We demonstrate a directional disturbance in tactile identification of the toes in healthy humans. Nineteen young adult participants underwent tactile stimulation of the digits with the eyes closed and verbally reported the identity of the stimulated digit. In the majority of individuals, responses to the second and third toes were significantly biased toward the laterally neighboring digit. The directional bias was greater for the nondominant foot and was affected by the identity of the immediately preceding stimulated toe. Unexpectedly, 9\/19 participants reported the subjective experience of a \u201cmissing toe\u201d or \u201cmissing space\u201d during the protocol. These findings challenge current models of somatosensory localization, as they cannot be explained simply by a lack of distinct representations for toes compared with fingers, or by overt toe-finger correspondences. We present a novel theory of equal spatial representations of digit width combined with a \u201cpreceding neighbor\u201d effect to explain the observed phenomena. The diagnostic implications for neurological disorders that involve \u201cdigit agnosia\u201d are discussed.<\/jats:p>","DOI":"10.1177\/0301006615607122","type":"journal-article","created":{"date-parts":[[2015,9,29]],"date-time":"2015-09-29T20:23:44Z","timestamp":1443558224000},"page":"265-280","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Tactile Toe Agnosia and Percept of a \u201cMissing Toe\u201d in Healthy Humans"],"prefix":"10.1177","volume":"45","author":[{"given":"Nela","family":"Cicmil","sequence":"first","affiliation":[{"name":"Department of Physiology, Anatomy & Genetics, University of Oxford, UK"},{"name":"The Medical School, University of Oxford, John Radcliffe Hospital, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Achim P.","family":"Meyer","sequence":"additional","affiliation":[{"name":"Bernstein Center for Computational Neuroscience, Humboldt University, Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John F.","family":"Stein","sequence":"additional","affiliation":[{"name":"Department of Physiology, Anatomy & Genetics, University of Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,9,28]]},"reference":[{"key":"bibr1-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.63.7.1022"},{"key":"bibr2-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1037\/a0034690"},{"key":"bibr3-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1016\/S0166-2236(97)01136-3"},{"key":"bibr4-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1038\/35784"},{"key":"bibr5-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1068\/p7910"},{"key":"bibr6-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20661"},{"key":"bibr7-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1016\/j.bodyim.2014.04.001"},{"key":"bibr8-0301006615607122","volume-title":"The descent of man, and selection in relation to sex","author":"Darwin C.","year":"1871"},{"key":"bibr9-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1993.sp019824"},{"key":"bibr10-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511544880.012"},{"key":"bibr11-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1080\/713754287"},{"key":"bibr12-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1016\/0028-3932(87)90141-2"},{"key":"bibr13-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1994.sp020369"},{"key":"bibr14-0301006615607122","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2007.11.001"},{"key":"bibr15-0301006615607122","first-page":"179","volume":"93","author":"Freund H.
