PSY 3122 Study Guide - Motor Cortex, Autonomic Nervous System, Reuptake
Document Summary
Chapter 2: biological psychology, neuron, sensory neurons, motor neurons. 4 lobes of the cerebral cortex: frontal lobes, parietal lobes, occipital lobes, temporal lobes, motor cortex, sensory cortex, association areas, plasticity, corpus callosum, split brain, left hemisphere: verbal, right hemisphere: visual perception and the recognition of emotion. Potentials reach the end of an axon (the axon terminals), they stimulate the release of neurotransmitters. These chemical messengers carry a message from the sending neuron across the synapse to receptor sites on a receiving neuron. The sending neuron, in a process called reuptake, and then normally absorbs the excess neurotransmitter molecules in the synaptic gap. Cerebellum (attached to rear of brainstem, coordinates muscle movement and helps process sensory info): limbic system. Amygdala (inv with resp of anger or fear) Hypothalmus (inv with various bodily maintenance functions, pleasurable rewards, control over the hormonal system). Pituitary gland (master gland controls hypothalamus by stimulating it to trigger the release of hormones.
