We propose to investigate neurotransmitter-regulated mechanisms of metabolic suppression in hibernating Arctic ground squirrels (AGS). Results from prior work have begun to identify brain regions, including the suprachiasmatic nucleus (SCN) with metabolic activity during torpor or early arousal thermogenesis and have developed the instrumentation to monitor glutamate release in these regions. Thus, the proposed studies are designed to test the hypotheses that glutamate release in the SCN of hibernating animals coordinates hibernation.
