PSYC 273 Lecture Notes - Lecture 1: Myelin, Dendrite, Ventricular System
Document Summary
Interneurons: receive/send inputs & outputs to and from neurons. Unipolar (single axon that branches in 2 directions) Receives neurotransmitters: neuroplasticity: ability of nervous system to change in response to something, synapses come & go, dendrites change shape, gross neuroanatomy: features of nervous system to the unaided eye, gross=large. Brain: cerebral hemispheres: 1 of the 2 halves of the forebrain, cerebral cortex: outer covering of cerebral hemispheres, consists of nerve bodies & branches, gyrus: rigid/raised portion of brain. Consists of nerves that connect the brain & internal organs muscles with the sensory system: sulcus: crevice of brain. Regions of the brain: frontal- control panel : cognitive skills (emotions, problem. Increased heart rate & blood pressure, inhibits digestions. Heart rate slows, blow pressure drops, digestive process activates. Solving, memory, language, sexual behavior, impulse: parietal: processes sensory info (sensation & perception) like taste, temp, touch, temporal: processes sounds/hearing, occipital: processes vision/sight, cerebellum: balance & movement, pre-central gyrus: movement . , post-central gyrus: sensations .
