Characterizing Purkinje Cell Responses And Cerebellar Influence On Fluid Licking In The Mouse, Jeri Lonece Bryant

Theses and Dissertations (ETD)

Rodents consume water by performing stereotypical, rhythmic licking movements which are believed to be driven by central pattern generating circuits located in the brainstem. Temporal aspects of rhythmic licking behavior have been shown to be represented in the olivo-cerebellar system in the form of population complex spike activity. These findings suggest that the olivo-cerebellar system is involved in the generating circuitry responsible for licking rhythm in rodents. However, the representation of licking in the simple spike activity of Purkinje cells and the consequences of loss of cerebellar function on licking behavior has not been quantified. I investigated the influence of …
