Summary:
To investigate the effects of elevated levels of hypothalamic Ca++ or Na+ on behavioral and physiological thermoregulation in the rat, bilateral cannula were implanted in various sections of the hypothalamus. In a cold environment, the introduction of artificial cerebrospinal fluid with a Ca++ excess into the posterior hypothalamus was followed by a significant increase in bar holding for 250 watt red-bulb infrared heat. In a neutral environment, introduction of the Ca++- excess solution into the posterior hypothalamus caused a significant increase in body temperature. The introduction of artificial cerebrospinal fluid with a Na+ excess under the same conditions caused respectively a significant decrease in responding for heat and a significant decrease in body temperature. Placements in the preoptic-anterior hypothalamus and lateral hypothalamus produced no significant behavioral or physiological results under either chemical conditions.
