there is a face in the center of the drosophila ellipsoid body diagram in Figure 17b of Hulse et al 2022(iiif.elifesciences.org/lax:66039%2F...). who is it? is this an easter egg?

New paper out at PNAS: www.pnas.org/doi/10.1073/... Revisiting the high-dimensional geometry of population responses in the visual cortex with @jpillowtime.bsky.social. The review took forever because a reviewer was doubtful our new estimator can infer eigenvalues beyond the rank of the data! (1/6)

That image is from 1961 and an idealization. Here is an actual trajectory of fixational eye movements. The dots are 2 ms apart. If a midget ganglion cell, with single-cone receptive field, fires at 100 Hz, then every spike reports about a different cone. How can we ever read anything?

How do we get more neuroscience out of our behavioral data? Excited to share new work with C.A.Baker, M.Murthy and @jpillowtime.bsky.social, where we use natural behavior data to extend predictions from neural recordings about population codes for dynamic social stimuli: tinyurl.com/2d3wwfyf

Someone please do this with a neuroscience foundation model. Start with known computations: reichardt detector in fly, inter-aural delay lines in owl, etc. @tyrellturing.bsky.social ?

Believe it a not, a third multisite connectomic project also lost funding. The multi-PI R01 led by @darbly.bsky.social with myself and @bassemh.bsky.social as co-PIs.

It’s almost 2025 and the US’s green card backlog for people born in China and India was still 2022 for EB-1 and 2020 for EB-2—visa categories that represent some of the most talented individuals on the planet.

In the present discussions about NIH and the need for reform, two recurring points I am seeing are: (1) NIH doesn't fund truly high impact research (2) NIH needs to experiment with alternative approaches to peer review, particularly for high risk-high impact research 1/n

More from inside NIH: Per a source with knowledge, for all internal research (of which there is like $10 billion worth or so), ALL purchasing shut down as of yesterday. That means gloves, reagents, anything involved with lab work, which means a lot of that work will stop.
