A comprehensive gaze stabilization controller based on cerebellar internal models

Bioinspiration & Biomimetics
Two kind of reflexes, which rely on the output of the inertial system and are used to keep the image stable on the retina, exist: the vestibulo-ocular reflex (VOR), which stabilizes the visual axis to ...
To test this hypothesis, Ito and colleagues (Ito et al. 1977) studied the influence of a stimulation applied to the inferior olivary or to the optic tract to the vestibulo-ocular reflex. ...

Finally, we suggest SGDEGE may also operate in the basal ganglia. ...
The cerebellum aids the learning of fast, coordinated movements. According to current consensus, erroneously active parallel fibre synapses are depressed by complex spikes signalling movement errors. ...
Such predictable and constrained movements, exemplified by eye movements and simple reflexes, provide some of the best studied models of cerebellar learning: the vestibulo-ocular reflex (Robinson, 1976 ...
