The CNV is a negative voltage developing at the vertex after discrimination of one of two smells while the patient is expecting a second stimulus. By an adequate procedure, including a long time window for averaging (2.56 seconds) with appropriate filters, the two tests can be performed simultaneously in a single session of less than 10 minutes. Anosmia is determinable by both OEP and CNV, although CNV shows less variability. On the other hand, CNV requires attention and some cooperation of the patient. Parosmia is accessible by CNV only; two odor qualities presented in random order have to be distinguished. Hyposmia can also be detected; just above the discrimination threshold, CNV amplitudes tend to be large \u2014 even enhanced \u2014 whereas OEP amplitudes may still be undetectable.<\/jats:p>","DOI":"10.1177\/000348949310200102","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:38:05Z","timestamp":1412347085000},"page":"6-10","source":"Crossref","is-referenced-by-count":27,"title":["Olfactory Evoked Potentials and Contingent Negative Variation Simultaneously Recorded for Diagnosis of Smell Disorders"],"prefix":"10.1177","volume":"102","author":[{"given":"Heike","family":"Auffermann","sequence":"first","affiliation":[{"name":"Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Mathe","sequence":"additional","affiliation":[{"name":"Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00fcnther","family":"Gerull","sequence":"additional","affiliation":[{"name":"Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dieter","family":"Mrowinski","sequence":"additional","affiliation":[{"name":"Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1993,1,1]]},"reference":[{"key":"bibr1-000348949310200102","doi-asserted-by":"publisher","DOI":"10.1007\/BF00413126"},{"key":"bibr2-000348949310200102","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(67)90022-3"},{"key":"bibr3-000348949310200102","doi-asserted-by":"publisher","DOI":"10.1007\/BF02487128"},{"key":"bibr4-000348949310200102","doi-asserted-by":"publisher","DOI":"10.1007\/BF02413208"},{"key":"bibr5-000348949310200102","first-page":"135","volume":"9","author":"Kobal G","year":"1978","journal-title":"Z EEG EMG"},{"key":"bibr6-000348949310200102","volume-title":"Elektrophysiologische Untersuchungen des menschlichen Geruchssinns","author":"Kobal G","year":"1981"},{"key":"bibr7-000348949310200102","first-page":"101","volume":"7","author":"Sukhova AV","year":"1987","journal-title":"Biol Nauki"},{"key":"bibr8-000348949310200102","first-page":"37","volume":"6","author":"Gerull G","year":"1975","journal-title":"Z EEG EMG"},{"key":"bibr9-000348949310200102","doi-asserted-by":"publisher","DOI":"10.1007\/BF01109624"},{"key":"bibr10-000348949310200102","first-page":"125","volume":"12","author":"Gerull G","year":"1981","journal-title":"Z EEG EMG"},{"key":"bibr11-000348949310200102","first-page":"233","volume":"22","author":"Gerull G","year":"1974","journal-title":"HNO"},{"key":"bibr12-000348949310200102","doi-asserted-by":"publisher","DOI":"10.3109\/00206098009070078"},{"key":"bibr13-000348949310200102","doi-asserted-by":"publisher","DOI":"10.1037\/h0024146"}],"container-title":["Annals of Otology, Rhinology &amp; Laryngology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/000348949310200102","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/000348949310200102","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T11:12:30Z","timestamp":1777374750000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/000348949310200102"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,1]]},"references-count":13,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1993,1]]}},"alternative-id":["10.1177\/000348949310200102"],"URL":"https:\/\/doi.org\/10.1177\/000348949310200102","relation":{},"ISSN":["0003-4894","1943-572X"],"issn-type":[{"value":"0003-4894","type":"print"},{"value":"1943-572X","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,1]]}}}
