Sensory acquisition in the cerebellum: an FMRI study of cerebrocerebellar interaction during visual duration discrimination.
It has been suggested that the cerebellum participates in diverse neuropsychological functions by adjusting the sensory information acquired for the connected brain regions to support its processing capabilities. Nevertheless, the knowledge of how the cerebellum is modulated by the sensory information is far from clear. Function magnetic resonance imaging was exploited to investigate how the cerebellum activity and cerebrocerebellum interaction can be affected by the interaction between visual size and duration information during visual duration discrimination. The present findings support the sensory acquisition hypothesis that the cerebellum, together with extensive cortical networks, yields higher activation with incongruent sensory information to cope with increasing cortical computational demand. Furthermore, comprehensive intracerebellum connections are engaged in tasks with congruent sensory information for saving cortical computation with integrated sensory information.
