Well, that's a quick read Gaia!
Congrats @gaiabianchini.bsky.social @flor-iacaruso.bsky.social & Co on this beast of a study and welcome to the less-bad place 💪🎉

We presented visual and auditory stimuli at different time intervals to mice while recording superior colliculus activity. We found diverse multisensory neurons, many integrating AV signals nonlinearly based on timing—these are multisensory delay-tuned neurons.

We tested how nonlinear integration affects sensory encoding by comparing real vs. synthetic responses (where AV signals were linearly added). The result? Nonlinear integration preserves precise AV timing, while linear addition severely reduces decoding accuracy.

Decoding of AV timing was most precise in colliculus regions encoding the visual periphery. This may enhance responses to unattended stimuli - crucial function for survival.

Very interesting paper! I think the figure 6 caption is erroneously labelled figure 3 in the biorxiv version
