The sound of silence? @AmitYaron &co show how #neurons encoding negative #PredictionErrors in the #AuditorySystem compute the omission of sounds in a predictable tone sequence (incl asymmetry between bottom-up receptive field & top-down predictive field @PLOSBiology https://plos.io/4n61zeq

Surprising input triggers a stronger response than expected input, but where's the prediction made? @D__Richter &co show that #PredictionErrors are computed at higher cortical levels; the resulting surprise signal is broadcast to earlier areas #PLOSBiology https://plos.io/48IMadt

How we learn from errors in our movements. @oza_anushka @MastishkayNamah @Apoorva___18 & @pratik_mutha show that learning mechanisms triggered by limb-related sensory #PredictionErrors & task-related performance errors are dissociable. While prediction errors drive implicit updates to motor plans, performance errors trigger deliberative selection of error-reducing actions. #PLOSBiology https://plos.io/4bxtb5t

Reminded of @PhilCorlett1 's recent review during his visit, which highlights cross-domain #FMRI correlates of #PredictionErrors in the #VentralStriatum, #AnteriorInsula, and #Midbrain:
