Some uniquely human nerve circuits for color vision allow people to perceive a greater range of blue tones than monkeys do. @PNASNews study by Yeon Jin Kim @RetinaVision @Dacey_Lab @BioStructureUW & colleagues @SydneySaveSight et al bit.ly/3ABq1gH
Bulb-like axon terminals of cone photoreceptors in the marmoset’s foveal retina. The blue pedicle, a short wavelength sensitive neuron, gives rise to complex circuitry that starts a neural code for color perception. Image by Yeon Jin Kim @retinavision @Dacey_Lab @BiostructureUW @PNASNews

By contrast there is physiological evidence for a second blue-ON cell type referred to morphologically as the "large bistratified ganglion cell" : sciencedirect.com/science/ar…

New paper in @CurrentBiology! We find a new, unexpected blue/S-cone neuron: M2 ipRGCs. Their Blue-ON input challenges coding hypotheses underlying classic color vision models & establishes a new short-wavelength input to non-image-forming vision @jay_neitz cell.com/current-biology/ful…

If there was an S-ON input to the Melanopsin expressing ganglion cells in macaque retina I think it would have been observed in this study measuring cone inputs to these cells with physiological methods: nature.com/articles/nature03…
