DIENCEPHALON

TELENCEPHALON

Primary Motor Cortex

Located in the precentral gyrus of the frontal lobeAllows conscious control of voluntary movements Composed of neurons called pyramidal cells -

axons project to spinal cord and make up the

voluntary motor tracts called corticospinal tracts

Primary Motor Cortex

Primary Somatosensory Cortex

Located in the postcentral gyrus of the parietal lobeReceives information from somatic sensory receptors

in the skin and proprioceptors in skeletal muscles

Exhibits spatial discrimination

Primary Somatosensory Cortex

Cerebral White Matter

Consists of myelinated fibers and their tracts

Responsible for communication

between the cerebral cortex and

lower CNS centers
