1. In the decerebrate cat descending cervico‐lumbar reflex interactions from neck muscle nerves are absent, and those from forepaw nerves are reduced or absent. 2. Lesions restricted to the anterior pole of the suprasylvian gyrus regularly abolish descending cervico‐lumbar reflex interactions from neck muscle nerves. The same lesions may reduce or abolish descending cervico‐lumbar reflex interactions from forepaw nerves. 3. The ascending cortical looping pathway utilized in descending cervico‐lumbar reflex interactions is crossed, and the descending pathway from the cerebral cortex is bilateral.
