EFFERENT BRAIN DISCHARGE DURING SHIVERING

Abstract

Action potentials associated with shivering were recorded from the brain stem of the cat, with the use of large (25[mu] diameter) microelectrodes. The electrodes from which shivering action potentials were obtained were located within the efferent shivering pathway previously determined by lesion experiments. The range of frequencies from these units was between 6 and 26/second and appeared as a continuous stream of impulses having no rhythmic pattern.
