Recent studies have used auditory brainstem response (ABR) measurements to examine sound reception pathways. This study sought to determine how sound source placements, recording electrode arrangements, and ABR peak analyses affect interpretations of sound reception in the harbor porpoise (Phocoena phocoena). Click stimuli were delivered in air from a contact transducer (\u201cjawphone\u201d). Early ABR peaks (representing auditory nerve responses), and later peaks reflecting higher brainstem activity, were analyzed across jawphone and recording electrode positions. Auditory nerve responses were similar for jawphone placements from the ipsilateral posterior mandible to the tip of the rostrum. Later peaks, however, suggested a possible region of highest sensitivity midway between the posterior mandible and the rostrum tip. These findings are generally similar to previous data for porpoises. In contrast to auditory nerve responses that were largest when recorded near the ipsilateral meatus, later ABR peaks were largest when recorded with a contralateral (opposing) electrode. These results provide information on the processes underlying peaks of the ABR, and inform stimulus delivery and ABR recording parameters in odontocete sound reception studies.<\/jats:p>","DOI":"10.1121\/1.5030921","type":"journal-article","created":{"date-parts":[[2018,4,13]],"date-time":"2018-04-13T15:43:10Z","timestamp":1523634190000},"page":"2076-2084","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":6,"title":["Click reception in the harbor porpoise (<i>Phocoena phocoena<\/i>): Effects of electrode and contact transducer location on the auditory brainstem response"],"prefix":"10.1121","volume":"143","author":[{"given":"Jason","family":"Mulsow","sequence":"first","affiliation":[{"name":"National Marine Mammal Foundation 1 , 2240 Shelter Island Drive #200, San Diego, California 92106, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James J.","family":"Finneran","sequence":"additional","affiliation":[{"name":"U.S. Navy Marine Mammal Program, Space and Naval Warfare Systems Center Pacific 2 , Code 71510, 53560 Hull Street, San Diego, California 92152, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dorian S.","family":"Houser","sequence":"additional","affiliation":[{"name":"National Marine Mammal Foundation 1 , 2240 Shelter Island Drive #200, San Diego, California 92106, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chad A.","family":"Nordstrom","sequence":"additional","affiliation":[{"name":"Coastal Ocean Research Institute, Vancouver Aquarium 3 , 845 Avison Way, Vancouver, British Columbia V6G 3E2, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lance G.","family":"Barrett-Lennard","sequence":"additional","affiliation":[{"name":"Coastal Ocean Research Institute, Vancouver Aquarium 3 , 845 Avison Way, Vancouver, British Columbia V6G 3E2, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert F.","family":"Burkard","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Science, University at Buffalo 4 , 626 Kimball Tower, Buffalo, New York 14214, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2018,4,13]]},"reference":[{"key":"2023072701111386500_c1","first-page":"255","article-title":"Auditory sensitivity of the harbour porpoise Phocoena phocoena","volume-title":"Investigations on Cetaceans","author":"Pilleri","year":"1970"},{"key":"2023072701111386500_c2","doi-asserted-by":"crossref","first-page":"409","DOI":"10.1007\/978-1-4612-1150-1","article-title":"Acoustic models of sound production and propagation","volume-title":"Hearing by Whales and Dolphins","author":"Au","year":"2000"},{"first-page":"227","volume-title":"The Sonar of Dolphins","year":"1993","key":"2023072701111386500_c3"},{"key":"2023072701111386500_c4","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1007\/978-1-4615-3406-8","article-title":"Auditory brainstem responses in the Harbor Porpoise (Phocoena phocoena)","volume-title":"Marine Mammal Sensory Systems","author":"Thomas","year":"1992"},{"key":"2023072701111386500_c5","doi-asserted-by":"publisher","first-page":"295","DOI":"10.1134\/1.1739498","article-title":"What do evoked potentials tell us about the acoustic system of the harbor porpoise?","volume":"50","year":"2004","journal-title":"Acoust.
