Difficult decisions take time, but can we keep all accumulated evidence in mind long enough to make better choices? We find that working-memory limitations constrain decision-making, and these effects are modulated by dopamine. biorxiv.org/content/10.6... bioRxiv out with Cina Aghamohammadi et al.

Working memory limitations and dopamine modulation in probabilistic reasoning
Difficult decisions require gathering evidence over extended periods, placing demands on working memory. Yet, how working memory limitations affect decision-making remains largely unknown. We trained ...

Thank you for having me on BrainInspired, Paul @braininspired.bsky.social! It was such an honor to be on my favorite show—a rare place where we can leisurely talk about manifolds, latent circuits, power laws, and other esoteric ideas, and still be taken seriously in knowing they are all real.

Our work with @pawa-pawa.bsky.social is out in Nature Machine Intelligence! The choice of activation function affects the representations, dynamics, and circuit solutions that emerge in RNNs trained on cognitive tasks. Activation matters! www.nature.com/articles/s42...

Single-unit activations confer inductive biases for emergent circuit solutions to cognitive tasks - Nature Machine Intelligence
Recurrent neural networks are widely used to model brain dynamics. Tolmachev and Engel show that single-unit activation functions influence task solutions that emerge in trained networks, raising the ...

A study led by Cina Aghamohammadi is now out in ‪@natcomms.nature.com‬! We developed a mathematical framework for partitioning spiking variability, which revealed that spiking irregularity is nearly invariant for each neuron and decreases along the cortical hierarchy. www.nature.com/articles/s41...

Princeton’s @ilanawitten.bsky.social, @engeltatiana.bsky.social, and @jpillowtime.bsky.social have created the first-ever brain-wide activity map during decision making in mice as part of an international group effort known as the @intlbrainlab.bsky.social. 🔗 pni.princeton.edu/news/2025/fi...

New work with @shiyanliang.bsky.social‬, @roxana-zeraati.bsky.social, @intlbrainlab.bsky.social, Anna Levina. We uncover the principles that organize single-neuron timescales across the entire brain, unifying regional specialization with universal brain-wide dynamics: www.biorxiv.org/content/10.1...

Out today in @nature.com: we show that individual neurons have diverse tuning to a decision variable computed by the entire population, revealing a unifying geometric principle for the encoding of sensory and dynamic cognitive variables. www.nature.com/articles/s41...

“Like a group of skiers descending a mountain, each [neuron] prefers a slightly different path, but all are shaped by the same slope,” says PNI's @engeltatiana.bsky.social‬ on her lab’s new ‪@nature.com‬ study revealing how the brain makes decisions. 📰: pni.princeton.edu/news/2025/al...

Our new paper with @chrismlangdon is just out in @natureneuro.bsky.social! We show that high-dimensional RNNs use low-dimensional circuit mechanisms for cognitive tasks and identify a latent inhibitory mechanism for context-dependent decisions in PFC data. www.nature.com/articles/s41...
