The investigation presented here was aimed at clarifying the possible role of the hypothalamus in the genesis of some electrocardiographic configurations of clinical interest.METHODSIn the present study the hypothalamus of the cat was explored throughout by means of the Horsley-Clarke apparatus. Three hundred seventy-five individual diencephalic points were electrically stimulated in 10 animals. The location of each point stimulated by the tip of the electrode was...Bibliography1.
