Outline of Final Research Achievements

It has been reported that the cerebellum is involved in higher brain function, such as cognition and emotion, as well as motor coordination and motor learning. We investigated whether the cerebellum worked during fear conditioning using Cbln1-null mice. It is already known that Cbln1 is predominantly expressed in cerebellar granule cells. Our detailed studies showed its weak, but significant expression in some forebrain regions. To differentiate the roles of cerebellar Cbln1 from those in the forebrain, we generated forebrain-specific (FB) and cerebellum-specific (CB) Cbln1-null mice. While the FB mice indicated reduced freezing in cued and contextual fear conditioning, only cued fear conditioning was blunted in the CB mice. The results suggest that cerebellar circuits that include parallel fiber-Purkinje cell synapses should be involved in cued fear conditioning.
