The Claim
Pharmacological activation of glucocorticoid receptors in the ventral tegmental area of mice induces synaptic potentiation and increases intake of palatable food, replicating the effects of social stress.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In mice, activating glucocorticoid receptors in a specific brain region causes changes in brain synapses and increases consumption of highly rewarding foods, just like social stress does.
See the scientific wording
In mice, pharmacological activation of glucocorticoid receptors in the ventral tegmental area mimics the synaptic potentiation and increased palatable food intake caused by social stress, suggesting corticosterone signaling is a key mediator of stress-driven overeating.
When stress hormones bind to receptors in a brain region that controls reward, they strengthen the connection between two brain areas that drive eating behavior. This makes dopamine neurons more active when exposed to tasty food, causing the animal to eat more of it.
What the research says
1 studyThe study found that when mice are stressed, a brain connection between two areas gets stronger, making them eat more junk food. This supports the idea that stress affects the brain's reward system to cause overeating, even though it didn't use a stress hormone drug.
