Change in response due the behavioral state shift. The schematic diagram represents the two possible outcomes of cerebellar processing which is dependent on the animal behavioral state. In the upper panel the same sensory-motor information is presented to the cerebellar system, tough due to changes in precerebellar regions, the representation of this sensory-motor information might differ. In both behavioral states the cerebellum produces an output, received by other structures in the CNS, resulting in the animal having the same behavioral response. The lower panel describes a scenario in which the behavioral response should be different. Neuromodulation processes, occurring in different states, should be able to select the behavioral responses which are kept invariant.
