Hi Bluesky! Happy to share my PhD work: Spatial information was consistently represented across tasks in a low-dimensional subspace of PFC activity, while task identity was encoded in an orthogonal subspace, providing a stable and independent representation of context. doi.org/10.1101/2025...

Do you work on surface MRI such as HCP data? Our paper is finally out in Imaging Neuroscience, showing biases in surface fMRI. The revised ms has many new insights! TLDR: Vertices are much closer to each other in sulci, resulting in (fake) high spatial autocorrelation. (1/5)

Curious about the history of the manifold/trajectory view of neural activity. My own first exposure was Gilles Laurent's chapter in "21 Problems in Systems Neuroscience", where he cites odor trajectories in locust AL (2005). This was v inspiring as a biophysics student studying dynamical systems...

This was always going to be the outcome. Private universities with large endowments can cushion the blow, state universities without a large donor base will be left to wither. The rich get richer, everyone else is left to die. It is, at its core, simply age-old Republican politics at work.

New paper alert! Have you ever looked at single-trial fMRI activation maps? If so, you know that they are super variable. Here we show that the variability is not just noise. In fact, the same task can consistently elicit different activation patterns. www.nature.com/articles/s41...

Must watch speech by neuroscientist Kailyn Price at a HHS rally protesting funding cuts to science. "Cutting indirect costs is like telling a football team to work with only the players. No lights for the field, no physical therapists for the players, no water for the showers."

HOT OFF THE PRESS - Back in 2019 we started asking ourselves what could you to demonstrate where werable, OPM-MEG technology could fit into naturalistic #neuroskyence. One snag, we'd have to build the system from scratch first... Anyway its 2025, read the paper here -> doi.org/10.1162/imag...

Universities in Canada are being gutted because politicians wanted to blame them for societal ills. The attack in the USA is more direct and dire. But it has been happening here too. As Canada rises to the current challenges, we should invest in Canadian innovation, invest in our Universities.

Can LLMs be used to discover interpretable models of human and animal behavior?🤔 Turns out: yes! Thrilled to share our latest preprint where we used FunSearch to automatically discover symbolic cognitive models of behavior. 1/12
