Abstract. The cerebellum plays a major role in motor control. It is thought
to mediate the acquisition of forward and inverse internal models of the body-
environment interaction [1]. In this study, the main processing components of
the cerebellar microcomplex are modelled as a network of spiking neural pop-
ulations. The model cerebellar circuit is shown to be suitable for learning both
forward and inverse models. A new coupling scheme is put forth to optimise on-
line adaptation and support offline learning. The proposed model is validated on
two procedural tasks and the simulation results are consistent with data from hu-
man experiments on adaptive motor control and sleep-dependent consolidation
[2, 3]. This work corroborates the hypothesis that both forward and inverse inter-
nal models can be learnt and stored by the same cerebellar circuit, and that their
