Modeling spatial contrast sensitivity in responses of primate retinal ganglion cells to natural movies

The paper develops a spatial contrast model to capture nonlinear spatial integration in primate retinal ganglion cells using natural and artificial stimuli, showing improved performance over linear models.

Spatial Adaptation of Primate Retinal Ganglion Cells between Artificial and Natural Stimuli

This study examines how primate retinal ganglion cells adapt their spatial processing to natural versus artificial stimuli, finding that some cell types adjust receptive fields and surrounds, but efficient coding only partially explains these changes.

Applying Super-Resolution and Tomography Concepts to Identify Receptive Field Subunits in the Retina

This paper introduces STR, a method combining super-resolution and tomography to identify receptive field subunits in retinal ganglion cells, validated in primate recordings.

Accelerated spike-triggered non-negative matrix factorization reveals coordinated ganglion cell subunit mosaics in the primate retina

The paper introduces an accelerated version of spike-triggered non-negative matrix factorization to identify coordinated subunit mosaics in primate ganglion cells.

A systematic comparison of predictive models on the retina

This study compares predictive models for retinal ganglion cell responses, finding that CNNs outperform LN models, while LN models show better cross-stimulus generalization.

Diversity of Ganglion Cell Responses to Saccade-like Image Shifts in the Primate Retina

The paper investigates how primate retinal ganglion cells respond to saccade-like image shifts, revealing distinct response patterns and functional diversity among cell types.

The self-organized learning of noisy environmental stimuli requires distinct phases of plasticity

The paper shows that learning noisy environmental stimuli requires two distinct phases of plasticity: one for encoding stimulus organization and another for readaptation to noise levels.
