Anecdotally, we know that a difficult problem can often be solved by \u2018sleeping on it\u2019, but the mechanisms of off-line learning are unclear. In this talk, I will discuss evidence from human behavioural experiments and wireless electrophysiological recording in non-human primates that suggests sleep-dependent performance gains derive from cerebellar forward models. Put simply, during the day we learn \u2018if I do x, then y happens\u2019, while in sleep we invert this to learn \u2018if I want y to happen, then I should do x\u2019. This mechanism may be supported by coupled spindle oscillations mediating information transfer via cerebello-thalamo-cortical pathways, and represents a powerful, computationally-efficient solution to problems inherent in model-free reinforcement learning. Finally, I will speculate that this hypothesis may link observed learning deficits and reduced spindle density in conditions linked to cerebellar dysfunction including schizophrenia and autism.<\/p>\n","protected":false},"featured_media":0,"template":"","acf":[],"_links":{"self":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event\/1465"}],"collection":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event"}],"about":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/types\/event"}],"wp:attachment":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/media?parent=1465"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
