Study Notes

Auditory Sensory System

Responsible for hearing, detecting and processing sound waves.
Uses ears (outer, middle, and inner) to receive sound waves.
Sound waves vibrate the eardrum, transmitting signals to the brain.
Brain decodes signals into sounds (pitch, tone, volume, direction).
Hearing loss, tinnitus, and processing difficulties can result from damage.

Chemical Sensory Systems

Detect and process chemical stimuli (smell and taste).
Olfactory receptors detect smells.
Taste buds detect tastes (sweet, salty, bitter, sour, umami).
Smell is linked to memory and emotion.
Taste perception is influenced by genetics, age, and experience.
Key role in food preferences, safety, and social interaction.

Environmental Factors (Nurture)

External influences shaping development and behavior.
Includes family, societal norms, and culture.
Examples: parental upbringing, peer relationships, education, media.
Impacts personality, cognitive skills, emotional development, and mental health.
Researchers study interaction with genetics to understand human development and behavior.

Heredity (Nature)

Genetic transmission of characteristics from parents to offspring.
Genes influence physical and psychological traits.
Explains similarities among family members (intelligence, traits, health conditions).
Often studied using twin studies (identical vs. fraternal, raised together/apart).
Other methods: family and adoption studies.

Hormones and Neurotransmitter-like Actions

Chemical messengers regulating functions and behaviors.
Released by endocrine glands.
Impact neuronal communication (mood, cognition, physiological processes).
Affect emotions, stress responses, and body functioning.
Imbalances can contribute to mental health or physiological issues.

Neuron Structure and Function

Building blocks of the nervous system.
Cell body, dendrites (receive signals), axon (transmit signals).
Communication via electrochemical signals.
Synaptic vesicles store neurotransmitters.
Myelin sheath insulates and speeds signal conduction.
Communicate with thousands of other neurons.

Pain Sensory System

Network of nerve cells transmitting potential tissue damage signals to the brain.
Skin and internal organ receptors detect painful stimuli.
Nociceptors are specialized pain receptors.
Pain signals travel through the spinal cord to the brain.
Brain processes and interprets pain signals, impacting our perception of pain.

Research Methods on the Effects of Genes

Studying genetic influences on traits and behaviors.
Techniques: twin studies, gene editing.
Twin studies compare identical and fraternal twins.
Gene editing modifies specific genes.
Genome-wide association studies analyze populations for genetic links.
Animal studies help investigate behaviors in controlled environments.

Sleep/Wake Cycle

Alternating periods of sleep and wakefulness controlled by the body's internal clock.
Circadian rhythms regulate sleep-wake cycle.
Essential for overall health and well-being.
Disruption can lead to sleep disorders.
Factors: light exposure, lifestyle habits.

Structures and Functions of the Brain

Different regions with specific functions.
Cerebrum (higher functions), brainstem (basic survival).
Cerebral cortex (decision-making, planning).
Hippocampus (forming new memories).
Cerebellum (balance, coordination).
Amygdala (processing emotions).

Subsystems of the Human Nervous System

Central Nervous System (CNS) and Peripheral Nervous System (PNS).
CNS includes brain and spinal cord, processing information and sending signals.
PNS branches into somatic (voluntary movement) and autonomic (involuntary functions).
Autonomic further divides into sympathetic (fight or flight) and parasympathetic (rest and digest).
Neurons transmit information (electrical and chemical signals).

Touch Sensory System

Sensation of pressure, temperature, and pain from skin receptors.
Different receptors detect various stimuli.
Transmits sensory information to the brain.
Plays role in interactions with the environment.
Associated disorders can cause significant impairments.

Visual Sensory System

Processes visual information received by eyes, transmitted to brain for interpretation.
Includes eyes, optic nerves, and parts of brain responsible for vision.
Information enters through cornea, focuses on retina.
Retina has photoreceptor cells (rods and cones).
Light converted into electrical signals, sent to the brain via optic nerves.

Key Terms

(Accommodation):* Modifying existing cognitive structures to incorporate new information. Complementary to assimilation.
(Acetylcholine):* Neurotransmitter crucial for memory, attention, learning, and muscle contraction. Associated with Alzheimer's disease.
(Activation Synthesis Dream Theory):* Dreams are the brain interpreting random neural activity, creating stories.
(Addiction):* Compulsive engagement in rewarding stimuli despite negative consequences.
(Adrenaline):* Hormone released during stress or danger, triggering the fight-or-flight response.
(Afterimages):* Visual illusions of retained images after a stimulus is removed.
(Agonist drugs):* Mimic neurotransmitters, activating receptors for a response.
(Alcohol):* Depressant affecting the central nervous system leading to relaxation, lowered inhibitions, and impaired judgment.
(All-or-nothing principle):* Neurons either fire fully or not at all, no variation in intensity.
(Amplitude):* Strength or intensity of a sensory or emotional experience.
(Amygdala):* Brain region processing and regulating emotions, involved in the fight or flight response.
(Antagonist drugs):* Block neurotransmitters' action by binding to receptors without activating them.
(Aphasia):* Language disorder due to brain damage impairing speech, understanding, reading, or writing.
(Autonomic Nervous System):* Controls involuntary functions (heartbeat, digestion, breathing). Divided into sympathetic and parasympathetic systems.
(Biopsychology):* Study of biological factors influencing behavior and mental processes.
(Note):* Many more key terms are listed in the input but are too numerous to summarize. Continuing with the rest could take quite a few responses.
