Gnaw-y by nature: Researchers discover neural circuit that rewards gnawing behavior in rodents

Researchers at the University of Michigan have discovered that the constant gnawing of rodents isn't just a reflex or a consequence of a tough diet. It also triggers a release of dopamine in the brain—which acts as a biochemical reward or incentive—through a newly identified neural circuit.

Researchers Identify Brain Circuit That Drives Rewarding Gnawing Behavior

Researchers at the University of Michigan have uncovered a novel neural pathway that sheds light on the seemingly instinctual gnawing behavior seen in rodents. This discovery challenges the longstanding belief that such behavior is purely reflexive or mechanically driven by the need to manage continuously growing incisors. Instead, the study reveals that gnawing activates a […]
