I. Biological bases of behavior
Students should recognize biological psychology as a perspective of psychology. Specifically, students should recognize:
1. The organization of the nervous system into the CNS and PNS:
The Central Nervous System-CNS- Brain and Spinal Cord. The Peripheral Nervous System-PNS- are the Nerves outside of the brain and spinal cord.
2. The structure and functions of neurons:
Neurons are the basic building blocks of the nervous system. The human central nervous system contains about 100 billion neurons. Neurons have a communicative role in the nervous system. Neurons can receive, integrate, and transmit information.
3. How neurotransmitters are related to behavior:
Acetylcholine (Ach) - Activates motor neurons controlling skeletal muscles. Contributes to the regulation of attention, arousal, and memory. Some Ach receptors stimulated by nicotine (the nicotine acts like Ach itself and binds to receptor sites for Ach).
Dopamine (DA)......
