New results showing that an inevitable, unadaptable, and extremely short-latency behavioral reflex is an exclusively cortical phenomenon.

New article with our Tübingen neuroscience colleagues, identifying common principles across vastly different species and sensory-motor modalities.

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 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.

🍾Big congratulations to Matthias P. Baumann @MatthiasPhilip6 from the Lab of Ziad Hafed @HafedLab. After winning the "HIH Paper of the Year Award" this summer, he now received the Attempto Prize. Amazing work 👏
