Therefore, auditory evoked potentials (AEPs) are used to evaluate central auditory processing, which is thought to contribute to speech perception in CI subjects. In AEPs, the P300 component reflects the cognitive ability of subjects to detect and respond to stimuli and has most frequently been used and investigated in CI subjects. Other studies have used mismatched negativity (MMN) to examine central auditory processing. It is important to compare MMN and P300 and examine the auditory processing mechanisms involved in these components. Our study therefore aimed to investigate the relationship between P300 and MMN using both active and passive hearing paradigms in CI and normal hearing (NH) subjects. METHODS: Our subjects consisted of 3 CI subjects and 3 NH subjects. An oddball paradigm was used to deliver the stimuli on both components. The frequent stimuli were 1,000-Hz tone bursts, whereas the rare stimuli were 1,500, 2,000, and 4,000-Hz. RESULTS: As the frequency contrasts increased, the P3 latencies increased in the CI subjects. However, the latency in NH subjects did not change significantly across the frequency contrast conditions. MMNs were identified for both the CI and NH subjects; the latencies in the CI subjects were longer than those in the NH subjects. However, there were no differences in the latencies of either the CI or NH subjects in the 3 frequency contrast tasks. CONCLUSION: Our results indicated that different auditory processing pathways are involved in the active and passive hearing conditions based on the P300 and MMN data and that a combination of both responses plays an important role in the comprehension of auditory processing mechanisms in CI subjects.", "subitem_description_type": "Abstract"}]}, "item_5_identifier_34": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2241/117355"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Korean Society of Otorhinolaryngology-Head and Neck Surgery"}]}, "item_5_relation_10": {"attribute_name": "PubMed\u756a\u53f7", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "22701150", "subitem_relation_type_select": "PMID"}}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.3342/ceo.2012.5.S1.S6", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2012 by Korean Society of Otorhinolaryngology-Head and Neck Surgery. \u3000This is an open-access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited."}]}, "item_5_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1976-8710", "subitem_source_identifier_type": "ISSN"}]}, "item_5_source_id_9": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA12333287", "subitem_source_identifier_type": "NCID"}]}, "item_5_subject_20": {"attribute_name": "NII\u30b5\u30d6\u30b8\u30a7\u30af\u30c8", "attribute_value_mlt": [{"subitem_subject": "\u751f\u547d\u79d1\u5b66", "subitem_subject_scheme": "Other"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Obuchi, Chie"}], "nameIdentifiers": [{"nameIdentifier": "94922", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Harashima, Tsuneo"}], "nameIdentifiers": [{"nameIdentifier": "94923", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shiroma, Masae"}], "nameIdentifiers": [{"nameIdentifier": "94924", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2013-12-25"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "CEO_5-S1.pdf", "filesize": [{"value": "377.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 377900.0, "url": {"label": "CEO_5-S1.pdf", "url": "https://tsukuba.repo.nii.ac.jp/record/27480/files/CEO_5-S1.pdf"}, "version_id": "86dc2547-b73e-4490-b469-f3adb75e70c9"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Auditory Evoked Potentials under Active and Passive Hearing Conditions in Adult Cochlear Implant Users", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Auditory Evoked Potentials under Active and Passive Hearing Conditions in Adult Cochlear Implant Users"}]}, "item_type_id": "5", "owner": "1", "path": ["2777/1968", "3/62/5298/1821"], "permalink_uri": "http://hdl.handle.net/2241/117355", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2012-07-03"}, "publish_date": "2012-07-03", "publish_status": "0", "recid": "27480", "relation": {}, "relation_version_is_last": true, "title": ["Auditory Evoked Potentials under Active and Passive Hearing Conditions in Adult Cochlear Implant Users"], "weko_shared_id": 5}
