1)Subcortical fibers from adjacent regions of cortex(somatic sensory areas of the parietal cortex, frontal areas, visual cortex, auditory cortex)

2)Subcortical fibers that pass through the corpus callosum from the opposite cerebral hemisphere.

3)Somatic sensory fibers derived directly from the ventrobasal complex of the thalamus
;transmit mainly cutaneous tactile signals and joint and muscle signals.

4)Tracts from the ventrolateral and ventroanterior nuclei of thalamus
;coordination between the functions of the motor cortex, basal ganglia, and the cerebellum

5)Fibers from the intralaminar nuclei of the thalamus
;control the general level of excitability of the motor cortex
