Long-term fluctuation of cerebral electrical activity as related to coagulation of the connections between hypothalamus and hypophysis

Bulletin of Experimental Biology and Medicine Aims and scope

Summary

Daily electrical stimulation of one of the regions of the hypothalamus caused fluctuations of electrical activity, i.e., rhythmic changes of high-amplitude oscillations of augmented frequency and low-amplitude oscillations of a lower frequency to develop in the stimulated center and in some other regions of the brain. Each period lasted for several tens of minutes. The waves were found to continue for several hours after stimulation, and could be subdivided into two stages. Coagulation of the hypophysis and infundibulum not only failed to prevent the development of the fluctuations but even augmented them. A restricted coagulation of the tract between the supra-optic region and the hypophysis on one side caused an increase in the fluctuations in the dorso-medial thalamic nucleus. Chemical transmitters appearing in the hypothalamus may therefore be associated with the phenomenon.
