Document Summary

Biological psychology the study of the connection between biology and behavior. Biology behind behavior: the nervous system is living tissue composed of cells. Neurons nerve cells that receive, integrate, & transmit info. Types of neurons: sensory (afferent) neurons. Carry messages from sense organs spinal cord or brain: motor (efferent) neurons) Carry messages from the spinal cord or brain muscles and glands. Interneurons: mirror neurons (cid:271)rai(cid:374) (cid:862)(cid:373)irrors(cid:863) the (cid:373)ovement it sees (monkey see monkey do) Structure of a neuron: dendrites, soma, axon, myelin sheath what occurs when myelin layer is destroyed, terminal buttons, synapse. Communication between neurons: neurotransmitters are chemicals that transmit information from one neuron to another. Types of neurotransmitters: serotonin sleep, mood, hunger, endorphins pain relief and response to stress, pleasure, dopamine pleasurable emotions, voluntary movement. High: schizophrenia: acetylcholine (ach) voluntary movement (allows us to move), attention, memory. Alzhei(cid:373)er"s disease: norepinephrine arousal and mood.
