PAPER Glucosensing neurons do more than just sense glucose
... Glucose is a prototypical short-term signal since its stores in the body are limited and the brain and other organs have a critical dependence upon it as a primary energy source. Thus, significant deviations from a fairly narrow range of plasma glucose levels lead to significant counter-regulatory r ...
