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?
Matthias Nau@matthiasnau.bsky.social · 9mo agoWhat a great figure! What we call “fixation” is really a complex pattern of fixational eye movements, several captured beautifully in this single shot. Love it! 👀 #EyeTracking www.nature.com/articles/nrn...
Thrilled to join UIUC as Prof of Computational Neuroscience! Lets figure the brain out before we're dead! Recruiting PhDs via CS, ECE & Psych. We study stats methods, mechanistic model inference (w/ connectomics), sensory coding & more. Reach out! deanp@illinois.edu
I've wanted to write this article for years. About my and other's struggles to even survive sometime in #academia. Thank you to the amazing editors at @plosbiology.org that gave me the forum to write this piece. #science
Too poor to science: How wealth determines who succeeds in STEM
From student to researcher, a career in science can come with a high price tag. This Perspective explores how persistent financial barriers limit who can succeed in science, revealing how wealth shape...

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 ?
Ted Underwood@tedunderwood.com · last yr.A different approach to interpretability. Instead of probing neurons and circuits, *tune* the models to provide "accurate, quantitative descriptions of their own internal processes during certain kinds of decision-making," and then show that this ability generalizes. #MLSky 🤖
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.
