SUMMARY:Seminar - Dr. Takayuki Yamashita
DESCRIPTION:Venue: CGFB \n\nSpeaker\nDr. Takayuki Yamashita\nFujita Health University\, Japan \nInvited by Naoya Takahashi (IINS) \nTitle\nUncovering the Neuronal Mechanisms of Uninstructed Orofacial Movements in Reward-Based Learning Behaviors \nAbstract\nDuring reward-based learning tasks\, animals make uninstructed orofacial movements that influence brain activity during reward anticipation and acquisition. Using task-performing mice\, we investigated the details of these movements and their neuronal mechanisms. Our results show that orofacial movements can be induced without any accompanying goal-directed actions. Moreover\, we found that the orofacial motions upon reward-expecting cue presentation and those upon reward acquisition differed in amplitude and vigor and were distinguishable by a machine learning model. We also discovered that the mesolimbic dopamine pathway and the whisker primary motor cortex coordinate to drive these movements differentially for distinct movements. In this talk\, I will provide an overview of our recent findings. \n
