Such responses have been measured extensively in the cochlear base of laboratory mammals, and our understanding of human cochlear mechanics is largely founded on the assumption that cochlear mechanics is similar in all mammals. Here we show that the anatomy and motion of the human cochlear partition differ in crucial ways from the generalized classic view of mammalian cochlear mechanics. Our results call into question this classic view. Establishing the features of human cochlear anatomy and function is important for understanding human hearing and for comparison with results from laboratory animals.<\/jats:p>","DOI":"10.1073\/pnas.1900787116","type":"journal-article","created":{"date-parts":[[2019,6,25]],"date-time":"2019-06-25T08:56:20Z","timestamp":1561452980000},"page":"13977-13982","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":39,"title":["Cochlear partition anatomy and motion in humans differ from the classic view of mammals"],"prefix":"10.1073","volume":"116","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4471-2029","authenticated-orcid":false,"given":"Stefan","family":"Raufer","sequence":"first","affiliation":[{"name":"Eaton-Peabody Laboratories, Massachusetts Eye and Ear, Boston, MA 02114;"},{"name":"Speech and Hearing Bioscience and Technology Program, Harvard University, Cambridge, MA 02138;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1774-4738","authenticated-orcid":false,"suffix":"Jr.","given":"John J.","family":"Guinan","sequence":"additional","affiliation":[{"name":"Eaton-Peabody Laboratories, Massachusetts Eye and Ear, Boston, MA 02114;"},{"name":"Speech and Hearing Bioscience and Technology Program, Harvard University, Cambridge, MA 02138;"},{"name":"Department of Otolaryngology, Harvard Medical School, Boston, MA 02115"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1377-1934","authenticated-orcid":false,"given":"Hideko Heidi","family":"Nakajima","sequence":"additional","affiliation":[{"name":"Eaton-Peabody Laboratories, Massachusetts Eye and Ear, Boston, MA 02114;"},{"name":"Speech and Hearing Bioscience and Technology Program, Harvard University, Cambridge, MA 02138;"},{"name":"Department of Otolaryngology, Harvard Medical School, Boston, MA 02115"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2019,6,24]]},"reference":[{"key":"e_1_3_3_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01796105"},{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-018-05483-z"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1157-16.2016"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1607428113"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1606317113"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1113\/JP273881"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1500038112"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1152\/jn.00702.2017"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.282.5395.1882"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.2140\/jomms.2009.4.755"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1121\/1.3290995"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1121\/1.4941249"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1121\/1.2385068"},{"key":"e_1_3_3_14_2","volume-title":"Experiments in Hearing","author":"von Bekesy G.","year":"1960","unstructured":"G. von Bekesy, Experiments in Hearing (Acoustical Society of America, 1960)."},{"key":"e_1_3_3_15_2","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1007\/978-94-009-6911-7_25","volume-title":"Mechanics of Hearing-Proceedings of the IUTAM\/ICA Symposium","author":"Kohlloeffel L.
