In humans, the extension of the near peripersonal space is revealed by an increase in the severity of cross\u2010modal extinction caused by visual stimulation at the distal edge of a rake after its use as a reaching tool. The crucial question addressed here concerns whether the dynamic re\u2010sizing of the peri\u2010hand space in humans constitutes a real spatial expansion of visual\u2010tactile peri\u2010hand area along the tool axis. Alternatively, it could constitute a shift of the integrative area from the hand towards the distal edge of the tool, or the formation of a novel visual\u2010tactile integrative area at the same distal location (). We contrasted the alternative predictions made by these hypotheses in a group of RBD patients by probing, at different locations along the tool axis, the changes induced by tool\u2010use on cross\u2010modal extinction. By assessing the visual\u2010tactile extinction near the hand, midway along the tool, and at the distal edge of the tool we found an increase in visual\u2010tactile extinction after tool\u2010use both at the middle and the distal location along the tool axis. In contrast, no change intervened at the hand proximity. These findings support the view that the tool\u2010use dependent re\u2010mapping of peri\u2010hand space in humans consists of a continuous elongation of visual\u2010tactile peri\u2010hand area from the hand towards the tip of the tool.<\/jats:p>","DOI":"10.1348\/174866407x180846","type":"journal-article","created":{"date-parts":[[2007,6,6]],"date-time":"2007-06-06T19:00:05Z","timestamp":1181156405000},"page":"101-114","source":"Crossref","is-referenced-by-count":44,"title":["Dynamic size\u2010change of peri\u2010hand space through tool\u2010use: Spatial extension or shift of the multi\u2010sensory area"],"prefix":"10.1111","volume":"1","author":[{"given":"S.","family":"Bonifazi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Farn\u00e8","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Rinaldesi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"L\u00e0davas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,12,24]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/neucas\/8.1.1"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/nn1480"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1162\/089892900562237"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1006\/nimg.2001.0817"},{"key":"e_1_2_6_6_1","volume-title":"Lesion analysis in neuropsychology","author":"Damasio H.","year":"1989"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/41921"},{"key":"e_1_2_6_8_1","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1093\/oso\/9780198542841.003.0012","volume-title":"Brain and space","author":"Duhamel J.
