Thanks and congrats!

To accompany my textbook (Computational Foundations of Cognitive Neuroscience) and the class I taught this semester, I'm open-sourcing my lectures slides:

I'll continue to update these as I improve them.

Going from neural activity to blood flow just became easier! Two brainwide populations, each with its neurovascular coupling. (But going backwards... is now a tad more complicated.)

Thanks @intlbrainlab.bsky.social @wellcometrust.bsky.social @simonsfoundation.org

Nice summary of our recent work on neural population geometry and generalization across multiple tasks with shared latent structure.

Thank you @natmesanash.bsky.social and @thetransmitter.bsky.social for the great article!

Dorsal Raphe Revisited: A Systems Neuroscience Lens on Psychedelic Drug Action - Alex C. Kwan, 2026 Psychedelics rose to prominence in the 1960s, around the same time when neurobiologists identified the midbrain raphe as the brain’s primary source of serotonin...

For those interested in the history of psychedelic research…

I wrote a narrative piece describing studies of psychedelic effects on serotonergic neurons in the dorsal raphe, from late 1960s to 1980s:

Functional synaptic connectivity shapes spine stability in the hippocampus - Nature Communications In this study, the authors find that synaptic strength predicts spine size and long-term stability via in vivo imaging together with optogenetic stimulation in awake mice. While individual synapses sh...

Entorhinal cortex represents task-relevant remote locations independently of CA1 - Nature Neuroscience Neurons in medial entorhinal cortex collectively represent discrete nonlocal positions during immobility. During this nonlocal coding, CA1 is uncoupled from entorhinal cortex. These representations ar...

Stoked this is finally out! We ask: how can we simulate the brain from the bottom up? It's not sufficient to grab the connectome and wire it up in silico! We need 1) ultrastructure 2) (causal) calibration data 3) functional data. Then we can build a simulation compiler. 1/

Episode #39 in #TheoreticalNeurosciencePodcast:
On modeling neural population activity with mean-field models – with Tilo Schwalger

How can mean‑field models be systematically derived from the underlying microscopic dynamics of individual neurons?

An important piece on error-based learning in biological networks

We've created a tool to visualize the map of electric signals (LFPs) in the whole mouse brain. Different brain areas have electrical fluctuations that look more like a select number of areas, thus creating a map.

Linking neural manifolds to circuit structure in recurrent networks Neural population activity can be described either by low-dimensional dynamics on neural manifolds or by single-neuron selectivities. Using a theoretical approach, Pezon et al. relate these two statis...

Quite impressed with the results reported here, a cerebellar learning signal affects neocortex plasticity. In the context of credit assignment, this suggest a cross-system coordination of plasticity: elifesciences.org/articles/109...

I recommend this school to anyone interested in computation in the brain - it receives excellent reviews year after year, it is highly interactive and social, and the setting is remarkable.

New paper alert! 🚨

We found that the brain's compass is remarkably stable at two scales

1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit

This may be key to how the brain aligns its other maps.
