Scientists have long studied the role of dopamine, a chemical in the brain that helps control learning and movement, in order to better understand Parkinson's disease, schizophrenia, and ...

A small burst of energy can change how a movement feels. It can make a reach quicker, a step lighter, or a motion more deliberate. Scientists have long sensed that this link between feeling and ...

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

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 ...

Dopamine is not just a reward signal — new research shows it precisely fine-tunes inhibitory brain circuits essential for learning, memory formation and mental health Wroclaw Medical University, ...

In A Nutshell A timing gap of just 50 to 100 milliseconds determines whether a dopamine signal in the brain drives learning or physical movement. A chemical called acetylcholine acts as a gatekeeper: ...

Dopamine is a signaling molecule or neurotransmitter that is known to help control emotions. Dopamine levels are also a biomarker of certain diseases. Researchers have now developed a rapid test that ...

Recently published research reports a relationship between neuron type and dopamine function, and one type of dopamine neuron has an unexpected function that will likely reshape how scientists, ...

Acetylcholine "conductors" in the striatum directly trigger serotonin release, offering new insights into the origins of OCD and chemical imbalances.
