Abstract

The visual system is one of the most complex mechanisms for processing information obtained from the external world. Ocular movements can be categorized as fast or slow. Saccadic eye movements are conjugate and fast compared to vergence which are disjunctive and slow. Saccadic eye movements quickly shift the fovea to the object of interest. Vergence movements are disconjugate which provide depth perception. This investigation will compare the saccadic and vergence functional activity to investigate differences between the neural circuitry. There are two primary findings from this study. First, the vergence-related FEF region is more anterior compared to the saccade-related FEF area. Furthermore, there is additional activation within the parietal lobe for vergence.
