Instrumentation to stimulate gap saccades, pro-saccades, and overlap saccades
2014 40th Annual Northeast Bioengineering Conference (NEBEC), 2014Although a great amount of research studying oculomotor function has been conducted, a full understanding of how it relates to and is affected by neurological and neurodegenerative disorders is still warranted. This experiment seeks to build a system comparing pro-saccades, gap saccades, and overlap saccadic eye movements.

Corrective saccades: Effect of shifting the saccade goal
Vision Research, 1982A double step paradigm was used to investigate the saccade control, in particular the role of retinal feedback on correction saccades. The first target step eliciting the primary saccade had an amplitude of 10-15 deg and was followed by a second target step of 3 deg which occurred 0-300 msec after the onset of the primary saccade.

Exploring and targeting saccades dissociated by saccadic adaptation
Brain Research, 2011Saccadic adaptation maintains saccade accuracy and has been studied with targeting saccades, i.e. saccades that bring the gaze to a target, with the classical intra-saccadic step procedure in which the target systematically jumps to a new position during saccade execution.

Fixation and saccade control in an express-saccade maker
Experimental Brain Research, 1996In express-saccade makers a large incidence of express saccades (latencies around 100 ms) is paralleled by a reduced ability to suppress saccade generation when required. Such a behavior occurs frequently in dyslexics. We studied the latencies and the metrical properties of saccades in the very rare case of an adult, nondyslexic express-saccade maker ...

The aftermath of horizontal saccades: Saccadic retraction and cyclotorsion
Vision Research, 1986During horizontal saccades from either nasal or temporal direction, the eye is retracted into its orbit (about 100 micron for 8 degrees saccades), presumably due to co-contraction of the recti. That translational displacement of the eye thereafter slowly decays, with a half-time of about 100 msec.

Saccadic adaptation shifts the pre-saccadic attention focus
Experimental Brain Research, 2005The well-documented phenomenon of the spatial coupling between saccadic programming and the orienting of attention refers to the fact that visual attention is directed toward the location that the eyes are aiming for. However, the question remains open as to whether saccades and attention are two independent processes that can be directed concurrently ...
