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...
متن کاملTHE ROBOT BASAL GANGLIA: Action selection by an embedded model of the basal ganglia
Action selection is the task of resolving conflicts between multiple sensorimotor systems seeking access to the final common motor path. Recently, 2 we proposed that the basal ganglia may act to provide a biological solution to the problem of selection. To test this notion we have implemented a high level computational model of intrinsic basal ganglia circuitry and its interactions with simulat...
متن کاملBasal 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...
متن کاملRole of Basal Ganglia in Swallowing Process: A Systematic Review
Objectives: The basal ganglia (BG) controls different patterns of behavior by receiving inputs from sensory-motor and pre-motor cortex and projecting it to pre-frontal, pre-motor and supplementary motor areas. As the exact role of BG in swallowing process has not been fully determined, we aimed at reviewing the published data on neurological control in the swallowing technique to have a better ...
متن کاملThe basal ganglia and chunking of action repertoires.
The basal ganglia have been shown to contribute to habit and stimulus-response (S-R) learning. These forms of learning have the property of slow acquisition and, in humans, can occur without conscious awareness. This paper proposes that one aspect of basal ganglia-based learning is the recoding of cortically derived information within the striatum. Modular corticostriatal projection patterns, d...
