Scientists have long studied the role of dopamine, a chemical in the brain that helps control learning and movement, in order ...

How does dopamine control both movement and learning? New research reveals that acetylcholine acts as a "switch" for dopamine ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

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 ...

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 MUSCLE can be made to contract by different stimuli. Thus, it may contract when pricked, when an electric current is passed through it, or if soaked in certain chemical substances. Among these, ...

In recent years, nootropics, also called smart drugs, have gained popularity among people looking to improve their mental performance. Acetylcholine is a neurotransmitter, or brain chemical, that ...

Acetylcholine is a chemical messenger, or neurotransmitter, that plays an important role in brain and muscle function. Imbalances in acetylcholine are linked with chronic conditions, such as Alzheimer ...

Botox inhibits the release of the neuro transmitter, acetylcholine, which is responsible for muscular contractions which leads to the formation of wrinkles. In a normal muscle, the place where a nerve ...

Acetylcholine is the main neurotransmitter involved in bladder contraction. Immunohistochemical staining of choline acetyltransferase has revealed the presence of a non-neuronal cholinergic system ...
