Degraded mapping of disparity tuning in visual cortex explains deficits in binocular depth perception Open
Sensory cortex is highly organized, but understanding why remains elusive. Here we demonstrate that depriving juvenile mice of vision in one eye during the critical period for the development of binocularity (monocular deprivation) caused …

Fluctuating internal states mediate neural-behavioral covariations in V1 Open
Our perception of the world depends on a complex interplay between external sensory inputs and our internal states. How and where in the brain the interactions between internal states and sensory inputs are implemented remain open question…

Mammals Achieve Common Neural Coverage of Visual Scenes Using Distinct Sampling Behaviors Open
Most vertebrates use head and eye movements to quickly change gaze orientation and sample different portions of the environment with periods of stable fixation. Visual information must be integrated across fixations to construct a complete…

Mammals achieve common neural coverage of visual scenes using distinct sampling behaviors Open
Most vertebrates use head and eye movements to quickly change gaze orientation and sample different portions of the environment with periods of stable fixation. Visual information must be integrated across several fixations to construct a …

Disparity Tuning PDCT Open
Disparity tuning fits, preferred disparities, and disparity (d) used for neuronal discrimination analysis. Variable with "t" at the end are only those neurons with statistically significant disparity tuning. Variable without the "t" are al…

Mice Discriminate Stereoscopic Surfaces Without Fixating in Depth Open
Stereopsis is a ubiquitous feature of primate mammalian vision, but little is known about if and how rodents such as mice use stereoscopic vision. We used random dot stereograms to test for stereopsis in male and female mice, and they were…

Motion Discrimination and the Motion Aftereffect in Mouse Vision Open
Prolonged exposure to motion in one direction often leads to the illusion of motion in the opposite direction for stationary objects. This motion aftereffect likely arises across several visual areas from adaptive changes in the balance of…

Nonuniform surround suppression of visual responses in mouse V1 Open
Complex receptive field characteristics, distributed across a population of neurons, are thought to be critical for solving perceptual inference problems that arise during motion and image segmentation. For example, in a class of neurons r…

Binocular alignment in mice during stereoscopic discrimination of depth Open
In order for animals with binocular vision to use retinal image disparity to infer depth, they must be able to maintain some alignment between the eyes. Primates and carnivores frequently make coordinated saccades, and when they fixate on …

Evidence of Stereoscopic Surface Disambiguation in the Responses of V1 Neurons Open
For the important task of binocular depth perception from complex natural-image stimuli, the neurophysiological basis for disambiguating multiple matches between the eyes across similar features has remained a long-standing problem. Recurr…
