Here’s how I’ve been utilising the excessive amounts of coffee I’m consuming at @westernu.bsky.social lately.

To find out about how #TMS #BrainStim users collect, analyse & share their data, we've made a very brief TMS survey:

It should take you less than 5 minutes & does not ask for any personal information.

We'll use the answers to plan our future work.

Please share!

🙏🙏🙏

New Open dataset alert:
🧠 Introducing "Spacetop" – a massive multimodal fMRI dataset that bridges naturalistic and experimental neuroscience!

N = 101 x 6 hours each = 606 functional iso-hours combining movies, pain, faces, theory-of-mind and other cognitive tasks!

With RESTORE, we aim to combine TMS & EEG to study the neural underpinnings of working memory. We plan to advance the use of TMS & EEG aiming to provide innovative approaches to the study of cognition. For a sneak peek, check out our recent perspective: www.frontiersin.org/journals/hum...

Today, I had my final walk around campus, remembering the very first visit. I joined Western in hopes of becoming a better scientist, and on top of that, I like to think that I became a better person.

But most importantly I was privileged enough to meet and collaborate with lots of amazing folks, for whom there are not enough words in this world to thank. Every single one of them taught me something that I will cherish for life.

Over the past couple of years I was lucky enough to call @westernu.ca my academic home.

During my time here I:
☕️ Drunk 849L of coffee.
💩 Stepped on geese poop 56 times.
🧻 Consumed ~1.5km of institutional toilet paper.
🪒 Grew 37 gray hairs.
⚡️ Delivered hundreds of thousands of TMS pulses.

New paper day! Whereas earlier studies have shown that human eye movement patterns are influenced by the physical properties of remembered stimuli, we show that they are also influenced by stimulus meaning. h/t to Ali Pexsa (not on bluesky) who led this work.

Human eye movements track stimulus meaning
Working memory (WM) is a capacity- and duration-limited system that enables the representation and processing of fleeting sensory phenomena. Human fMRI studies indicate that brain areas associated wit...

Introducing a new proxy of cortical excitability paves the way for wider use of TMS. Objective measures can be taken outside of M1, and TMS applications can now include individuals who are MEP-negative. [7/end]
phivph.com
Our sham controls show that pupil responses are not due to auditory artefacts. Additional alternatives were also ruled out. No pupil lateralisation effects were found (i.e., no spill-over iris muscle TMS), and no pupil size differences were found between high vs low MEP activity per intensity. [6/n]
phivph.com
Further, following inhibitory tDCS, we found a decrease in the TMS-induced pupil dilation peaks as compared to baseline, reflecting the anticipated cortical excitability decrease. [5/n]
phivph.com
These TMS-induced dilations were dissociable across TMS intensities and between sham & active TMS. [4/n]
phivph.com
In three experiments (total n = 59) we found consistent TMS-induced pupil dilations, that peaked approx. 1 s after TMS.

We showed this consistent effect in two different isoluminant conditions (300 & 400 lux) and with two different eye-trackers (eyelink & tobii). [3/n]
phivph.com
Speculations about the nexus between pupil size and cortical excitability have existed for a while, but evidence for this link is scarce and mainly indirect. We wanted to test it out, by measuring TMS-induced pupil dilations at different TMS intensities and before vs after tDCS inhibition. [2/n]
phivph.com
New preprint out, where we show that TMS-induced pupil dilations can be used as a measurable proxy of cortical excitability.

For TMS studies to be reproducible and for us to build on each other’s findings, we need to report what we actually did during the experiment.

We've built and now are evaluating the TMS-RAT (Reporting Assessment Tool).

Check out our website! - built by @thehandlab.bsky.social
tmsmultilab.bsky.social
The TMS-RAT v1.0 is now being tested!

It's a checklist / guidance tool to help researchers report #TMS studies & to facilitate quantitative comparisons in #systematicreviews & #meta-analyses

All the data will be made freely available; an interactive website will be coming. Stay tuned!

It’s not my fault. Semi-formal could also mean half the people come in formal wear, and the rest are casual 🤷🏼‍♂️
