However, it is not clear if amygdala stimulation has influences on the non-noxious response. The purpose of the present study is to determine using natural stimulation whether amygdala stimulation induces inhibition of noxious and non-noxious responses of wide-dynamic range (WDR) neurons. Rats were anesthetized with N_2O-O_2 and 0.5% halothane and immobilized with pancuronium bromide. Peripheral natural stimulus was applied continuously to the facial area, and ipsilateral amygdala stimulations (trains of 33 pulses, 0.5msec in duration, 300μA) to the recording site were delivered at a stimulus interval of 5-6sec. In 7 WDR neurons, noxious responses were inhibited by amygdala (central, cortical basomedial or basolateral nuclei) stimulation. Effects of amygdala stimulation on the responses to 3 kinds of stimuli (brushing, pressure and pinching) was tested in 4 neurons. In 3 of those neurons, both noxious and non-noxious responses were inhibited and the mean inhibitory effect were nearly equivalent (58.7-38.7%) for those responses. Amygdala stimulation inhibited noxious responses without affecting non-noxious responses in the remaining neuron. These inhibitory effects lasted for 200-300msec. In addition, responses of low-threshold mechanoreceptive (LTM) neurons were not affected by amygdala stimulation of the same site at which stimulation inhibited responses of nociceptive neurons. These findings suggest that excitation of neurons in the amygdala induce postsynaptic inhibition on the most of nociceptive neurons but not on non-nociceptive neurons in the medullary dorsal horn.", "subitem_description_type": "Other"}]}, "item_2_source_id_13": {"attribute_name": "雑誌書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00017474", "subitem_source_identifier_type": "NCID"}]}, "item_2_text_10": {"attribute_name": "著者所属(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Department of Orthodontics, School of Dentistry, Iwate Medical University"}, {"subitem_text_language": "en", "subitem_text_value": "Department of Oral Physiology, School of Dentistry, Iwate Medical University"}]}, "item_2_text_2": {"attribute_name": "記事種別(日)", "attribute_value_mlt": [{"subitem_text_value": "研究"}]}, "item_2_text_3": {"attribute_name": "記事種別(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Original"}]}, "item_2_text_9": {"attribute_name": "著者所属(日)", "attribute_value_mlt": [{"subitem_text_value": "岩手医科大学歯学部歯科矯正学講座"}, {"subitem_text_value": "岩手医科大学歯学部口腔生理学講座"}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2008-12-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00005130302.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "Creative Commons : 表示 - 非営利 - 改変禁止", "licensetype": "license_free", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "KJ00005130302", "url": "https://iwatemed.repo.nii.ac.jp/record/1582/files/KJ00005130302.pdf"}, "version_id": "633cdfe8-4b05-44ca-a0db-4623b86d6cf9"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "amygdala", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "antinociception", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "conditioning stimulation", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "trigeminal caudal nucleus", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "reticular subnulei", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "natural stimulation", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "stress-induced analgesia", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "ラットの末梢自然刺激による延髄後角の侵害受容細胞の応答に及ぼす扁桃体刺激の抑制効果", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "ラットの末梢自然刺激による延髄後角の侵害受容細胞の応答に及ぼす扁桃体刺激の抑制効果"}, {"subitem_title": "Inhibitory effects of amygdala stimulation on the responses of nociceptive neurons in the rat medullary dorsal horn to peripheral natural stimulation", "subitem_title_language": "en"}]}, "item_type_id": "2", "owner": "5", "path": ["116", "392"], "permalink_uri": "https://iwatemed.repo.nii.ac.jp/records/1582", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-12-19"}, "publish_date": "2008-12-19", "publish_status": "0", "recid": "1582", "relation": {}, "relation_version_is_last": true, "title": ["ラットの末梢自然刺激による延髄後角の侵害受容細胞の応答に及ぼす扁桃体刺激の抑制効果"], "weko_shared_id": 5}
