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?

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

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

Social communication between animals is often mediated by sequences of acoustic signals,
sometimes spanning long timescales. How auditory neural ci...

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 ?
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 🤖
Self-Interpretability: LLMs Can Describe Complex Internal Processes that Drive Their Decisions, and Improve with Training
We have only limited understanding of how and why large language models (LLMs) respond in the ways that they do. Their neural networks have proven challenging to interpret, and we are only beginning t...

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.
Two multisite projects aimed at scaling up mouse connectomics lost federal funding in recent cuts to Harvard University grants.

Multisite connectome teams lose federal funding as result of Harvard cuts
The teams aim to develop tools to scale up mouse connectomics in preparation for eventually mapping an entire human brain.

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

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.

Please consider turning on the sound for this post. The sniffs & spikes are sonified by converting the event times to MIDI.
Kick drum=inhalation times
Piano=spike times, where each note signifies the spike of a given unit
(code & preprint on the method soon)

Sniffing helps animals identify smells and connect them to places and events, but noses can’t sense time or place.
How do brains connect odors with internal models of the world?
Our preprint suggests that the olfactory bulb participates in this connection.
