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 of basal ganglia functioning which ...

The basal ganglia and cerebellum are two major subcortical structures that influence multiple aspects of motor, cognitive and affective behavior 1,2,3,4,5.Both structures are densely ...

Striatum articles from across Nature Portfolio. Atom; RSS Feed; Definition. The striatum is a subcortical structure in the forebrain that forms the major input to the basal ganglia.

"The striatum is the main input structure in the basal ganglia, and is typically associated with motor function", says Principal Investigator Gilad Silberberg at the Department of Neuroscience.

A major part of the basal ganglia, the striatum, is composed of a patchwork of two types of tissue: the striosome and the matrix. However, even though they were discovered three decades ago, ...

Your basal ganglia know—so you can act accordingly. ... In addition to tracing the circuit farther upstream from the striatum and subthalamic nucleus toward the cerebral cortex—and ultimately, ...

Using a novel system, researchers found that a part of the basal ganglia called the striatum is not involved in action selection as previously thought. Instead, the striatum and the motor cortex ...

High risk for psychosis was associated with increased resting activity in the hippocampus, midbrain and basal ganglia, and subsequent resolution of high-risk state was associated with ...

A pleasant surprise or a nasty shock is likely to be a memorable experience. For instance, if you touch a hot oven, you very quickly learn not to do it again. Learning by trial-and-error, which can ...

In the late 1970s, Graybiel first identified how fiber connections within the basal ganglia's striatum create an anatomical architecture consisting of striosomes and a surrounding matrix (Graybiel ...

Now, using a novel system developed at Janelia, researchers led by the Dudman Lab found that a part of the basal ganglia called the striatum is not involved in action selection as previously thought.
