Accounts for acquired skills and conditioned responses to circumstances and stimuli. Semantic Networks: Stores facts. Concepts are linked together based on similar meaning. Certain triggers will activate associated memories. Retrieval: Recognition of info is stronger than recall. Retrieval is often based on priming interconnected nodes of the semantic network. Diseases: Alzheimers: Degenerative brain disorder linked to a loss of acetylcholine in neurons that link to hippocampus. Causes dementia and memory loss. Korsakoff’s Syndrome: Memory loss caused by thiamine deficiency in the brain. Causes retrograde amnesia and anterograde amnesia. Another symptom is confabulation, Mnemonic for Semantic Mnemonic for Working the fabrication of vivid but fake memories. Networks: "FACTS" Memory: "WAWE" Agnosia: Loss of ability to recognize objects, people, or sounds. Usually caused by physical damage to brain. F: Facts stored. W: Working memory. A: Associated memories. Interference: Retroactive Interference: New memories make you forget C: Concepts linked. A: Attention needed. old memories. T: Triggers activate. W: Requires STM. Proactive Interference: Old memories interfere with learning S: Similar meaning. E: Executive function. new memories. 3.3 Neurobiology of Learning and Memory 30 Day MCAT CHAPTER 3 - LEARNING AND MEMORY Neuroplasticity: Neural Circuits: Memory formation and learning involve intricate Neuroplasticity, also known as brain plasticity or neural plasticity, networks of interconnected neurons known as neural circuits. These refers to the brain's ability to reorganize and adapt by forming circuits facilitate the storage, retrieval, and consolidation of new neural connections throughout life. It involves the ability of memories. neurons to modify their structure and function in response to Synaptic Pruning: This is the process by which the brain eliminates learning, experience, and environmental changes. Neuroplasticity weaker or unused synaptic connections, allowing for more efficient underlies learning and memory processes, allowing the brain to neural communication and information processing. adapt to new information, recover from injuries, and compensate for damage. Consolidation: After initial learning, memories go through a process called consolidation, during which they become more stable and Two Types of Brain Plasticity: resistant to interference. This process involves the strengthening of Structural Plasticity: This refers to the physical changes in the neural connections. brain's neural pathways and synapses. It involves the growth of new dendritic branches, the formation of new synapses, and Hippocampus: The hippocampus is a brain region crucial for the even the elimination of existing synapses in response to formation of new memories and spatial navigation. It's often learning experiences. Structural plasticity allows the brain to implicated in episodic and declarative memory. physically rewire itself based on learning and memory Amygdala: The amygdala plays a key role in processing emotions, demands. particularly fear-related responses. It's also involved in the Functional Plasticity: This type of plasticity involves changes emotional aspects of memory consolidation. in the function of existing neural pathways. It often occurs in Encoding, Storage, Retrieval: These are the three main stages of response to damage or injury to specific brain regions. Other memory processing. Encoding involves the initial acquisition of areas of the brain may take over the functions of the information, storage involves maintaining the information over time, damaged regions, allowing for compensation and recovery. and retrieval involves bringing the stored information back into Functional plasticity is particularly important in cases of brain conscious awareness. injury or stroke. Neurotransmitters and Memory: Various neurotransmitters, such Long-Term Potentiation (LTP): as glutamate, acetylcholine, and dopamine, play critical roles in Long-term potentiation (LTP) is a phenomenon in which the facilitating communication between neurons and are essential for strength of synaptic connections between neurons is increased memory processes. after repeated and persistent stimulation. It is considered one of the cellular mechanisms underlying learning and memory. During LTP, there is an enhancement in the ability of one neuron to influence the firing of another neuron, leading to improved signal transmission and communication between neurons. LTP is often studied in the context of hippocampal synapses and is thought to be a crucial process for the formation and storage of memories. 4.1 Cognition 30 Day MCAT CHAPTER 4 - COGNITION, CONSCIOUSNESS, AND LANGUAGE Information The brain encodes, stores, and retrieves info much like a Processing Model: computer. Piaget’s Stages: Involve schemas and assimilation vs. accommodation. Sensorimotor: 0 2 yrs. Child manipulates the environment to meet physical needs through circular reactions.

Instincts: Innate, fixed patterns of behavior in response to stimuli. Instinct Theory: People perform certain behaviors because of their evolutionarily programmed instincts. Arousal: The state of being awake and reactive to stimuli. Optimal Arousal Optimal performance requires optimal arousal. Arousal Theory: levels that are too or too will impede performance Drives: Internal states of tension that beget particular behaviors focused on goals. Primary drives: related to biological processes. Secondary drives: stem from learning. Drive Reduction Motivation arises from the desire to eliminate drives, Theory: which create uncomfortable internal states. Maslow’s Hierarchy of Physiological, safety and security, love and belonging, Needs: self-esteem, and self-actualization. Higher needs only produce drives once lower needs are met. Opponent-Process Explains motivation for drug use: as drug use increases, Theory: the body counteracts its effects, leading to tolerance and uncomfortable withdrawal symptoms. Self-Actualization: Full realization of one’s talents and potential. House Money Effect: After a prior gain, people become more open to assuming risk since the new money is not treated as one's own. Self-Determination Emphasizes 3 universal needs: autonomy, competence, Theory: and relatedness. Gambler’s Fallacy: If something happens more frequently than normal, it will happen less frequently in the future, or vice versa. Incentive Theory: Explains motivation as the desire to pursue rewards and Prisoner’s Dilemma: Two people act out of their own self-interest, but if avoid punishments. they had cooperated, the result would have been even better. Expectancy-Value The amount of motivation for a task is based on the Theory: expectation of success and the value of that success. 5.2 Emotion 30 Day MCAT CHAPTER 5 - MOTIVATION, EMOTION AND STRESS Emotion: A state of mind, or feeling, that is subjectively experienced based on circumstances, mood, and relationships Three Components of Cognitive: Subjective Emotion: Physiological: Changes in autonomic nervous system Behavioral: Facial expressions and body language 7 Universal Emotions: Happiness, sadness, contempt, surprise, fear, disgust and anger James-Lange Theory: Behavioral and physiological actions lead to emotions. Ex: Power posing. Cannon-Bard Theory: Emotional and physiological responses to a stimulus occur simultaneously. They arise from separate and independent areas of the brain. Schacter-Singer Theory: Two-factor theory of emotion. Physiological arousal and interpretation of context or “cognitive label” limbic system lead to emotion. Limbic System: Concerned with instincts and mood. See appendix for full diagram. 5.3 Stress 30 Day MCAT CHAPTER 5 - MOTIVATION, EMOTION AND STRESS Stress: The physiological and cognitive response to challenges or life changes. Stress Appraisal: Primary Appraisal: Classifying a potential stressor as irrelevant, benign-positive, or stressful. Secondary Appraisal: Evaluating if the organism can cope with the stress. Stressors: Anything that leads to a stress response. Can lead to distress or eustress. General Adaptation Specific stressors do not have specific responses, Syndrome: they all generate the same general physical stress response. 3 stages of stress: Alarm, resistance, exhaustion. These involve both the sympathetic nervous system and the endocrine system; release of ACTH leads to cortisol. Eustress Distress a form of stress having the type of stress we a beneficial effect on are referring too when health, motivation, we say stress.

Role-Taking 6.3 Personality 30 Day MCAT CHAPTER 6 - IDENTITY AND PERSONALITY Psychoanalytic Personality results from unconscious urges & desires. Perspective: Freud, Jung, Adler, and Horney. Freud’s Theory: Id: Base urges of survival and reproduction. Superego: The idealist and perfectionist. Ego: Mediator between the two and the conscious mind. The ego uses defense mechanisms to stress. All three operate, at least in part, in the unconscious. Jung: Collective unconscious links all humans together. Personality is influenced by archetypes. Adler & Horney: Unconscious is motivated by social urges. Humanistic Emphasizes the internal feelings of healthy individuals as Perspective: they strive for happiness and self-realization. Maslow’s hierarchy of needs and Rogers’s unconditional positive regard flow from the humanistic view of personality. Type & Trait Personality can be described by identifiable traits that Theory: carry characteristic behaviors. Type Theories: Ancient Greek humors, Sheldon’s somatotypes, divisions into Type A and Type B, and Myers-Briggs Type Inventory. Social Individuals react with their environment in a cycle called Trait Theories: PEN: Psychoticism (nonconformity), extraversion Cognitive reciprocal determinism. People mold their environments (sociable), neuroticism (arousal in stressful situations). Perspective: according to their personality, and those environments in Big Five: Openness, conscientiousness, extraversion, turn shape their thoughts, feelings and behaviors. agreeableness, and neuroticism. OCEAN mnemonic. 3 Basic Traits: Cardinal traits (traits around which Behaviorist Our personality develops as a result of operant person organizes their life), central traits (major Perspective: conditioning. E.g. it is reward and punishment based. characteristics of personality), secondary traits (more personal characteristics and limited in occurrence). Biological Behavior can be explained as a result of genetic Perspective: expression. 7.1 Understanding Psychological Disorders 30 Day MCAT CHAPTER 7 - PSYCHOLOGICAL DISORDERS Behaviorist Approach: Classical and operant conditioning shapes the disorder.

Subcultures: A group of people within a culture that distinguish themselves from the primary culture. 8.2 Socialization 30 Day MCAT CHAPTER 8 - SOCIAL PROCESSESS, ATTITUDE AND BEHAVIOR Socialization: The process of internalizing the social norms and values expected in one’s society. Sanctions: Positive: A reward for a certain behavior. Negative: A punishment for a certain behavior. Formal Sanction: An official reward or punishment. Informal Sanction: A sanction that is not enforced or punished by an authority but that occurs in everyday interactions with other people. Ex: Asking someone to lower their voice in a movie theater. Norms: Determine the boundaries of acceptable behavior within a society. Mores: Informal norms with major importance for society and, if broken, can result in severe sanctions. Ex: Taboos: Considered unacceptable by almost every culture (like Drug abuse is not socially acceptable. “Right / Wrong” cannibalism or incest).
