functions of the amygdala

process and interpret sensory data, assigns emotional valence, modualtes cortical-hypothalamic flow, input to autonomic, endocrine and afffective responses

path of the "lizard brain"

sensory thalamus directly to amygdala

lesions of the splenium can cause

higher order visual issues
