“…The ϳ10-fold difference between the preferred linear and nonlinear spatial frequencies we found in the cat LGN and others have reported in cat area 18 (Mareschal and Baker, 1999) also appears consistent with the responses of both primate parasol cells (Crook et al, 2008a) and LGN Y-cells (Gielen et al, 1981). Y-like cells may thus underlie sensitivity to non-Fourier features in the primate visual system (Petrusca et al, 2007;Rosenberg and Talebi, 2009). …”

“…Neurophysiology studies have demonstrated that cortical neurons responding to CM stimuli exhibit selectivity for the carrier that is similar to the selectivity of nonlinear subunits of subcortical Y-cells [13][14][15] . These results support the idea that cortical CM responses are critically dependent on Y-cell inputs 14,16,17 .…”

Retinal ganglion cells (RGCs) initiating the magnocellular/Y-cell visual pathways are distinguished by responding nonlinearly to high spatial frequencies (SFs) and temporal frequencies (TFs). This nonlinearity is implicated in the processing of contrast modulation (CM) stimuli in cats and monkeys, but its contribution to human visual perception is not well understood. Here we formulated an approach to reveal the function of human Y-like RGCs by leveraging the Y-like carrier response properties of cortical neurons to CM stimuli consisting of a high SF contrast-reversing grating carrier whose contrast is modulated by a low SF drifting sinewave envelope. Subjects reported the direction of motion of CM envelopes or luminance modulation (LM) gratings, presented at different eccentricities. The dependence of task performance on SF (for LMs) or carrier SF (for CMs) was measured for different TFs (LMs) or carrier TFs (CMs). The best performance for LM stimuli was at lower TFs and SFs, which decreased systematically with eccentricity. However, performance with CM stimuli was bandpass with carrier SF, largely independent of carrier TF, and at the highest carrier TF (20 Hz) decreased minimally with eccentricity. Since the nonlinear subunits of Y-cells respond better at higher TFs compared to the linear response components, and respond best at higher SFs that are relatively independent of eccentricity, these results suggest that behavioral tasks employing CM stimuli with high spatiotemporal carrier frequencies can reveal the nonlinear contributions of retinal Y-like cells to human perception.

“…Although αRGCs have been identified across many species, there are some differences between species. In the primate retina, On and Off parasol cells, originally described by Polyak [ 53 ] (for review, see [ 54 ]), are the closest homologues of the cat αRGCs [ 55 – 57 ]. Similarly as in the cat retina, only one paramorphic pair (On and Off parasols) has been found in the primate retina.…”

Visually guided behaviour at its sensitivity limit relies on single-photon responses originating in a small number of rod photoreceptors. For decades, researchers have debated the neural mechanisms and noise sources that underlie this striking sensitivity. To address this question, we need to understand the constraints arising from the retinal output signals provided by distinct retinal ganglion cell types. It has recently been shown in the primate retina that On and Off parasol ganglion cells, the cell types likely to underlie light detection at the absolute visual threshold, differ fundamentally not only in response polarity, but also in the way they handle single-photon responses originating in rods. The On pathway provides the brain with a thresholded, low-noise readout and the Off pathway with a noisy, linear readout. We outline the mechanistic basis of these different coding strategies and analyse their implications for detecting the weakest light signals. We show that high-fidelity, nonlinear signal processing in the On pathway comes with costs: more single-photon responses are lost and their propagation is delayed compared with the Off pathway. On the other hand, the responses of On ganglion cells allow better intensity discrimination compared with the Off ganglion cell responses near visual threshold.This article is part of the themed issue ‘Vision in dim light’.
