Hunger Games: Ghrelin and Brain Cells Dictate Feeding Behavior

A new study illuminates how the hormone ghrelin, released when hungry, influences feeding behavior in mice. Ghrelin activates specific neurons in the amygdala, a region primarily studied in the context of fear and reward, prompting food consumption and producing sensations of hunger and satisfaction.

Hunger Hormone Impacts Memory

The hunger hormone ghrelin doesn't just influence where and when animals eat, it also appears to have an impact on memory. Disrupting signaling of ghrelin to the vagus nerve caused rats to forget they had just eaten, even though the animals remembered they had just had access to food. Findings suggest disrupted ghrelin signaling could negatively impact episodic memory.
