Three timescales in prism adaptation.
It has been proposed that motor adaptation depends on at least two learning systems, one that learns fast but with poor retention and another that learns slowly but with better retention (Smith MA, Ghazizadeh A, Shadmehr R. PLoS Biol 4: e179, 2006). This two-state model has been shown to account for a range of behavior in the force field adaptation task. In the present study, we examined whethe...
متن کاملPrism adaptation in Parkinson's disease.
Prism adaptation is impaired by lesions in the basal ganglia in non-human primates, suggesting that this area is involved in this form of visuomotor learning. We investigated the ability of patients with Parkinson's disease to prism adapt. Patients and controls wore prisms which deflected vision laterally by 11 degrees. After baseline testing with a localisation task that permitted no feedback ...
متن کاملAttention and prism adaptation.
For both lateral displacement and rotation of the visual field, visual adaptation was reduced when subjects were required to perform a secondary cognitive task simultaneously with the primary exposure task of walking about hallways. Interference appeared to be independent of walking rate and occurred when the cognitive task was either mental imagery or mental arithmetic. A tentative model is pr...
متن کاملGeneralization of prism adaptation.
Prism exposure produces 2 kinds of adaptive response. Recalibration is ordinary strategic remapping of spatially coded movement commands to rapidly reduce performance error. Realignment is the extraordinary process of transforming spatial maps to bring the origins of coordinate systems into correspondence. Realignment occurs when spatial discordance signals noncorrespondence between spatial map...
متن کاملReacquisition deficits in prism adaptation after muscimol microinjection into the ventral premotor cortex of monkeys.
A small amount of muscimol (1 microl; concentration, 5 microg/microl) was injected into the ventral and dorsal premotor cortex areas (PMv and PMd, respectively) of monkeys, which then were required to perform a visually guided reaching task. For the task, the monkeys were required to reach for a target soon after it was presented on a screen. While performing the task, the monkeys' eyes were co...
