AP Psychology/Biological Bases of Behavior
Introduces behaviors and mental processes from a biological perspective and explore the effects of the interaction between human biology and our environment.
Objectives and SkillsEdit
Topics may include:
- The interaction of inherited traits, environment, and evolution in shaping behavior
- Structures and functions of biological systems, including the endocrine system and nervous system
- Brain function, neural firing, and the influence of medication
- The study of the brain and research techniques for studying its structure and function
- States of consciousness, including sleeping and dreaming
- Addiction and drug dependence
- Phrenology - Different brain areas accounted for a specific character and personality traits (proposed by Franz Joseph Gall). You're the way you are because of the bumps on your head.
- Reuptake - Neurotransmitters in the synapse are reabsorbed into the sending neurons through the process of reuptake.
- Acetylcholine (ACL)
- Functions: Learning, memory.
- Problems: ACL deteriorates → causes Alzheimer [forgets stuff]
- Functions: Pleasure, movement.
- Problems: Not Enough → Parkinson's Disease (trembling, affects movement); Too much → Schizophrenia (two minds) (hereditary)
- Norepinephrine (NE)
- Functions: Mood, alertness.
- Problems: Not Enough → Depression.
- Serotonin (5-HT)
- Functions: Mood, appetite, sleep.
- Problems: Not Enough → Depression; Too much → Anxiety/No Dreams
- Examples: Zoloft, Lexapro, Prozae (inhibit serotonin reuptake inhibitors [SSRI]).
- Functions: Sleep, inhibits movement/effection axons, calming
- Problems: Helps to calm anxiety; Not Enough → Seizures, tremors, insomnia
- Functions: Memory, learning, synaptic plasticity (flexible)
- Problems: Too much → Overstimulate the brain, causing migraines or seizures.
- Functions: Inhibit neural regulators, pain-relief, treats pain.
- Examples: Heroin, morphine, opium
- Lock and Key Mechanism: Neurotransmitters bind to the receptors of the receiving neuron in a key-lock mechanism.
- Agonists: Similar to neurotransmitters and bind to its receptor sites to mimic its effects.
- Antagonists: Bind to receptors, but they BLOCK A neurotransmitter's function.
- Lesion - Tissue Destruction
- Autopsy - Postmortem Examination
