title: Visual allesthesia in manual pointing: some evidence for a sensorimotor cerebral organization.
abstract: The authors of this paper first summarize some of the theoretical frames put forward to account for allesthesia. Then, pointing performances in a case of visual allesthesia is reported; unexpectedly, pointing behavior for identical targets was different according to hand. The most salient feature was that a same visual target elicited relatively short RTs with adequate pointing using the left hand versus much longer reaction times with allesthesic pointing using the right hand. Discussion is focused on the presented theoretical frames. In view of the results, authors are led to hypothesize that, in sensorimotor cerebral organization, some aspects of signal processing are dependent upon some premotor aspects of response elaboration.
