New preprint! We identified a mechanism for face processing that's centered on primate SC. It's freaky fast (faster than cortical face patches), depends on inputs from visual cortex (as opposed to retina), and explains some puzzles in the literature. #tweeprint below. 1/n

We are recruiting PhD students for this fall, to work at the interface of visual neurophysiology and machine learning. Are you enthusiastic (and ideally knowledgable :) about both? Send me an email!

This is a line in sand, a rallying cry, and a call to arms for anyone who has suffered under tyranny of the argument that the amygdala is “evolutionary conserved”. Never again do I want to hear the tired argument that a rodent amygdala, is a monkey amygdala, is a human amygdala.

Poster day! @gongchen_yu will show how primate SC exhibits short-latency (<40ms!) face preference, and I will show what happens to that preference (and in fact, **ALL** visual activity in SC) when LGN is inactivated. Side by side, X7 & X8, today 8am-noon #SfN2023. Come say hi

In summary, we identified an ultra-fast circuit mechanism for face detection that complements the slower (but more elaborate) face processing in temporal cortex. Additionally, our findings contradict the prevailing textbook assumption that retinal inputs drive SC visual responses
