[An analysis of the hypothalamic mechanisms regulating cold hypobiosis in the frog Rana temporaria].
Experiments were made on intact frogs and after removal the anterior or the posterior hypothalamus. Data of spectral analysis of the EEG as well as quantitative evaluation of activation phenomena occurring spontaneously during hypobiosis are presented. Removal of the anterior hypothalamus did not affect the EEG parameters investigated, whereas lesion of the posterior hypothalamus significantly decreased cold-resistance capacities in frogs.
