The Rod Bipolar Cell Pathway Contributes To Surround Responses In OFF Retinal Ganglion Cells Sensory neurons can be influenced by stimuli beyond their receptive field center, yet the mechanisms underlying this surround modulation remain poorly understood. In the retina, many OFF ganglion cell...

An array of 9 purple discs on a blue background. Figure from Hinnerk Schulz-Hildebrandt.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

Your red is my red, at least to our brains Despite philosophical debates, colors like red may spark similar brain activity across individuals, new research suggests.

“The results show that neural reactions to colors are somewhat standard and don’t seem to vary much from person to person. But these neuroanatomical findings can’t answer the question of how it feels to see red…”

Rapid Invisible Frequency Tagging (RIFT) with a consumer monitor: A proof-of-concept Rapid Invisible Frequency Tagging (RIFT) enables neural frequency tagging at rates above the flicker fusion threshold, eliciting steady-state responses to flicker that is almost imperceptible. While R...

🚨 New preprint: Invisible neural frequency tagging (RIFT) for the underfunded researcher:

RIFT uses high-frequency flicker to probe attention in M/EEG with minimal stimulus visibility and little distraction. Until now, it required a costly high-speed projector.

Why was Newton so sure that if you just did his optical experiments you’d *have* to believe him about light? Kirsten Walsh, Tom Roberts and I use 4E cognition to suggest an answer. Anachronism? You be the judge… (also i’m real proud of this paper) www.journals.uchicago.edu/doi/epdf/10.... #philsci

Enjoying this 1884 paper by CS Peirce and Joseph Jastrow on whether perception exhibits a hard threshold - the idea that as stimulus intensity increases, at some value it goes from unconscious to conscious, rather than following a smooth probabilistic curve. psychclassics.yorku.ca/Peirce/small...

Why can we decode visual mental contents from primary visual cortex when all evidence points at the absence of sustained spiking in this part of the brain? Today at #CCN25 poster C104, Noa will present a tentative answer from her work with attractor models. Wish I could’ve been there!

Delighted to share this paper, now published in @arvoinfo.bsky.social. With @spk3lly.bsky.social‬ and Anna Geuzebroek we explored differences in visual cortical responses for pattern pulses and pattern reversals. Here's the link:
