McLean Telencephalon

lesions to the telencephalon

generally create contralateral sensory and motor signs

lesions to the telencephalon results

blindness, depression, seizures

telencephalon is involved in

perception, learning, short and long term memory, voluntary control of movement, sensory discrimination, thinking and planning

cortex consists of

lobes - frontal, parietal, temporal, piriform, occipital

white matter organization

corona radiata

corona radiata

carry axons from individual gyri into and out of the __internal capsules__

what connects the two hemispheres of the cortex?

commissures

what is the largest commissure?

corpus callosum

what commissure connects the two temporal lobes?

rostral

what commissure interconnects the pretectal nuclei?

caudal one and it also mediates the PLR

basal ganglia

locomotion and emotions

basal forebrain

memory

neocortex

only in mammals

6 layers

contains the lobes
