Reliability and signal comparison of OPM-MEG, fMRI & iEEG in a repeated movie viewing paradigm Optically pumped magnetometers (OPMs) offer a promising advancement in noninvasive neuroimaging via magnetoencephalography (MEG), but establishing their reliability and comparability to existing metho...

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. 🧠

Theoretical Neuroscience | Understanding Cognition | Xiao-Jing Wang | This textbook is an introduction to Systems and Theoretical/Computational Neuroscience, with a particular emphasis on cognition. It consists of three parts:

Fantastic textbook of theoretical and computational neuroscience by @xjwanglab, covering everything from biophysical circuits to cognition, full-brain models, neuro-AI and computational psychiatry. I can't recommend it enough for anyone in the field www.taylorfrancis.com/books/mono/1...

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?

Additionally, TMS to V1 also impacted alpha-lateralization for about 100ms after TMS pulse, thereby disrupting a well-established signature of WM.

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.

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.

Despite more than 3 dozen fMRI studies showing decoding of WM representations from early visual areas, the necessity of these areas for task performance has remained uncertain.

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
