Document Summary

Chapter 4: neurotransmitter processes and growth factor changes. Two basic cell types in the brain: neurons and glial cells. Release important chemicals for survival of neurons. Astrocytes: provide nutrients to neurons, maintain ion balance, important in repair and scarring of cells, communicate with other neurons. Oligodendrocytes: myelination of neurons in the cns. Dendrites to axon terminals & everything in between. Synaptic vesicles containing nt, released into clef and signals (epsp, ipsp) the post-synaptic neuron. Degradation (enzymes), reuptake (feedback mechanism to stop nt release once it is taken back up) Rich in the limbic brain regions (hippocampus, amygdala, pfc) Associated with executive functioning, and hormonal function (hypothalamus hpa, hpg) Nt helps us cope with the stressor and prevent other systems from overreacting. Your body may adapt to the increased utilization by maintaining a high level of nt production, however when the stressor leaves, the levels are still elevated for some time.
