Synaptic connectivity of a novel cell population in the striatum

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 neurotransmitters, GABA and acetylcholine. ...

Smooth movements are achieved by stable basal ganglia activity

Smooth movements require coordinated control of muscles. Even a simple reaching movement involves coordinated movements of a person's shoulder, arm, wrist and fingers, which are controlled by temporally precise commands from ...

Skin biopsy can help identify patients with Parkinson's disease

The diagnosis of Parkinson's disease (PD) is currently based on consensus clinical criteria. A novel study reported in the Journal of Parkinson's Disease has found that the presence of neuronal deposits of the biomarker phosphorylated ...

Study offers new insights into basal ganglia diseases

Basal ganglia are deep grey matter structures in the brain involved in the control of posture and voluntary movements, cognition, behaviour, and motivational states. Several conditions are known to affect basal ganglia during ...
