Researchers have identified a new mechanism that underlies dopamine release in the brain. The research, conducted in mice, shows that another chemical messenger called acetylcholine can trigger the ...

A team of scientists at Harvard Medical School (HMS) has identified a new mechanism of dopamine release in the brain in a study conducted in mice that was published in the journal Science (“An action ...

Acetylcholine (ACh) is a neuromodulator with a central role in aversive learning - rapid conditioning to unpleasant smell, taste, or touch. These learning functions play out in cells called D2 ...

Researchers have long thought that rewards like food or money encourage learning in the brain by causing the release of the 'feel-good' hormone dopamine, known to reinforce storage of new information.

Scientists at the NIH have discovered that blocking certain acetylcholine receptors in the lateral habenula (LHb), an area of the brain that balances reward and aversion, made it harder to resist ...

To give yourself the best chance of avoiding dementia, there are certain brain games that help and many that don't. The ones ...

When we initiate an action in our everyday lives—chasing after a runaway napkin or getting out of the car—the brain releases a chemical messenger called dopamine that helps regulate the brain area ...

Stedman and Stedman have stated in a recent issue of NATURE 1 that the presence of acetoacetate leads to acetylcholine synthesis in the brain. The evidence for this conclusion is apparently the fact ...
