New paper by the lab: superior colliculus eye movement commands simultaneously sense the visual appearance of the environment.

The superior colliculus exhibits qualitatively similar visual responses to those in the primary visual cortex. We show that this similarity masks a large fundamental difference between the two areas when it comes to active vision:.

New paper about foveal visual representations in the superior colliculus, and how they may help integrate visual scene information across rapid eye movements.

Saccadic suppression was demonstrated in many species. In a new paper, using modeling and matched experimental paradigms in fish and primates, we explored the reasons for why saccadic suppression strength might be different in different organisms.

New paper establishing a novel paradigm for exploring the neurophysiological mechanisms underlying a well-known active vision phenomenon.

New paper: "prediction error" signaling by foveal superior colliculus neurons across eye movements. Could be one building block for maintaining perceptual stability despite disruptions of retinal image streams caused by eye movements.

New paper demonstrating saccadic suppression in zebrafish, as well as an intriguing selectivity for specific stimuli. In upcoming work, we'll also quantitatively compare the zebrafish suppression strength to that in primates.

New paper just out. We analyzed superior colliculus field potentials, and linked two surprising phenomena that we had previously described individually, and independently of each other.

New paper linking our interests in active vision, microsaccades, visual attention, sensory/motor brain structures, as well as visual processing asymmetries in the brain.

We said it in 2002, 2011, 2013, and then again during 2015-2018. now, we say it with compelling causal evidence: foveal action for the control of extrafoveal vision.

New results. We ported the 2-d perisaccadic perceptual mislocalization paradigm for use in neurophysiology experiments.

New paper on perisaccadic visual mislocalization.

New results. We knew that superior colliculus has higher visual sensitivity in the upper visual field (UVF), and visual feature tuning in motor bursts. Now we know that the UVF sensory preference locally persists peri-saccadically.

We previously discovered enhanced peripheral visual sensitivity for premicrosaccadic stimuli, and linked it to covert attention. Here, we describe a preferential "highlighting" of dark stimuli by the SC during premicrosaccadic epochs.

New observations demonstrating that perceptual mislocalization around the time of saccades depends on the visual appearance of the saccade targets.
