Notes
Biopsychology is the study of how biological processes influence behavior and mental processes.
Neurons are specialized cells that transmit information through electrical and chemical signals. They consist of dendrites, cell body, axon, and terminal buttons.
Synaptic transmission is the process by which neurons communicate. Action potentials travel down the axon, triggering the release of neurotransmitters into the synaptic cleft.
Neurotransmitters are chemical messengers that transmit signals across synapses. Examples include serotonin (mood), dopamine (reward), and acetylcholine (muscle control).
Central nervous system (CNS) consists of the brain and spinal cord. It processes information and coordinates responses.
Endocrine system releases hormones directly into the bloodstream to regulate bodily functions. Works more slowly than the nervous system but effects last longer.
AO3 Strengths: Scientific credibility, empirical evidence from brain scans and animal studies. Practical applications in medicine.
AO3 Limitations: Reductionist approach, ignores psychological and social factors. Ethical issues with animal research.
Summary
I understand the key components of biopsychology including neurons, synaptic transmission, neurotransmitters, and the central nervous system. Need to practice applying AO3 evaluation to exam questions and memorize specific neurotransmitter functions.
