چکیده

How the cholinergic and dopaminergic systems of the striatum interact and how these interface with the massive neocortical input to the striatum are classic questions of cardinal interest to neurology and psychiatry. In this issue of Neuron, Ding and colleagues show that a key to these puzzles lies in the thalamic inputs to the striatum targeting its cholinergic interneurons.

Functional immaturity of cortico-basal ganglia networks in Gilles de la Tourette syndrome.

Gilles de la Tourette syndrome is a clinically heterogeneous disorder with poor known pathophysiology. Recent neuropathological and structural neuroimaging data pointed to the dysfunction of cortico-basal ganglia networks. Nonetheless, it is not clear how these structural changes alter the functional activity of the brain and lead to heterogeneous clinical expressions of the syndrome. The objec...

Working memory and response selection: A computational account of interactions among cortico-basalganglio-thalamic loops

Cortico-basalganglio-thalamic loops are involved in both cognitive processes and motor control. We present a biologically meaningful computational model of how these loops contribute to the organization of working memory and the development of response behavior. Via reinforcement learning in basal ganglia, the model develops flexible control of working memory within prefrontal loops and achieve...

A spiking neural network based on the basal ganglia functional anatomy

We introduce a spiking neural network of the basal ganglia capable of learning stimulus-action associations. We model learning in the three major basal ganglia pathways, direct, indirect and hyperdirect, by spike time dependent learning and considering the amount of dopamine available (reward). Moreover, we allow to learn a cortico-thalamic pathway that bypasses the basal ganglia. As a result t...

Basal ganglia play a crucial role in decision making

Many studies have suggested that the striatum, located at the interface of the cortico-basal ganglia-thalamic circuit, consists of separate circuits that serve distinct functions It plays an important role in motor planning, value processing, and decision making.

A computational model that is able to generate sequences at arbitrary rates in a given serial order is presented for the cortico-basal ganglia (BG)–thalamic neural circuitry. Upon generating a sequence, this model stores information on the serial order of components in a cortical buffer by means of theta-nested gamma frequency oscillations observed experimentally in cortico-striatal neurons. Th...
