S ummary Reticular evoked potentials in response to stimulation of the dorsal rootlet (L5) in the cat were recorded under FlaxCdil. Successive sections were made on the spinal cord at the level of Th 13. The amplitude of the reticular response was reduced and the latency was prolonged after section of the dorsal funiculi. Subsequent hemisection of the cord resulted in further delay of the reticular response when the stimulus was. given to the side sectioned, but the latency remained unchanged on stimulation of the opposite side. Stimulation of the dorsal funiculus gave rise to a reticular response. The reticular response is therefore evoked by afferent volleys ascending three reticulopetal connections of the cord: 1) contralateral dorsal funiculus, 2) ipsilateral path of the lateral funiculus and 3) ventrolateral tract of the contralateral side.
