  • Title: Visual-vestibular interaction in vertical vestibular only neurons.
    Author: Blazquez PM, Highstein SM.
    Journal: Neuroreport; 2007 Aug 27; 18(13):1403-6. PubMed ID: 17762722.
    Abstract:
    The central nervous system combines information from different stimulus modalities to generate appropriate behaviors. For instance, vestibular and visual information are combined during oculomotor behavior. We used squirrel monkeys to study this signal combination on vestibular neurons that carry the vertical component of vestibular and visual (slow visual pathway, or optokinetic) signals. We found that these neurons contain a neuronal correlate of asymmetries observed in oculomotor behaviors, and that there is a relationship between their response to vestibular and visual (optokinetic) stimulation. We argue that if this relationship is maintained after learning, changes in one information pathway (e.g. vestibular) will result in changes in the other (e.g. visual), explaining the cross-modality plasticity observed in these systems after vestibulo-ocular reflex motor learning.
