  • Abstract
  • Look Inside

Effects of bulbar reticular tetanic stimulation on the responses of dorsal spinocerebellar tract (DSCT) units were studied in the decerebrate cat.

The conditioning stimulation of lateral or para-median reticular nucleus was found to reduce polysynaptic activation of DSCT cells (type 3 response) selectively without affecting either the spontaneous background discharge or the mono-synaptic activation (type 1 response) or inhibition (type 2 response) by afferent inputs from the peripheral nerves of hindleg.

These results show that the descending inhibition to the polysynaptic activation of DSCT cells occurs presynaptically by reticulospinal pathways from brain-stem reticular formation.
