Want to come do a postdoc with us?

We’re interested in how sensorimotor function is carried out by the cells and circuits of the spinal cord. We have an awesome team, lots of cool techniques, and we’re open to new ideas/approaches/connections. Get in touch!

This moment in history provides us with incontrovertible evidence that all the conservatives who claim to be extremely devoted to freedom of speech and the right to bear arms, and opposed to the encroachment of tyranny, are completely and totally full of shit.

It's all white supremacy and greed.

Dynamic engagement of the motor cortex in controlling movement Neural circuits do not contribute equally or continuously to behavior. In mice, the motor cortex can be essential or dispensable for movement in different contexts, but how it is dynamically recruited...

Very excited to share a new preprint - my first paper in the @mikeeconomo.bsky.social lab where we asked when and why the motor cortex is recruited for movement control:🧠👇https://www.biorxiv.org/content/10.64898/2026.01.13.699314v1

Ontogeny of the spinal cord dorsal horn The dorsal horn of the mammalian spinal cord is organized into laminae where each layer is populated by different neuron types, has distinctive circuit connections, and plays specialized roles in beha...

Excited to share @rbrianroome.bsky.social ‘s beautiful paper on development of the dorsal horn of the mouse spinal cord @science.org

This is how the anatomical organization and cell types that process pain, touch, body position and more are laid down.

This head is spinning continuously, but we see it rotating back and forth...

...presumably because of our strong prior expectation that faces are convex.

This is a very nice example of the Hollow-Face illusion promoted by Richard Gregory:

How to Get Rid of "Citizens United" We can do away with it without a new Supreme Court. Nor do we need a constitutional amendment. There’s a far simpler way.

If you’re looking for something to do, start working on overturning citizens united in your state. States control the power corporations have. Take their political power away with a ballot initiative. Here’s how: open.substack.com/pub/robertre...

To study how animals understand the physical world (and the rules that govern its dynamics), @jinyao-y.bsky.social trains rats to play fetch with robots 🐀🤖🎾

I am thrilled to share our latest work: we identified a population of central amygdala neurons that promote the earliest and perhaps most important social behavior: pup suckling!... We also developed new tools for pup neuroscience

1. Federal funding for research promotes tech, biomedical, and scientific discovery in the US, and provides training for the sci/tech workforce that has brought immeasurable wealth to the US over the past 75 years.

New Trump EO: "when ideological biases or social agendas are built into AI models, they can distort the quality and accuracy of the output"

...so henceforth the US government won't do business with you unless your LLM is built to echo our ideological bias and promote our social agenda.

Breaking the jar: Why NeuroAI needs embodiment Brain function is inexorably shaped by the body. Embracing this will benefit computational models of real brain function and the design of ANNs.

Embodiment is the concept that the function of the brain is inexorably shaped by the body, a lens that is often neglected when neuroscientists study specific brain subsystems, write @bingbrunton.bsky.social and @tuthill.bsky.social.

Stunning! An 8-hour time-lapse to show the Earth is rotating while capturing the Milky Way.

Fear and loathing on study section: Reviewing grant proposals while the system is burning As grants are canceled, delayed and subject to general uncertainty, participating in study sections can feel futile. But it’s more important than ever.

Single-neuron projectome reveals organization of somatosensory ascending pathways in the mouse brain Ding et al. mapped a single-cell projectome of 785 spinal projection neurons and 1,464 central relay neurons in thalamus, hypothalamus, PB, SCm, PAG, and medulla. They have constructed a high-resoluti...

Some really nice single-neuron tracing here, highlighting the diversity of potential loops between brain and cervical spinal cord. Mostly consistent with previous results from bulk axon labeling, but with more detail about collaterals and all in one place for synthesis: www.cell.com/neuron/fullt...

Can your AI beat a mouse?

Mice still outperform our best computing machines in some ways. One way is robust visual processing.

10 years ago I decided to work on HARD behavior driven by COMPLEX visual processing. And that risk is paying off now. #neuroAI 1/n

Inspired by Francis Collins on guitar and all the wonderful speakers at Stand Up For Science DC today. Keep it up!

Crowd at Lincoln memorial

The @standupforscience.bsky.social DC rally is on.

What we are hearing from around the country:
"this is big!"
"biggest rally I have seen around here in years and years"

The public cares about medical research--and students, GenZ, and other people too are ready to stand up.

It Was an Ambush Today marked one of the grimmest days in the history of American diplomacy.

“Today’s meeting confirmed that the US is now aligned with Russia and against Ukraine, Europe, and most of the planet. I felt physically sick watching the president yell at a brave ally…”
