- Reposted by diksha guptaExcited to see this Version Of Record of my work out in @elife.bsky.social! elifesciences.org/articles/106... We investigate the mental representation of geometric shapes in adults and children using fMRI and MEG. Each figure has a video of me explaining the figure: go and read it, or read below.
- come check out this #SfN25 minisymposium happening today at 2pm! we will discuss recent approaches to make sense of multi-area population dynamics www.jneurosci.org/content/45/4...
- @dikshagup.bsky.social will be presenting today in the minisymposium MIN23, between 2-4:30 pm in SDCC Rm 30 'A multi-region recurrent circuit for evidence accumulation in rats.' #SfN25
- Reposted by diksha guptaCome join us at #SfN25 for the minisymposium "Cognitive Maps in the Prefrontal Cortex"! Saturday, Nov 15, 2:00-4:30pm, Room SDCC 6CF www.abstractsonline.com/pp8/#!/21171... We will explore how the PFC represents structured relationships across species and how this supports flexible behavior.
- Reposted by diksha guptaIntroducing hMFC: A Bayesian hierarchical model of trial-to-trial fluctuations in decision criterion! Now out in @plos.org Comp Bio. led by Robin Vloeberghs with @anne-urai.bsky.social Scott Linderman Paper: desenderlab.com/wp-content/u... Thread ↓↓↓ #PsychSciSky #Neuroscience #Neuroskyence
- Reposted by diksha guptaI’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time! www.biorxiv.org/content/10.1...
- Reposted by diksha guptaHow does the brain decide? 🧠 Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc. After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up. rdcu.be/eGUrv
- Reposted by diksha guptaHappy to share the latest version of our work on compositional maps in hippocampus with Jo Warren, @jcrwhittington.bsky.social, @behrenstimb.bsky.social. We propose hippocampus constructs maps from cortical building blocks in replay – now with empirical support! www.nature.com/articles/s41... 1/9
- Reposted by diksha gupta1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

- Reposted by diksha guptaBAMB! is happening again in 2025. Learn how to model your behavioural data, next to the beach in Barcelona! keynotes this year from @athenaakrami.bsky.social and Peter Dayan.
- Our Barcelona-based summer school, BAMB! (bambschool.org) just opened applications! Come join us: 15-24th July, to learn how to model behavioral data using RL, Bayesian, latent variable models, RNNs, DDMs & more! #BAMB2025

- Reposted by diksha gupta1/ Super-excited to share our new work “Episodic and associative memory from spatial scaffolds in the hippocampus”, that just appeared in Nature! www.nature.com/articles/s41... Key insights and ideas 👇#tweeprint
- This is the future - fitting dynamical systems models with cell type specification 🔥🔥🔥
- Excited to share our NeurIPS spotlight paper that develops cell-type dynamical systems to understand the effects of neural perturbations, and roles of distinct cell classes in a neural circuit! Joint work w/ @dikshagup.bsky.social , Carlos Brody, @jpillowtime.bsky.social . (Details below)
