Mirror drawing in a deafferented patient and normal subjects: visuoproprioceptive conflict

Neurology. 1992 May;42(5):1104-6. doi: 10.1212/wnl.42.5.1104.

Abstract

Results on a mirrow drawing task showed that a deafferented patient had no problem completing the pattern, whereas normal subjects needed more than four trials to attain a similar performance. The results suggest the presence of integrated visual and proprioceptive maps. The inversion of visual coordinates requires the need for a recalibration. Without proprioception, the task is more like a simple visual tracking task.
