Neuroimaging data suggesting cognitive involvement of the cerebellum ever increase, but one should be aware of a caution such that the observed activities might be contaminated by eye movements that often accompany cognitive tasks (Glickstein et al., 2009). It is also important to realize that the internal model-based control of mental activities presented above is still a conceptual hypothesis based on psychological aspects of Craik’s mental model and Piaget’s schema. Neuroimaging has made plausible that (1) activation of certain regions of the temporoparietal cortex is the neural substrate of a mental model or schema, and (2) activation of the cerebellum is an indication of the involvement of cerebellar internal models. This hypothesis is also supported to some degree by other experimental and clinicopathological data. It must be admitted, however, that further testing of the hypothesis is challenged by difficulties arising from current technical limitations in human experimentation and ....
