You know what? For €25, this is not a bad way to add a digital read-out to a stereotaxic frame. I'm measuring about a 20 micron discrepancy per millimeter between the DRO and the stereotax; not terrible. #neuroSkyence 🧠

My lab is looking for an intern interested in the molecular basis of cognitive decline. Work includes deep phenotyping of animal behavior and downstream analysis, including DLC tracking, motif mining (e.g. with Keypoint-MoSeq), and -omics. On-site at EMBL Rome, paid, 1-year commitment. DMs open.

Baseline activity of V1 interneurons connects pupil-linked arousal to engaged behavioral state https://www.biorxiv.org/content/10.64898/2026.02.05.704022v1

We could all use some extra stress #resilience rn. But how does it work in the brain? On the surface, resilience looks like ignoring stress. Does the brain fail to respond? Or are active adaptations required? Or are resilience and susceptibility divergent paths? doi.org/10.1016/j.celrep.2025.116867

Psychophysics is a human-facing science with interventions arguably more robust than medicine.

Planning a one-afternoon visual psychophysics practical for undergraduate students. Does anyone know a good platform to collect quantitative data on visual acuity, the blindspot, colour mixture, depth perception, edge detection, lateral inhibition, motion adaptation, visual illusions etc?

Thrilled this is out, led by former PD Cameron Ogg (now with her own lab at @rhodescollege.bsky.social!). It was a driven by a desire to see, in real-time, how LC activity/NE release influences downstream targets in behaving animals. SO hard to do, but Cameron did it! www.cell.com/cell-reports...

Research in primate brains has been essential for the development of brain-computer interfaces and artificial neural networks. New funding and policy changes put future such advances at risk, write Cory Miller, @movshon.bsky.social and Doris Tsao. #neuroskyence bit.ly/47MXYLH

Still think brain regions don’t exist? That everything is everywhere? That cell types don’t matter and that everything is a dynamical phase portrait? Wrong. Interconnected brain modules exist at the level of fine grained transcriptomics. www.nature.com/articles/s41...

In the early years of my PhD I remember being asked if we'd ever treat or cure diseases like HIV or Huntington's. I remember saying maybe, but not knowing if I believed. Seeing research pay off as real impact on human lives is - incredible. www.bbc.com/news/article... www.bbc.com/news/article...

You could have rather put the quotation marks in "arousal", given the last sentence of the paper. Nice and impressive, but it's basically saying that there is a low-dimensional descriptor. Now, it could have been reversed having latent brain dynamics as a predictor, and pupillometry as the target

Super proud of this collaboration with rockstar Ryan Raut - born out of playing in the sandbox in our last year of grad school! Multi-scale brain activity can be predicted from a simple measure of arousal like pupil diameter. Out with linear causality, in with dynamic systems to explain neurobiology

This one looks intriguing. Arousal "embedding" whole-brain dynamics. 🤯 #neuroskyence #compneurosky doi.org/10.1038/s415...

It’s been a 24 hour traveling day from Portland to Pécs, which includes 2 planes, a bus, a metro, a train & a car. I am so excited to be at ERM2025 and to be selected as a speaker in the New Perspectives, Tools and Resources session!

Heroic experiments recording in SC and V1 in unrestrained animals to see how the two areas differentially respond to visual detection (with causal perturbation)

Cool study showing the LC has dopaminergic as well as norepinephrine release differentially in different circuits--relevant to our understanding of how arousal shapes responses throughout the brain

🚨New preprint alert! The thalamus has long been seen as a relay of sensory signals to cortex. But could it also generate its own structured activity? Our study explores this question in the head-direction (HD) system. Some explanation 🧵👇 1/13 www.biorxiv.org/content/10.1...

Thrilled to share that our work is now published in Science! ✨ We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭 www.science.org/doi/10.1126/... 🧵1/

We talked about this back when the first trial for lenacapavir first said the magic words everyone wants to hear, "halted for efficacy"(*), so a recap: this is not a vaccine or a treatment. It's PrEP aka "pre-exposure prophylaxis": you take the drug so if exposed to the virus, you will not catch it.
