Climbing fiber receptive fields are a physiological marker that have proven useful to delineate the details of the olivocerebellar circuitry. They have also proven useful as a point of reference to delineate the organization of other parts of the cerebellar circuitry. But what does the location of the climbing fiber receptive field imply and what is its relation to the presumed role of the cerebellum in coordination? Can we expect that all climbing fibers have a peripheral receptive field on the skin? In this short review, we aim to cover these issues.
