Introduction: Numerous previous studies have shown that eye movements induce errors in the localization of briefly flashed stimuli. Remarkably, the error pattern is indicative of the underlying eye movement and the exact experimental condition. For smooth pursuit eye movements (SPEM) and the slow phase of the optokinetic nystagmus (OKN), perceived stimulus locations are shifted in the direction of the ongoing eye movement, with a hemifield asymmetry observed only during SPEM.

- Juvenile myoclonic epilepsy (JME) can cause emotional issues and problems in making friends, linked to brain circuit problems.
- Researchers studied how these brain circuits work when people feel empathy for others' pain by using special brain scans and eye tests on 15 JME patients and 15 healthy people.
- They found that JME patients didn’t activate certain brain areas as much when feeling empathy, and their eye responses were also different, showing how this affects their ability to connect with others.
Purpose: To assess the reproducibility of brain-activation and eye-movement patterns in a saccade paradigm when comparing subjects, tasks, and magnetic resonance (MR) systems.
Materials And Methods: Forty-five healthy adults at two different sites (n = 45) performed saccade tasks with varying levels of target predictability: predictable (PRED), position predictable (pPRED), time predictable (tPRED), and prosaccade (SAC). Eye-movement pattern was tested with a repeated-measures analysis of variance.
Spatial perception is modulated by eye movements. During smooth pursuit, perceived locations are shifted in the direction of the eye movement. During active fixation, visual space is perceptually compressed towards the fovea.
