Biophysical neural adaptation mechanisms enable artificial neural networks to capture dynamic retinal computation Open
Adaptation is a universal aspect of neural systems that changes circuit computations to match prevailing inputs. These changes facilitate efficient encoding of sensory inputs while avoiding saturation. Conventional artificial neural networ…

Dependence of perceptual saccadic suppression on peri-saccadic image flow properties and luminance contrast polarity Open
Perceptual detectability of brief visual stimuli is strongly diminished across saccades. Recent work showed that this perceptual suppression phenomenon is jumpstarted in the retina (Idrees et al., 2020), suggesting that the phenomenon migh…

Saccadic suppression by way of retinal image processing Open
Humans make eye movements such as saccades four times every second. Saccades disrupt the visual flow on the retina; however, visual perception remains a stable and coherent process. This is a striking achievement of the visual system. Visu…

Across saccades, perceptual detectability of brief visual stimuli is strongly diminished. We recently observed that this perceptual suppression phenomenon is jumpstarted in the retina, suggesting that the phenomenon might be significantly …

Different contrast encoding in ON and OFF visual pathways Open
Subjective visual experience builds on sensory encoding of light reflected by different objects in our environment. Most retinal ganglion cells encode changes in light intensity, quantified as contrast, rather than the absolute intensity. …

Suppression without inhibition: How retinal computation contributes to saccadic suppression Open
Visual perception remains stable across saccadic eye movements, despite the concurrent strongly disruptive visual flow. This stability is partially associated with a reduction in visual sensitivity, known as saccadic suppression, which alr…

Perceptual saccadic suppression starts in the retina Open
Visual sensitivity, probed through perceptual detectability of very brief visual stimuli, is strongly impaired around the time of rapid eye movements. This robust perceptual phenomenon, called saccadic suppression, is frequently attributed…

Selective peri-saccadic suppression of low spatial frequencies is a visual phenomenon Open
Visual sensitivity is strongly impaired around saccades, a phenomenon known as saccadic suppression. This robust phenomenon does not constitute a mere global suppression, but instead shows selectivity for low spatial frequencies, which has…

Extra-retinal mechanisms as compensation for retinal-circuit-level visual masking effects in saccadic suppression Open
Perceptual suppression occurs robustly around saccades, but its underlying mechanisms are debated. On the one hand, purely visual masking effects may be sufficient; on the other, pathways for extra-retinal saccade-related corollary dischar…

Alteration of the microsaccadic velocity-amplitude main sequence relationship after visual transients: implications for models of saccade control Open
Microsaccades occur during gaze fixation to correct for miniscule foveal motor errors. The mechanisms governing such fine oculomotor control are still not fully understood. In this study, we explored microsaccade control by analyzing the i…
