PS100 Chapter Notes - Chapter 3: Neurotransmission, Neuroplasticity, Synaptic Vesicle
Document Summary
Study of the brain & nervous system. Experience in the environment also influences the brain & nervous system. Example: athletes as well as fans of a winning team tend to experience a rise in testosterone. Methods recording and imaging of brain activity opened whole new areas of inquiry to biological psychologists. Electrical stimulation of the brain imaging brain & structure (3d) functional mri, engaging in a task while imaging the brain. Based on the amount of o2 in blood. Measures activity in brain function & structure technique measures amount of o2 to the brain. Measures orientation and integrity of white matter to assess brain injury (e. g. , concussions) How fast water molecules move from one area to another. Sensors placed on the scalp measure electrical activity in the brain. Patients are awake and alert during this procedure. Neurons process information by communicating with each other. Glia & neurons are the basic components.
