Saccadic Facilitation in Natural Backgrounds
In visual systems with a fovea, only a small portion of the visual field can be analyzed with high accuracy. Saccadic eye movements shift that center of gaze around several times a second. Saccades have been characterized in great detail and depend critically on a number of visual properties of the stimuli. However, typical experiments have used bright spots on dark backgrounds, while our natur...
متن کاملSaccadic facilitation by modulation of microsaccades in natural backgrounds
Saccades move objects of interest into the center of the visual field for high-acuity visual analysis. White, Stritzke, and Gegenfurtner (Current Biology, 18, 124-128, 2008) have shown that saccadic latencies in the context of a structured background are much shorter than those with an unstructured background at equal levels of visibility. This effect has been explained by possible preactivatio...

متن کاملSaliency and saccade encoding in the frontal eye field during natural scene search.
The frontal eye field (FEF) plays a central role in saccade selection and execution. Using artificial stimuli, many studies have shown that the activity of neurons in the FEF is affected by both visually salient stimuli in a neuron's receptive field and upcoming saccades in a certain direction. However, the extent to which visual and motor information is represented in the FEF in the context of...
متن کاملTemporal Stability and the Effects of Training on Saccade Latency in “Express Saccade Makers”
The temporal stability of saccade latency, and the effects of training, particularly in "express saccade makers" (ESMs), has received little attention. ESMs are healthy, naïve, adults, who persist in executing very many low latency "express saccades" (ES; saccades with latency of 80 ms to 130 ms), in conditions designed to suppress such responses. We investigated the stability of ES production ...
