A large number of computational models of information processing in the basal ganglia have been developed in recent years. Prominent in these are actor-critic models ...

Dopaminergic neurons in the basal ganglia normally fire in a random but continuous manner, so that striatal dopamine concentrations are maintained at a relatively constant level. In the dopamine ...

It receives inputs from the limbic system and the basal ganglia and sends outputs to midbrain areas that are involved in the release of dopamine (the substantia nigra pars compacta and ventral ...

"They're like classic motor go/no-go pathways, but they don't go to the motor output neurons of the basal ganglia. Instead, ...

"Our findings reveal that the basal ganglia—a brain circuit regulating adaptive behavior and motor functions—is affected in autism, with disruptions in how dopamine and acetylcholine work ...
