Document Summary
The reticular formation: nerve network in brainstem, enables alertness, helps filter incoming sensory information. Thalamus: relay center, directs sensory information to different parts of the cerebral cortex (except smell), and sends information from cortex to the medulla and cerebellum. Cerebellum: little brain , located at the back of the brainstem, fundamental to coordination of voluntary movement and balance, other functions: basic association. Working with the amygdala to form emotionally charged memories. Consists of 2 lima bean-sized neural clusters. Involved in experience of different emotions (fear) Directs endocrine system via messages to pituitary gland. Almost complete removal of hippocampus and amygdala. Anterograde amnesia (short term memory ok, but no long term memory, new tasks but not new knowledge) Circonvolutions: more surface area for 20+ billion neurons, grey matter (no myelin sheath, cannot be repaired) 180+ billion glial cells, which feed and protect neurons and assist in neural transmission. Parietal lobe: sensory info, touch and body position.
