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).

This study will involve 1) answering some questions about yourself and how you visualise images, and 2) watching videos of objects that are moved by different means and making simple judgements about them.

Happy 40th Birthday #TMS 🥳🧲🎈

Published in the Lancet on 11th May 1985, a 1-page report of a new device & the 1st TMS-evoked MEP changed brain stimulation research & treatment forever

We celebrated with Professor Barker two weeks ago in Birmingham

Here's to 40 more years!

So the individual p-values don't tell us how big either of those effects are or how different they are from each other so you can’t derive the interaction p-value from them.

I don't think so, because the tiny p-value shows the observed change is very unlikely under the null hypothesis (not that the effect is large), and a larger p-value can mean that there is high variability or low power, not necessarily that there was no change.
