An fMRI investigation in oculomotor learning through vergence eye movements

Binocular dysfunction in today´s population is expected to become an increasing problem as technological advances rely on near work, such as computer related activities. With an inability to fixate on an object, oculomotor learning within the vergence system must be understood to facilitate therapies for individuals with binocular dysfunction. Using fMRI to study oculomotor learning, cortical areas of the brain are to be located that are associated with motor learning in vergence eye movements. Preliminary data from two subjects show cortical activity in the occipital gyrus, V5/ MT, somatosensory area, and dorsolateral prefrontal cortex which are correlated to motor learning when prediction is utilized by vergence.
