Scientists are reporting the first compelling evidence in people that cognitive training can boost levels of a brain chemical that typically declines with age. A 10-week study of people 65 or older ...

Patients with Alzheimer's disease (AD) have lower levels of the neuromodulator acetylcholine (ACh) in their brains. Donepezil, an AD drug, increases brain ACh levels and improves AD-associated ...

New research published in Psychopharmacology shows that cannabidiol, a major non-psychoactive compound in cannabis, can enhance a specific type of social memory in mice. This effect appears to be ...

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 ...

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 ...

Within the human brain, movement is coordinated by a brain region called the striatum, which sends instructions to motor neurons in the brain. Those instructions are conveyed by two pathways, one that ...

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 ...
