Letting aside differences at skin receptor level and afferent fibres, it is the CNS that makes a contextual selection of relevant sensory inputs. We hypothesized that subjective awareness (AW) of the time at which a sensory stimulus is perceived, a cortical function, may be differently modified by cortical stimulation, according to site and type of the stimulus. In 24 healthy volunteers, we examined the effects of transcranial direct current stimulation (<jats:styled-content style=\"fixed-case\">tDCS<\/jats:styled-content>) on the assessment of AW to heat pain or weak electrical stimuli applied to either the hand palm or dorsum. We also recorded the vertex\u2010evoked potentials to the same stimuli. The assessment was done before, during and after cathodal or anodal <jats:styled-content style=\"fixed-case\">tDCS<\/jats:styled-content> over the parietal cortex contralateral to the hand receiving the stimuli. At baseline, AW to thermal stimuli was significantly longer for palm than for dorsum (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.01), while no differences between stimulation sites were observed for the electrical stimuli. Both cathodal and anodal <jats:styled-content style=\"fixed-case\">tDCS<\/jats:styled-content> caused a significant shortening of AW to thermal stimuli in the palm but not in the dorsum, and no effects on AW to electrical stimuli. Longer AW in the palm than in the dorsum may be attributable to differences in skin thickness. However, the selectivity of the effects of <jats:styled-content style=\"fixed-case\">tDCS<\/jats:styled-content> on AW to thermal stimulation of the glabrous skin reflects the specificity of CNS processing for site and type of sensory inputs.<\/jats:p>","DOI":"10.1111\/ejn.12743","type":"journal-article","created":{"date-parts":[[2014,10,7]],"date-time":"2014-10-07T08:03:44Z","timestamp":1412669024000},"page":"3818-3827","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The effects of transcranial direct current stimulation on conscious perception of sensory inputs from hand palm and dorsum"],"prefix":"10.1111","volume":"40","author":[{"given":"Annette","family":"Westgeest","sequence":"first","affiliation":[{"name":"Leiden University Leiden The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Merche","family":"Morales","sequence":"additional","affiliation":[{"name":"Neurology Department Hospital Cl\u00ednic Institut d'Investigaci\u00f3 Biom\u00e8dica August Pi i Sunyer (IDIBAPS) Facultad de Medicina Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher","family":"Cabib","sequence":"additional","affiliation":[{"name":"Neurology Department Hospital Cl\u00ednic Institut d'Investigaci\u00f3 Biom\u00e8dica August Pi i Sunyer (IDIBAPS) Facultad de Medicina Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josep","family":"Valls\u2010Sole","sequence":"additional","affiliation":[{"name":"Neurology Department Hospital Cl\u00ednic Institut d'Investigaci\u00f3 Biom\u00e8dica August Pi i Sunyer (IDIBAPS) Facultad de Medicina Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,10,7]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.2008.02270.x"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpain.2011.07.001"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(92)90008-6"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3940(01)02374-6"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(89)90001-4"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroscience.2012.04.066"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/1475-925X-9-69"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pain.2006.02.023"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.1995.tb01229.x"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/00001756-199712010-00026"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pain.2005.02.017"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpain.2007.08.010"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brs.2010.12.002"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1388-2457(99)00192-3"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.3109\/07367228509144569"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pain.2010.06.026"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2044-8295.1998.tb02702.x"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2006.115675"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1532-2149.2012.00135.x"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1532-2149.2012.00167.x"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(93)90052-Q"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brs.2008.07.003"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/106.3.623"},{"key":"e_1_2_8_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neulet.2012.01.037"},{"key":"e_1_2_8_26_1","doi-asserted-by":"publisher","DOI":"10.1152\/jn.00483.2005"},{"key":"e_1_2_8_27_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1532-2149.2011.00105.x"},{"key":"e_1_2_8_28_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7793.2000.t01-1-00633.x"},{"key":"e_1_2_8_29_1","first-page":"463","article-title":"Transcranial direct current stimulation\u2013update 2011","volume":"29","author":"Nitsche M.A.","year":"2011","journal-title":"Restor.
