Computer simulation of a cerebellar cortex compartment. I. General principles and properties of a neural net

Here, Marr's theory of the cerebellum is elaborated at a detailed cellular level. The experimental grounds for the theory are briefly reviewed and problems related to (mossy-fibres) - (granule cell) coding are formulated. The properties of several particular types of (mossy-fibres) - (granule cell) connection matrices are illustrated through computer simulation.
