Visuomotor representations

2003
Abstract This chapter considers both conceptual reasons and empirical evidence in favour of the dualistic model of the human visual system applied to the vision of objects. It examines the contribution of the visual system to a restricted class of human actions — reaching, grasping and manipulating objects in one's vicinity — and argues ...

Drawing under visuomotor incongruence

Experimental Brain Research, 1999
Six human subjects were asked to draw ellipses presented on a screen by moving a manipulandum that controlled the position of a cursor. Six visual templates were used, which comprised three different ellipses displayed either horizontally or vertically; the ratio between the major and minor axes was 2, 4, or 5.

Modular decomposition in visuomotor learning

Nature, 1997
The principle of 'divide-and-conquer' the decomposition of a complex task into simpler subtasks each learned by a separate module, has been proposed as a computational strategy during learning. We explore the possibility that the human motor system uses such a modular decomposition strategy to learn the visuomotor map, the relationship between visual ...

Stress modulation of visuomotor binding

Neuropsychologia, 2008
The primate cortex represents perceived and produced events in a distributed way, which calls for a mechanism that integrates their features into coherent structures. Animal, drug, and patient studies suggest that the local binding of visual features is under muscarinic-cholinergic control, whereas visuomotor binding seems to be driven by dopaminergic ...

Visuomotor learning in cerebellar patients

Behavioural Brain Research, 1996
The aim of the present study was to demonstrate that patients with pathology affecting substantial regions of the cerebellum can improve their performance in a series of two-dimensional tracing tasks, thus supporting the view that this type of motor behavior can be acquired even when the integrity of this structure is compromised.

Vulnerability in Speed of Visuomotor Ability

2014
The aim of this report is to illustrate the utility of neurocognitive testing as an investigative method to establish the presence of persistent effects of concussive brain injury amongst players of a contact sport with high risk of such injury. The report reviews the outcomes of three previously published neuropsychological studies on South African ...

Additive convergence for visuomotor decisions

Trends in Neurosciences
In a recent study, Slangewal et al. explored principles of visuomotor decision-making in larval zebrafish. Visuomotor choices were revealed to be largely additive, integrating visual motion, luminance level, and luminance change during cue conflict.

Visuomotor Families

Data and analysis code for "Soft categorization in motor memory: graded credit assignment for families of visuomotor mappings" (Onagawa, Birenbaum, Zhu, Gallivan & Flanagan). Participants made center-out reaches in VR under a visuomotor gain that varied with reach direction, with one outlier target whose gain departed from the family pattern.
