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 ...

I am proud of this paper. Since it came out in 2022 it has received 0 citations (yes that's a zero). But multiple young scientists have found it useful! (from other labs, so they were not coerced...). Perhaps you will find it useful too? SOME TIPS FOR WRITING SCIENCE doi.org/10.1523/ENEU...

Some Tips for Writing Science

When preparing a scientific paper, we typically write with coauthors who have different backgrounds and styles, and we target readers who have little time and patience. To help both readers and writer...

Out today! Our (w/ @annaschapiro.bsky.social) review of the alignment between the C-HORSE model and the hippocampal structure learning literature. We find strong congruence with the model's key principles and propose several avenues for future investigation!

Evidence for complementary learning systems within the hippocampus

Abstract. Decades of research have established the hippocampus as central to episodic memory, but growing evidence suggests that it also contributes to str

New preprint: "Linear equivalence of nonlinear recurrent neural networks." For large nonlinear (potentially chaotic) RNNs with random connectivity, the full N×N covariance matrix takes the same form as that of a ~linear~ network with the same couplings, driven by independent noise.

Linear equivalence of nonlinear recurrent neural networks

Large nonlinear recurrent neural networks with random couplings generate high-dimensional, potentially chaotic activity whose structure is of interest in neuroscience, machine learning, ecology, and o...

New #NeuroAI #compneurosky preprint! To better understand how target-directed learning works in the brain, we sought to engineer an artificial neural network capable of solving complex image classification tasks that comprises only experimentally-supported biological building blocks. (1/15)

At the Bernstein Conference 2024, Jeremie Lefebvre and I organized a workshop on the computational consequences of neural heterogeneity. Now, slightly more than a year later, we funneled the emerging discussions into a perspective piece: www.cell.com/neuron/fullt...

How heterogeneity shapes dynamics and computation in the brain

No two neurons are the same, yet models often treat neural populations as pools of identical and interchangeable elements. Here, Dahmen et al. highlight recent theoretical advances that reveal the imp...

Thrilled that my paper is out in the @nature.com. We explored how the brain builds complex tasks by compositionally combining simpler sub-task representations. The brain flexibly performs multiple tasks by dynamically reusing neural subspaces for sensory inputs and motor actions rdcu.be/eRVUk
