The basal ganglia select the expected sensory input used for predictive coding
While considerable evidence supports the notion that lower-level interpretation of incoming sensory information is guided by top-down sensory expectations, less is known about the source of the sensory expectations or the mechanisms by which they are spread. Predictive coding theory proposes that sensory expectations flow down from higher-level association areas to lower-level sensory cortex. A...
متن کاملSensory and cognitive functions of the basal ganglia.
Recent studies have found that the basal ganglia are involved in diverse behavioral activities and suggest that they have executive functions. Highlights from the past year include anatomical and clinical studies that have used sophisticated, novel methods to confirm a role for the basal ganglia in somatosensory discrimination, visual perception, spatial working memory and habit learning.
متن کاملSatoshi Goto Abnormal sensory gating in basal ganglia disorders
Basal ganglia is a term to denote subcortical nuclei, consisting of the striatum (putamen or PUT and caudate nucleus or CN), the pallidum (internal and external globus pallidus or Gpi and GPe), sunthalamic nucleus (STN), and substantia nigra (pars compacta or SNc and pars reticulata or SNr). These structures are situated intermediate between the cerebral cortex (mainly frontal lobe) and the tha...
متن کاملBasal ganglia as a sensory gating devise for motor control.
Basal ganglia lie between the cerebral cortex and the thalamus, and have dense fiber connections between them. These connections form 4-5 distinct loops or circuits to allow parallel processing of information. Among them, the most intensively studied is the motor loop, which comprises 2 distinct direct and indirect pathways. The direct pathway disinhibits the powerful inhibition of the internal...
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 ...
