On the amazing olivocerebellar system.

Over the last four decades elegant sets of a single-cell studies, originating from various research groups, have contributed significantly to our understanding of olivary and cerebellar physiology. Nevertheless questions relating to the dynamic properties of olivocerebellar network, as a system, remain unsolved. We may be reaching the limits of what can be learned using the single-cell recordings. Further research on this subject may require study of the spatiotemporal activity profiles of ensemble neuronal activity. This paper summarizes results obtained using voltage-sensitive dye imaging in inferior olive slices, and the use of mathematical modeling to address such activity profiles.
