  • Title: Effect of a local rise of temperature of the anterior hypothalamus on the electroencephalogram.
    Author: Yaichnikov IK.
    Journal: Neurosci Behav Physiol; 1980; 10(3):243-8. PubMed ID: 7413080.
    Abstract:
    In chronic experiments on rabbits the anterior hypothalamic region was heated by means of water thermodes. Heating the anterior hypothalamus to +3.0 degrees C caused no change in the character of the initial EEG. Heating the anterior hypothalamus to +6.0 degrees C caused activation of the initially synchronized EEG. The EEG weakly activated by heating the anterior hypothalamus to between +1.0 and +2.0 degrees C could be synchronized; this effect depended on the strength of the activating influences of the experimental external situation on the animal. The threshold of EEG activation by heating the anterior thalamus was 1.5-2 times higher than the threshold of activation of the EEG by cooling the anterior hypothalamus. In every case a change in the temperature of the anterior hypothalamus evoked appropriate thermoregulatory responses.
