| Research Abstract |
The mechanism of behavioral thermoregulation is unknown yet. Rats place their tails underneath their body trunks in the cold (tail-hiding behavior). Tail-hiding behavior was used as an indicator of natural thermoregulatory behavior in this study. This study demonstrated that fasting, ghrelin, and female hormone (i.e. estrogen) modulate tail-hiding behavior in the cold.
