IONS

In a dynamic environment, human subjects often make anticipatory eye movements to shift the visual axis towards the position where a stimulus of interest is likely to appear next. However, anticipation has to adapt to the inherently stochastic nature of physical events that can impact cognitive control and be psychologically distressing. Moreover, anticipatory actions require to keep track of elapsed time and inhibitory control. These cognitive functions could be impacted in neuropsychiatric diseases like Parkinson's.
