Description:
We compared three-dimensional structure-from-motion (3D-SFM) processing in awake monkeys and humans using functional magnetic resonance imaging. Occipital and midlevel extrastriate visual areas showed similar activation by 3D-SFM stimuli in both species. In contrast, intraparietal areas showed significant 3D-SFM activation in humans but not in monkeys. This suggests that human intraparietal cortex contains visuospatial processing areas that are not present in monkeys.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vanduffel, W -- Fize, D -- Peuskens, H -- Denys, K -- Sunaert, S -- Todd, J T -- Orban, G A -- New York, N.Y. -- Science. 2002 Oct 11;298(5592):413-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratorium voor Neuro- en Psychofysiologie, Katholieke Universiteit Leuven, Campus Gasthuisberg, Herestraat 49, Leuven B-3000, Belgium. wim@nmr.mgh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12376701" target="_blank"〉PubMed〈/a〉
