- Reposted by Subham DeyLove this. “Spontaneous” has always really meant “we don’t know why X is happening”, a perspective tied to the dominance of structured task paradigms for studying cognition, behavior, and brain activity.
- Reposted by Subham DeyThe supplementary videos for this preprint are fantastic. Some wild examples of decoding the animal's attentional focus and/or intent www.biorxiv.org/content/10.6...
- The hippocampal map has its own attentional control signal! Our new study reveals that theta #sweeps can be instantly biased towards behaviourally relevant locations. See 📹 in post 4/6 and preprint here 👉 www.biorxiv.org/content/10.6... 🧵(1/6)
- Reposted by Subham DeyPreprint alert!!! We recorded directly from the human ventral tegmental area (VTA), the principal source of cortical dopaminergic innervation, while patients performed an instrumental learning task. 🧵👇 www.biorxiv.org/content/10.6...
- Reposted by Subham DeyMore than 200 published studies and at least seven ongoing clinical trials rely on potentially faulty brain network maps, according to a study published yesterday. By @avaskham.bsky.social #neuroskyence www.thetransmitter.org/brain-imagin...
- Reposted by Subham DeyWhere does learning through imitation happen in the brain? In juvenile zebra finches, we pinpoint a synaptic locus of song learning in a cortico-basal ganglia circuit and leverage this localization to measure the timescale of consolidation and make birds learn faster! #neuroskyence (1/14)
- Everyone knows the limitations of PCA, the distortions which it creates when doing dimensionality reduction. Yet people want to use it.

- Reposted by Subham DeyWhy does life explore so few of the forms it could possibly take? Using fractal descriptors, this #scienceadvances paper shows that Earth’s biosphere clusters around simple shapes, reflecting deep evolutionary constraints. @artemyte.bsky.social @manlius.bsky.social www.science.org/doi/pdf/10.1...
- Reposted by Subham Dey⚠️ New paper alert and what a way to end 2025! 🎉 Happy to share our story “Sleep-dependent infraslow rhythms are evolutionarily conserved across reptiles and mammals.” published today in Nature Neuroscience. Sleeping dragons 🦎 and functional ultrasound! Read the full paper here: rdcu.be/eWJHb 1/8

- Reposted by Subham Dey1/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...

- There is a reason why variants of Kalman filter like Unscented Kalman Filter, Cubature Quadrature Kalman Filter exists in literature. Still you find the Kalman filter at big ticket neuroscience journal papers. It seems neither the people nor the reviewers care at all.
- Reposted by Subham DeyOut today at Neuron, our experiments show that frontal cortical representation of economic variables is jointly determined by spatial organization and downstream connectivity of neurons, revealing a structured, multi-scale code for economic variables. www.cell.com/neuron/fullt...
- Reposted by Subham DeyThrilled to share that our work is now published in Science! ✨ We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭 www.science.org/doi/10.1126/... 🧵1/

- Reposted by Subham Dey🚨We believe this is a major step forward in how we study hippocampus function in healthy humans. Using novel behavioral tasks, fMRI, RL & RNN modeling, and transcranial ultrasound stimulation (TUS), we demonstrate the causal role of hippocampus in relational structure learning.

- Reposted by Subham DeyMy first paper with @naoshigeuchida.bsky.social is finally out in @natcomms.nature.com ! rdcu.be/eACGf TL;DR: asymmetric learning rates can be induced by shifts in tonic dopamine giving rise to pessimistic/optimistic biases in agents or animals undergoing reinforcement learning .
- Reposted by Subham Dey🚨Very happy that my PhD work is now out in @nature.com! We discovered that evolution, by acting in the midbrain, shifted the threshold to escape in Peromyscus mice, to fine-tune defensive strategies in different environments www.nature.com/articles/s41... This was a truly collaborative effort! 🧵⬇️
- With adaptive deep brain stimulation getting FDA approved, we should see more closed loop control algorithms rather than proportional integral or on/off switching controllers. One method is called direct data driven model predictive control.

- You have a nonlinear generative model for recorded neural data, then you again linearize it using koopman operators to design linear optimal control input. There are already ample works in the literature where you can design nonlinear energy efficient optimal controllers for nonlinear systems.
- Writing papers in LaTeX (Overleaf) is a basic undergraduate skill set which one should acquire. (in my opinion)

- z-transform and z-score are two completely different entities. Using one in place of the other is not correct in my opinion.
