CORPUS CALLOSUM This fiber band connects all of the neurons from one hemisphere to the other

> Some important structures we can see is this big fiber tract here

insula - pain

precentral gyrus - primary motor cortex

So, you think about moving up here, you actually start moving here.

These are the neurons that talk to the ones in your brainstem and spinal cord which initiate voluntary movement.

The basal ganglia help initiate and smooth out voluntary muscle movements, suppress involuntary movements, and coordinate changes in posture. The cerebellum coordinates the body's movements, helps the limbs move smoothly and accurately, and helps maintain balance.

precentral gyrus/ postcentral gyrus

This postcentral gyrus is your primary somatosensory cortex
