Appetite linked to stress

Researchers have uncovered a mechanism by which stress increases food drive in rats.

Researchers in the Hotchkiss Brain Institute (HBI) at the University of Calgary's Faculty of Medicine have uncovered a mechanism by which stress increases food drive in rats.

Researchers Jaideep Bains, PhD and Quentin Pittman, PhD, looked specifically at nerve cells (neurons) in the region of the brain called the hypothalamus.
