The Claim
Optogenetic activation of dopamine D1 receptor-expressing neurons in the prefrontal cortex that project to the paraventricular nucleus reduces anxiety-like behaviors in chronically stressed male mice, an effect identical to that produced by palatable food intake.
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 chronically stressed male mice, stimulating specific brain cells that connect the prefrontal cortex to the paraventricular nucleus reduces behaviors associated with anxiety, just as eating palatable food does.
See the scientific wording
Optogenetic activation of prefrontal cortex dopamine D1 receptor-expressing neurons projecting to the paraventricular nucleus reduces anxiety-like behaviors in chronically stressed male mice, mimicking the effect of palatable food intake.
When dopamine activates specific neurons in the front part of the brain, those neurons send signals to nearby inhibitory cells around the stress control center. These inhibitory cells then turn off the stress neurons, which lowers anxiety.
What the research says
1 studyThe study shows that eating tasty food turns on a brain pathway that calms stress centers in mice. The claim says turning on that same pathway with light does the same thing—and this study proves that pathway is powerful enough to reduce anxiety all on its own, whether triggered by food or light.
