Study Notes
Behavioral Explanations of Camouflage
- Physiological Explanation: Links behavior to brain activity and physiological processes, influencing how organisms respond to their environment.
- Ontogenetic Explanation: Explains behavior development through nutrition, genes, experiences, and their interactions throughout an organism's life.
- Evolutionary Explanation: Examines how certain behaviors have evolved over time to improve chances of survival and reproduction.
- Functional Explanation: Addresses the purpose of behaviors, originating from internal drives, external rewards, conditioning, and social interactions.
Physiological Basis of Behavior
- Physiological Psychology: Studies responses of the body and how internal stimuli lead to action via mechanisms.
-
Mechanisms of Response:
- Receiving Mechanisms: Detect environmental stimuli.
- Connecting Mechanisms: Integrate and process sensory information.
- Reacting Mechanisms: Execute responses based on processed information.
Nervous System Overview
-
Role of the Nervous System:
- Monitors environmental changes.
- Processes sensory information.
- Manages bodily responses.
- Regulates mental activity.
- Maintains homeostasis.
-
Structural Classification:
- Central Nervous System (CNS): Comprises the brain and spinal cord.
- Peripheral Nervous System (PNS): Comprises nerves outside of the CNS.
-
Functional Classification:
- Sensory/Afferent division: Transmits sensory information to the CNS.
- Motor/Efferent division: Carries signals from the CNS to effectors in the body.
Components of the Nervous System
- Somatic Nervous System: Controls voluntary muscular movements.
-
Autonomic Nervous System: Regulates involuntary functions, sub-divided into:
- Sympathetic Nervous System: Prepares body for stress (fight or flight response).
- Parasympathetic Nervous System: Calms the body post-stress, regulating normal functions.
Major Structures of the Brain
-
Central Core (Old Brain): Includes brainstem and cerebellum; essential for basic life functions.
-
Brainstem: Connects brain to spinal cord; maintains vital functions.
- Medulla: Regulates heart rate, blood circulation, and respiration.
- Pons: Coordinates movements and integrates signals between brain parts.
- Midbrain: Smallest part that handles crucial reflexes and motor functions.
-
Cerebellum: Coordinates muscle movements, balance, and posture.
Limbic System
- Regulates emotions, learning, and memory.
- Vital for experiencing pleasure and emotional responses.
Glands and Hormones
- Endocrine Glands: Release hormones directly into the bloodstream; examples include the pituitary and adrenal glands.
- Pituitary Gland: Known as the master gland; regulates other glands and hormone secretion.
-
Adrenal Glands:
- Adrenal Cortex: Releases hormones affecting stress response and energy management.
- Adrenal Medulla: Produces adrenaline; enhances physical responses to stress.
- Pancreas: Secretes insulin for blood sugar regulation; key in diabetes management.
Neurotransmitters
- Definition: Chemical messengers facilitating communication between neurons at synapses.
- Serotonin: Regulates mood and cognition; linked to depression when levels are low.
- Glutamate: Most abundant excitatory neurotransmitter; crucial for normal brain functions including memory.
- Alcohol Effects: Enhances GABA (inhibitory neurotransmitter) effects, leading to sedative effects; impairs glutamate function, causing cognitive disruptions.
- Nicotine: Stimulates release of neurotransmitters like dopamine, linking to addiction.
Diseases Associated with Neurotransmitters
- Acetylcholine: Alzheimer's disease linked to its deficiency.
- Dopamine: Associated with Parkinson's disease and schizophrenia.
- GABA: Linked to epilepsy.
- Serotonin: Related to migraines, depression, and Attention Deficit Disorder.
- Glutamate: Implicated in migraines and strokes.
