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 identify how acetylcholine sets off a signal cascade in brain cells that directly influence aversive learning and memory formation. Patients with Alzheimer's disease (AD) have lower levels ...

Anticholinergic medications block acetylcholine (i.e., "vagusstoff") and inhibit parasympathetic nerve impulses by binding with this neurotransmitter's receptors. Over 600 medications are known to ...

This comprehensive review synthesizes a decade of human and animal research to explain how the gut and brain communicate ...

To study how a key chemical neuromodulator affects signaling in the brain's cortex, Garrett Neske, PhD, has received a three-year, $300,000 grant from the Whitehall Foundation, a nonprofit ...
