    Description: The representation of pain in the cerebral cortex is less well understood than that of any other sensory system. However, with the use of magnetic resonance imaging and positron emission tomography in humans, it has now been demonstrated that painful heat causes significant activation of the contralateral anterior cingulate, secondary somatosensory, and primary somatosensory cortices. This contrasts with the predominant activation of primary somatosensory cortex caused by vibrotactile stimuli in similar experiments. Furthermore, the unilateral cingulate activation indicates that this forebrain area, thought to regulate emotions, contains an unexpectedly specific representation of pain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Talbot, J D -- Marrett, S -- Evans, A C -- Meyer, E -- Bushnell, M C -- Duncan, G H -- New York, N.Y. -- Science. 1991 Mar 15;251(4999):1355-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de neurophysiologie comportementale, Faculte de medecine dentaire, Universite de Montreal, Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2003220" target="_blank"〉PubMed〈/a〉

    Description: Cerebral activation was measured with positron emission tomography in ten human volunteers. The primary auditory cortex showed increased activity in response to noise bursts, whereas acoustically matched speech syllables activated secondary auditory cortices bilaterally. Instructions to make judgments about different attributes of the same speech signal resulted in activation of specific lateralized neural systems. Discrimination of phonetic structure led to increased activity in part of Broca's area of the left hemisphere, suggesting a role for articulatory recoding in phonetic perception. Processing changes in pitch produced activation of the right prefrontal cortex, consistent with the importance of right-hemisphere mechanisms in pitch perception.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zatorre, R J -- Evans, A C -- Meyer, E -- Gjedde, A -- New York, N.Y. -- Science. 1992 May 8;256(5058):846-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McConnell Brain Imaging Centre, Montreal Neurological Institute, McGill University, Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589767" target="_blank"〉PubMed〈/a〉

    Description: Linkage analysis of ten Utah kindreds and one Texas kindred with multiple cases of cutaneous malignant melanoma (CMM) provided evidence that a locus for familial melanoma susceptibility is in the chromosomal region 9p13-p22. The genetic markers analyzed reside in a candidate region on chromosome 9p21, previously implicated by the presence of homozygous deletions in melanoma tumors and by the presence of a germline deletion in an individual with eight independent melanomas. Multipoint linkage analysis was performed between the familial melanoma susceptibility locus (MLM) and two short tandem repeat markers, D9S126 and the interferon-alpha (IFNA) gene, which reside in the region of somatic loss in melanoma tumors. An analysis incorporating a partially penetrant dominant melanoma susceptibility locus places MLM near IFNA and D9S126 with a maximum location score of 12.71. Therefore, the region frequently deleted in melanoma tumors on 9p21 presumably contains a locus that plays a critical role in predisposition to familial melanoma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cannon-Albright, L A -- Goldgar, D E -- Meyer, L J -- Lewis, C M -- Anderson, D E -- Fountain, J W -- Hegi, M E -- Wiseman, R W -- Petty, E M -- Bale, A E -- CA 42014/CA/NCI NIH HHS/ -- CA 48711/CA/NCI NIH HHS/ -- RR 00064/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Nov 13;258(5085):1148-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, University of Utah School of Medicine, Salt Lake City 84132.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1439824" target="_blank"〉PubMed〈/a〉

    Description: Although many T cells carry two in-frame V alpha rearrangements, the products of both V alpha rearrangements have never been shown simultaneously on the surface of normal cells. With the use of monoclonal antibodies to V alpha 2, V alpha 12, and V alpha 24, up to one-third of mature T cells expressed two V alpha chains as part of two functional and independent T cell receptors (TCRs). Thus, the "one cell, one receptor" rule does not apply to a large subset of alpha beta T cells. Cells that belong to this dual TCR subset may be specific for a broader range of antigens than cells with a single receptor, which may be important for autoimmunity and alloreactivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Padovan, E -- Casorati, G -- Dellabona, P -- Meyer, S -- Brockhaus, M -- Lanzavecchia, A -- New York, N.Y. -- Science. 1993 Oct 15;262(5132):422-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Basel Institute for Immunology, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8211163" target="_blank"〉PubMed〈/a〉
