The present study was performed to provide evidence that dynamic neural processes underlie the reduction in dorsal spinocerebellar tract and spinoreticular tract neuron activity that occurs during active sleep. To ascertain the effect of local inhibition on the spontaneous and glutamate-evoked spike discharge of sensory tract neurons, preliminary control tests were performed during the state of quiet wakefulness, where GABA or glycine was co-administered in a sustained fashion during pulsatile release of glutamate to dorsal spinocerebellar tract (n=3) or spinoreticular tract (n=2) neurons. Extracellular recording experiments combined with juxtacellular application of glutamate were then performed on 20 antidromically identified dorsal spinocerebellar tract and spinoreticular tract neurons in the chronic intact cat as a function of sleep and wakefulness. The glutamate-evoked activity of a group of 10 sensory tract neurons (seven dorsal spinocerebellar tract, three spinoreticular tract), which exhibited a significant decrease in their spontaneous spike activity during active sleep, was examined. In contrast, the glutamate-evoked activity of a second group of eight sensory tract neurons (four dorsal spinocerebellar tract, four spinoreticular tract), which exhibited a significant increase in their spontaneous spike activity during active sleep, was not significantly altered in a state-dependent manner.These data indicate that, during natural active sleep, a dynamic neural process is engaged onto certain dorsal spinocerebellar tract and spinoreticular tract neurons, which in turn dampens sensory throughput to higher brain centers..

In recent years the traditional pathway for position sense in the lower extremities has been challenged and it has been proposed that in the upper spinal cord the relevant fibres ascend not in fasciculus gracilis but in the dorsolateral part of the lateral funiculus with the dorsal spinocerebellar tract. To determine whether this premise is correct we have re-examined the clinical findings of five patients with spinal cord lesions and 62 patients who had undergone medullary tractotomy at a level where the dorsal spinocerebellar tract overlies the spinal tract of V. Of the five patients with spinal cord lesions, four had interrupted dorsal columns but intact dorsal spinocerebellar tracts. Another patient with a severed dorsal spinocerebellar tract and an incomplete lesion of the dorsal columns had no loss of position or vibratory sense but possibly some tactile impairment. These observations do not support the premise that position sense from the lower extremities is carried by fibres of the dorsal spinocerebellar tract at any level but do support the traditionally accepted pathway for position sense.
Axons considered to originate from these cells were located in the dorsal half of the lateral funiculus at the level of L2, intermingled with axons of the dorsal spinocerebellar tract originating at the levels of Clarke's column.
