- Reposted by Felix TaschbachWhen @natrevneuro.nature.com asked me to highlight a paper that influenced both my field and my own research, I immediately thought of the work on mixed selectivity by @matrig.net, @stefanofusi.bsky.social, and colleagues. More on this journal club: rdcu.be/eRKLk
- Reposted by Felix TaschbachY’all are reading this paper in the wrong way. We love to trash dominant hypothesis, but we need to look for evidence against the manifold hypothesis elsewhere: This elegant work doesn't show neural dynamics are high D, nor that we should stop using PCA It’s quite the opposite! (thread)
- Guess international students can't apply for a postdoc at MIT🙃

- Reposted by Felix TaschbachSuper excited to share the first cooperative foraging paradigm in freely interacting mouse pairs! Stable leader and follower roles emerge spontaneously and predict learning. Well-trained mice show stereotyped, role-specific “behavioral motifs” absent in naive animals (1/5) doi.org/10.1101/2025...
- Reposted by Felix TaschbachWe watched mice follow scent trails drawn on an “endless” treadmill. By manipulating trail geometry/statistics, perturbing mouse nose & brain, and modeling behavior with a Bayesian framework, we show that mice use predictive (rather than reactive) strategies.

- Reposted by Felix TaschbachThrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions. doi.org/10.1038/s415...
- Reposted by Felix TaschbachEver wondered what gives rise to efficient neural population geometry? Our lab’s new work, led by Sonica Saraf (w/ Tony Movshon), shows how diversity in single-neuron tuning shapes population-level representation geometries to improve perceptual efficiency. Congrats @sonicasaraf.bsky.social!
- In many brain areas, neuronal tuning is heterogeneous. But how does this diversity help behavior? We show how tuning diversity shapes representational geometry and boosts coding efficiency for perception in our new preprint: www.biorxiv.org/content/10.1... (w/ @sueyeonchung.bsky.social&Tony Movshon)
- Reposted by Felix TaschbachOur new paper is out in Science. We identified a subgroup of cholinergic neurons that mediate sensory modality-specific attention.
