Change-of-mind neuroeconomic decision-making is modulated by LINC00473 in medial prefrontal cortex in a sex-dependent manner
Long non-coding RNA LINC00473 in mPFC alters change-of-mind re-evaluative decision-making behavior related to negative rumination.

Nicotine doesn’t just “turn on” the brain’s reward circuits — it reshapes them. Our new paper in Nature Communications shows that activating reward-linked dopamine neurons also sets off a feedback loop that drives negative emotional states.

Nicotine engages a VTA-NAc feedback loop to inhibit amygdala-projecting dopamine neurons and induce anxiety-like behaviors - Nature Communications
Drugs of abuse exert both motivational and emotional effects. Here, the authors show that nicotine and ethanol activate a VTA–NAc loop that inhibits dopamine neurons projecting to the amygdala, thereb...
