Abstract

Focal electrical stimulation of the brain of Periplaneta americana evokes the release of a factor with high cardioaccelerator activity. Results of extirpation of components of the retrocerebral complex from an isolated head preparation imply that the corpus cardiacum is the critical component of this system. The cardioaccelerator is a heat-stable proteinaceous compound.
