Long-latency responses evoked by ipsilateral sciatic nerve and hippocampal-fornix stimulation in barbiturized cats are associated with activation of corticospinal neurons. Differences in latency and configuration of generalized responses and patterns of relayed corticospinal neuron discharges indicate that a variety of extra-thalamic projections are involved in activation of Betz cells.
