Interactions of ventral tract and dorsal column inputs into the cat cuneate nucleus.
In decerebrate- decerebellate cats with spinal lesions separating the dorsal column (DC) from the spinocervicothalamic and ventral tract (VT) pathways, conditioning VT stimulation activated a few, but inhibited most, of the cuneate neurons discharging to test DC stimulation. This VT input into the cuneate nucleus is mediated through the brain stem.
