audition
28
insular cortex in lateral sulcus
pain and taste
29
deep nuclei part of basal ganglia
globus pallidus caudate putamen
30
amygdala
deep nuclei involved in fear response and emotional memory
31
internal capsule
white matter tract Includes axons relaying sensory info from thalamus to cerebral cortex and axons relaying motor signals to motor neurons from the cerebral cortex to lower levels
