Presenting our preprint work at the virtual @wmsymposium.bsky.social (WMS 2026). 📅 Tuesday, July 14th | 9:30 AM CDT 🗣️ Session A1: Control 1 There's a fantastic group of presenters lined up with tons of cool talks on working memory, representations, and attention. Link in the comments below!

New preprint! 🚨 Work w/ Sangita Dandekar & Clayton Curtis at NYU during my PhD. We show how prefrontal & visual cortices coordinate to keep working memories alive via localized & long-range β-band dynamics. 🧠 www.biorxiv.org/content/10.6... (1/5)

I am recruiting a postdoctoral researcher and a PhD student, funded by a new ERC grant. The grant focuses on the role of the hippocampus in visual perception, using 7T fMRI (hippocampal subfields, cortical layers) and MEG+iEEG. The intended start dates for both positions are in early 2027. 🧠🟦 1/3

What about top-down control? We found that prefrontal and visual areas exhibited discrete, transient windows of cross-hemispheric β-band synchronization during the delay. This points to a subtle, dynamically gated communication channel connecting the network. 🌐 (4/5)

In short: working memory isn't just passive storage in sensory cortex or an isolated executive function in PFC. It’s adynamic, distributed coordination of the two. PFC likely acts as a controller, using β-band sync to pattern sensory populations into stable memories. 🎬 (5/5)

Interestingly, β-band topography varied continuously based on stimulus location. This spatial patterning tracked the specific contents of memory and predicted trial-by-trial behavior—critically, in visual cortex, but not in prefrontal sources. 🎯 (3/5)

I’m off to #SfN2025! Grateful for the TPDA sponsor from @sfn.org. I will present in two sessions, details below. I’m seeking 2026 postdoc positions to continue research in animal cognition/naturalistic behaviors—if you’re looking for a neuroethologist and a mouse whisperer, come to see me!

How reliable is OPM-MEG, and how does it compare to other neuroimaging modalities? 🤔 In a new preprint with ‪@s-michelmann.bsky.social‬, we evaluate the reliability of OPM-MEG within & between individuals, and compare it to fMRI & iEEG during repeated movie viewing. 🧠 📄 doi.org/10.1101/2025...

Need more studies like these that combine decoding with perturbation to investigate the necessity of the "signature" for task performance.

This changes the question of whether V1 is "necessary" for WM to how does V1 retain information during WM without getting disrupted by a continuous barrage of visual inputs and maintain it within network of neurons having short time-constants?

Mrugank Dake
@thememoryguy.bsky.social

Here, using fMRI-guided TMS coupled with a unique design using subjective reports of phosphenes to present spatial stimuli, we perturbed V1 in a retinotopic manner while participants retained a spatial location in their memory.

Mrugank Dake
@thememoryguy.bsky.social

We found that TMS to V1 impacted WM performance not just during encoding as has been shown earlier in many studies, but also during maintenance. We also replicated the results in a followup-study.

Thanks for amazing supervision from Clayton Curtis and all the cool people from Clayspace lab and help from everyone at NYU CBI without whom this work would not have been successful. PS: it took over a year to get the TMS-EEG setup working!

Love this quote from Sir Michael Atiyah: "Algebra is the offer made by the devil to a mathematician. The devil says, 'I will give you this powerful machine...all you need to do is give up your soul: give up geometry...' when you do algebra...you stop thinking about meaning, about geometry
