- Reposted by Nosrat Mohammadi7 days of digital black-out in Iran. One week of darkness... Approximately 20,000 innocent, empty-handed protesters got killed!
- Over 12,000 people peacefully protesting against the current Iranian regime have been killed in just one week. These are among the darkest days of 2026. Shame on every country that recognizes the Iranian regime as a legitimate government that murders its own people.
- I came from Iran yesterday, by taking one of the last flights. The situation in Iran is unimaginable. There are unofficial reports that over 2000 protestors have been killed by the regime in the span of two nights, while the internet is cut off. The world must see this and must do something! #iran

- Reposted by Nosrat MohammadiVery excited about this new work from the omnipotent Owen, with me and Ashok Litwin-Kumar! Can we reconcile low- and high-dimensional activity in neural circuits by recognizing that these circuits ~multitask~? (Plausibly, yes 😊)
- 1/X Excited to present this preprint on multi-tasking, with @david-g-clark.bsky.social and Ashok Litwin-Kumar! Timely too, as “low-D manifold” has been trending again. (If you read thru the end, we escape Flatland and return to the glorious high-D world we deserve.) www.biorxiv.org/content/10.6...

- Modern way of thesis writing!
- Reposted by Nosrat MohammadiHow do we make sense of scientific literature that is growing explosively to the point where no-one could read all the relevant papers, and is contaminated with fraudulent and LLM-generated papers? I think that science isn't currently equipped to deal with this, and we need to. #science #metascience

- Reposted by Nosrat MohammadiHow does our brain excel at complex object recognition, yet get fooled by simple illusory contours? What unifying principle governs all Gestalt laws of perceptual organization? We may have an answer: integration of learned priors through feedback. New paper with @kenmiller.bsky.social! 🧵
- Reposted by Nosrat MohammadiExcited to share our new work with @engeltatiana.bsky.social! RNNs are often used to explore how the brain may solve specific tasks. We show that, depending on the architecture, RNNs find distinct circuit solutions, behaving differently when exposed to novel stimuli. www.nature.com/articles/s42...

- Reposted by Nosrat Mohammadiok, imagine you have an oscillation that is not symmetric around 0 (small direct current shift) with some amplitude modulation, for instance with 1/f-dynamics. ➡️ then these 1/f-dynamics will show up in low frequency part of spectrum (red); in addition to around oscillation peak (yellow).

We study how humans explore a 61-state environment with a stochastic region that mimics a “noisy-TV.” Results: Participants keep exploring the stochastic part even when it’s unhelpful, and novelty-seeking best explains this behavior. #cogsci #neuroskyence
