Switching from automatic to controlled behavior: cortico-basal ganglia mechanisms.

Most daily tasks are performed almost automatically, but occasionally it is necessary to alter a routine if something changes in the environment and the routine behavior becomes inappropriate. Such behavioral switching can occur either retroactively based on error feedback or proactively by detecting a contextual cue. Recent imaging and electrophysiological data in humans and monkeys support th...

Cortico-Basal Ganglia Interactions in Huntington’s Disease

Huntington’s disease (HD) is an autosomal dominant neurodegenerative disorder characterized by involuntary movement, cognitive and psychiatric disturbances. The disease is caused by an expansion of polyglutamine repeats in the N-terminal domain of the huntington protein. Despite the single gene etiology, there is major variability in the neuropathology, as well as major heterogeneity in the sym...

Brain mechanisms for switching from automatic to controlled eye movements.

Human behaviour is mostly composed of habitual actions that require little conscious control. Such actions may become invalid if the environment changes, at which point we need to switch behaviour by overcoming habitual actions that are otherwise triggered automatically. It is unclear how the brain controls this type of behavioural switching. Here we show that the presupplementary motor area (p...

Pausing to Regroup: Thalamic Gating of Cortico-Basal Ganglia Networks

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.

Monitoring and switching of cortico-basal ganglia loop functions by the thalamo-striatal system.

Recent physiological and tract tracing studies revealed tight coupling of the centre médian and parafascicular nuclei (the CM-Pf complex), which are posterior intralaminar nuclei (ILN) of the thalamus, with basal ganglia circuits. These nuclei have previously been classified as part of the ascending reticulo-thalamo-cortical activating system, with studies of single neuron activity and of inter...
