This is also true for the raccoon, at least for those parts representing proximal and axial body regions. Electrophysiologically, studies carried out in cats and monkeys have demonstrated that all sensory sub\u2010modalities cross in the callosum. Moreover, cells representing the paws and fingers, though occupying a large portion of areas SI and SII, seem to send proportionately fewer axons through the callosum than axial structures. No comparable study has been carried out in the raccoon. The purpose of the present experiment was therefore to investigate the functional organization of the callosal system in this animal by examining the receptive field properties of the somatosensory fibres crossing in the callosum.<\/jats:p><jats:p>Axonal activity was recorded directly through tungsten microelectrodes in the corpus callosum of eight raccoons. Results indicated that somatosensory information is transmitted in its rostral portion. Most receptive fields concerned axial and proximal body regions and the head and face. Some receptive fields represented para\u2010axial regions of the body and a few concerned the hands and fingers. Slowly and rapidly adapting fibres were found, as were all the sensory sub\u2010modalities tested. A substantial proportion of the axons had bilateral receptive fields.<\/jats:p><jats:p>These results are discussed in relation to those obtained in other species, with particular reference to: (1) the midline fusion hypothesis of callosal function; (2) the representation within this structure of the distal extremities, and (3) the origin of the bilateral receptive fields. \u00a9 1992 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/cne.903210111","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T23:02:47Z","timestamp":1104620567000},"page":"124-132","source":"Crossref","is-referenced-by-count":8,"title":["Somatosensory receptive field properties of corpus callosum fibres in the raccoon"],"prefix":"10.1002","volume":"321","author":[{"given":"Jean\u2010Paul","family":"Guillemot","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louis","family":"Richer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maurice","family":"Ptito","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel","family":"Guilbert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franco","family":"Lepore","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,9]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.901810305"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00236234"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.902830305"},{"key":"e_1_2_1_5_1","first-page":"20A","article-title":"Projections from the dorsal column nuclei to the ipsilateral ventral posterolateral nucleus of the cat thalamus","volume":"211","author":"Berkley K.
