PSYC 4010 Lecture Notes - Neural Tube, Temporal Lobe, Neural Development
Document Summary
Between 10 and 20 billion neurons in the adult cortex. Between 50 and 200 billion glial (support) cells. Neocortex: speed up or slow down specific signals, they can inhibit certain neurons based on info they are getting. Great diversity in shape, form, and interconnections of neurons. Goal of studying development: how diversity is achieved, how each portion and structure of cns is integrated into a whole to allow coherent functioning. Brain stem: role in basic attention, arousal, and consciousness, all info to and from our body passes through the brain stem on the way to or from the brain, control very basic primitive behaviours in us. Involved in the coordination of voluntary motor movement, balance, and equilibrium and muscle tone: mainly involved in motor control, possibly involved in working memory. Occipital lobe: the center of our visual perception. Parietal lobe: can be divided into 2 functional regions. 1st function integrates sensory info to form a single perception (cognition)
