Document Summary

*if cerebral cortex is damaged, loss of memory occurs: basal nuclei (corpus striatum) initiate, coordinate and stops motor movements eliminates unnecessary movements skills memory (slow stereotypical movements ie. walking) inputs from cerebral cortex outputs to motor cortex via thalamus. Motor planning: 1st motor cortex just do it, reaches for drink, cerebellum how to do it, where drink is in space/coordinate movement, basal ganglia how fast to do it, grab it quickly. How to drink a beer: see beer, comes into brain thalamus, visual cortex, puts it all together, parietal cortex puts sensory information together, frontal cortex initiates drinking/doesn"t"t initiate drinking, sends information to 3 parts of the brain, motor cortex reaches for the beer, cerebellum needs to know where drink is in space/allows for coordination of motor movement, basal ganglia allows you to grab it quickly. Pineal sleep endocrine control clock circadian rhythms: melatonin secreted by pineal gland along with dopamine, tells you when you"re sleepy.
