On the flip side, stimulating the dopamine pathway between the ventral tegmental ... neural circuits without affecting the ...

This pathway, an indirect connection to the ... which enters the striosomes from the cortex and the limbic system, influences dopamine levels in a way that can encourage or discourage action.

The findings suggest that the classical model of how the striatum controls movement needs to be modified to include the role of these newly identified pathways. The researchers now hope to test their ...

Drugs of abuse mimic these effects, and hence, overexcite our brain’s natural reward system. Therefore, tempering drug-induced amplification ... Postsynaptically, A1 receptors are co-expressed with ...

This study utilizes an elegant approach to examine valence encoding of the mesolimbic dopamine system. The findings are valuable, demonstrating differential responses of dopamine to the same taste ...

Howard Hughes Medical Institute researchers have pinpointed defects in a critical cellular pathway that can lead to the death of dopamine-producing nerve cells and ultimately symptoms of Parkinson’s ...

Scientists have recently discovered that caffeine may counteract some of alcohol’s effects on the brain’s reward system, ...
