Exploring and explaining properties of motion processing in biological brains using a neural network

This paper trains a neural network to estimate motion velocity and finds it recapitulates biological motion processing characteristics and human perceptual biases.

Testing for functional organization of three-dimensional surface tilt encoding within visual cortex

The paper tests if 3D surface tilt is functionally organized in visual cortex using fMRI and finds pinwheel-like tilt preference structures in V3A and V7.

Adaptation to binocular anticorrelation results in increased neural excitability

The paper investigates how neural adaptation to binocular anticorrelation affects neural excitability using SSVEPs in humans.

Mixed-polarity random-dot stereograms alter GABA and Glx concentration in the early visual cortex

The paper measures GABA and Glx concentrations in the early visual cortex during viewing of single- and mixed-polarity random-dot stereograms, finding lower GABA and higher Glx with mixed-polarity stimuli.

Contextual effects on binocular matching are evident in primary visual cortex

The paper shows that global context influences binocular depth perception in primary visual cortex (V1) using fMRI and multi-voxel pattern analysis.
