ANP 330 Lecture Notes - Lecture 42: Optic Nerve, Optic Chiasm, Cerebral Peduncle
Document Summary
Group of nuclei and centers in cerebrum and diencephalon that are involved with emotional states, memories (long term), & behavioral drives. Functionally related areas in cerebrum, thalamus, & hypothalamus. Linking conscious areas of cerebrum with unconscious areas of brainstem. Automatic processing center referred to as the "little brain" attached to the rear of the brainstem via cerebral peduncles; separated from cerebrum by transverse fissure. *2 important functions- maintain balance & programming & fine tuning movements controlled at conscious and subconscious levels. *gray matter folia surrounds white matter arbor vitae. 12 pairs of nerves (part of pns) that connect to the brain and provide motor, sensory, and/or autonomic (parasympathetic) function. Only cranial nerves attached to cerebrum; carry special sensory info responsible for smell. Sight; carries visual info; passes through foramina - intersects at optic chiasm, continues as optic tracts to nuclei of left & right thalamus.
