Frontal Lobe-fxn
Part of the brain that functions as an UMN center and contains the UMNs of the corticospinal tract; rostral to cruciate sulcus
Occipital Lobe-fxn
Area where the lateral geniculate projects for visual acuity; between parietal lobe and transverse fissure
Parietal Lobe-fxn
Part of the brain that perceives and integrates tactile; pain and proprioception information from the body and head; behind cruciate sulcus
Vermis-fxn
Structure that coordinates muscle tone and locomotor activity

Vestibular Trigone-fxn
Area where the vestibular nuclei are located
Caudate Nucleus-fxn
UMN area of the cerebrum that forms the lateral boundary of the lateral ventricle
