This study identifies brain regions in humans that maintain a consistent directional representation during naturalistic virtual navigation.

This study investigates the photoreceptor basis of light avoidance in mice and shows that CGRP sensitization enhances ipRGC-mediated light avoidance.

This study measures light exposure in youth with migraine using wearable devices and finds phase shifts in light exposure patterns between chronic and non-chronic migraineurs.

The paper shows that the tilt illusion results from increased neural coding precision for stimuli similar to an oriented surround, using psychophysical and fMRI data from humans.

The paper measures temporal dynamics of human color processing using a tracking task and finds similar elliptical response contours for detection and tracking, but reduced sensitivity to S-cone signals in tracking.

The paper shows that the structure of a temporal sequence affects how well stimuli are represented in the brain, with modular graphs leading to better prediction and higher dimensionality in visual areas.

This study measures temporal sensitivity of visual cortex responses to achromatic and chromatic flicker stimuli across different cortical areas and eccentricities.

The paper uses fMRI to assess cone-driven responses in canine retinal disease models, finding preserved responses in some models and restored function in NPHP5-CRD2 after gene augmentation.

This study develops a parametric model linking trigeminal nerve stimulation intensity to blink response properties, finding a laterality effect in half-response thresholds.

The paper finds that retinal ganglion cell endowment correlates with optic tract cross section, not density, and that anatomical variations are locally correlated along the visual pathway.

This study characterizes MR-induced nystagmus in resting state HCP data at 3T, finding persistent horizontal and vertical eye movements with no significant adaptation.

This study investigates whether melanopsin stimulation affects sensitivity to luminance flicker and finds no significant effect.

The paper assesses the role of ipRGCs and cones in reflexive eye closure as a measure of photophobia in migraine, finding enhanced responses in MwA compared to other groups.

The paper develops a quadratic color model (QCM) to explain human V1 BOLD fMRI responses to chromatic direction and contrast variations, finding it matches a GLM with fewer parameters.

FlywheelTools provides software for reproducible data curation and manipulation on the Flywheel platform, addressing challenges in converting neuroimaging data to BIDS format.

This paper uses PCA to analyze prVEP data across developmental ages, revealing age and sex-related changes in visual evoked potential patterns.

This paper presents a physically accurate model of the human eye's appearance during movement, enabling the estimation of eye pose and biometric parameters from images.

The paper examines how axial length affects retinal ganglion cell layer thickness and volume, finding a positive relationship between axial length and GCL tissue volume.

QSIPrep is a software platform for preprocessing diffusion MRI data that supports multiple sampling schemes and ensures reproducibility through standardized workflows and quality measures.

The paper links increased visual cortical activation to visual discomfort from flicker by measuring neural responses and discomfort ratings in migraineurs and controls.

This study investigates how melanopsin and cone signals contribute to photophobia in migraine and finds that migraineurs amplify ipRGC signals specifically for discomfort, not pupil responses.

This paper presents a ray-traced model of the human eye's entrance pupil that accurately reproduces empirical measurements of its shape.

The paper examines how individual differences in response precision correlate with adaptation bias in perceptual tasks using a Bayesian framework.

This study measures pupil responses to melanopsin-directed contrast pulses and finds they are reliable and insensitive to background radiance changes.

The paper tests if visual adaptation decorrelates shape representations in humans using behavioral and fMRI experiments, finding improved discrimination and decorrelation in object-selective cortex.

The paper predicts future motor learning from baseline sensorimotor network connectivity in humans.

The paper investigates the perceptual effects of melanopsin-directed stimulation and finds a distinct cortical response and conscious percept.
