Basal Ganglia Neural Coding of Natural Action Sequences

In this study we present evidence that neurones in the basal ganglia code the serial order of syntactic (rule-driven) sequences of natural motor behaviour (rodent grooming). Neuronal activity was recorded from the striatum in freely behaving rats while they spontaneously groomed themselves. Offline, we analysed sequential patterns of movement in a frame-by-frame scan of video taped behaviour an...

Basal Ganglia Circuits: What's Now and Next?

ganglia model, there are two contributions devoted to this topic: a review dealing with cholinergic interneurons (Bonsi et al., 2011) and another review focusing on all different types of GABAergic striatal interneurons (Tepper et al., 2010). It is also worth noting that we wanted to stress the role played by subcortical basal ganglia loops in modulating basal ganglia function. Two contribution...

Extrastriatal Dopaminergic Circuits of the Basal Ganglia

The basal ganglia are comprised of the striatum, the external and internal segment of the globus pallidus (GPe and GPi, respectively), the subthalamic nucleus (STN), and the substantia nigra pars compacta and reticulata (SNc and SNr, respectively). Dopamine has long been identified as an important modulator of basal ganglia function in the striatum, and disturbances of striatal dopaminergic tra...

Basal Ganglia: Mechanisms for Action Selection

The basal ganglia are an interconnected circuit of foreand midbrain nuclei common to all extant vertebrates, including the lamprey, which diverged from the main vertebrate line approximately 560MYA.Moreover, there are analogous structures in birds and bony fish. The preservation of this circuit implies a crucial operation that solves a problem common to all vertebrates. While many functions for...

Action, time and the basal ganglia.

The ability to control the speed of movement is compromised in neurological disorders involving the basal ganglia, a set of subcortical cerebral nuclei that receive prominent dopaminergic projections from the midbrain. For example, bradykinesia, slowness of movement, is a major symptom of Parkinson's disease, whereas rapid tics are observed in patients with Tourette syndrome. Recent experimenta...
