states of the brain can be often reflected as facial expressions. However, how animals show their facial expression is largely unexplored. Here we investigate whether a whisker of mice might convey some information of their internal states related to reward processing. We trained three mice for an auditory Go/No-Go task and filmed a whisker during task performance after the mice learned the task. We found that approximately 5-8 Hz periodic whisking was commonly observed during reward-associated “Go” cue presentation. Such whisking rarely occurred in “No-Go” trials or in “Go” trials where the mice were not motivated to get a reward. Furthermore, after acquiring a reward, the mice whisked with a more protracted set-point. Using machine learning, we obtained a computer algorithm that could accurately indicate reward-anticipating and reward-acquiring trials only from whisker time plots. Our analyses suggest that mice exhibit stereotypic whisker movements as a part of orofacial movements related to reward anticipation and acquisition.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告バイオ情報学（BIO）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2019-03-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2019-BIO-57"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":194995,"links":{}}
