A new study from the Department of Neuroscience at Karolinska Institutet characterizes a novel neuronal population in the basal ganglia, responsible for the interaction between two types of ...

Dopamine is a powerful signal in the brain, influencing our moods, motivations, movements, and more. The neurotransmitter is crucial for reward-based learning, a function that may be disrupted in a ...

The caudate nucleus (green) is a subcortical brain region located in the striatum. The striatum is one of several neural structures that make up the basal ganglia (colored regions) located below the ...

Exercise increases dopamine signaling in the motor areas of mice, according to research recently published in JNeurosci. It’s no secret exercise is good for the brain — working out can improve mood, ...

False-colour positron emission tomography (PET) scan highlighting limbic areas in a human brain. A receptor for the inhibitory neurotransmitter GABA is visualised here in regions of the brain ...

A Finnish clinical imaging study shows that rest tremor in Parkinson's disease is not explained by greater dopamine loss. In contrast, tremor appears to be associated with relatively better-preserved ...
