Eager to share isoCycle! If interested in neural dynamics across timescales, it might be worth exploring

در این‌که از زنده بودن، شرمگینم، هنگامی که این‌همه جوان زندگی‌ناکرده پرپر شده‌اند، هیچ گزافه و اغراقی نیست.
هزار هزار بیژن و بهرام و گستهم بر خاک دیدم که در پی‌ نور می‌گشتند و تاریکی، چشم و جان‌شان را گرفت. یک نسل درخشانِ ایران‌خواه را بی‌سر و ایران را بی‌آینده کردند ...

[Reza Pahlavi @PahlaviReza]

My OpEd in the @WashingtonPost setting out my plan to bring an end to the criminal regime in Iran, our roadmap to a prosperous and democratic future, and my vision for my country. I have stepped forward to lead this transition to freedom.

If you are around at #NeurIPS2025, come check out this amazing workshop where I am presenting:

Interpretability at the Network Level: Prior-Guided Drift Diffusion for Neural Circuit Analysis

Models at early epochs know much more than we thought!

I will be presenting part of this work in workshop on
Interpreting Cognition in Deep Learning Models @CogInterp @NeurIPSConf Dec 7th, Room 5AB

Unifying Gestalt Principles Through Inference-Time Prior Integration
#NeurIPS2025
Also, some cool papers here!

[Tahereh Toosi @taherehtoosi]

How 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 Ken Miller! 🧵

[Cina Aghamohammadi @CAghamohammadi]

Thrilled to share our @NatureComms paper on Doubly Stochastic Renewal (DSR) for partitioning spiking variability (w/ Chandramouli Chandrasekaran & @EngelTatiana). DSR provides a robust mathematical foundation for modeling latent dynamics.

[Amirhossein Farzmahdi @farzmahdi]

Excited that our work is out together with the amazing @CoenCagli_Lab and Adam Kohn! We demonstrate how neural co-variability in the visual cortex encodes uncertainty about natural scenes and is adaptively modulated by spatial context! (1/7)

@PessoaBrain we have tried to isolate some ultra slow cycles in population spiking, pupil and facial motion https://t.co/vTQ7VZbGsT

[Ehsan Sabri @FourierBrain]

There are also ultra-slow rhythms that are usually cut off in LFP and EEG by the amplifier but can be accessed by examining network spiking rate changes. These slow cycles seem to be also the basis functions underlying the fluctuations in pupil size and mice facial motion!
