In this regard, we would like to survey the electrophysiology community on its present needs and to address them in a data-driven manner. We invite researchers in the community to take 5 minutes of their time to answer this poll: <a href="https://forms.gle/k8qpW1ddyk4Hqh5q8" class="">https://forms.gle/k8qpW1ddyk4Hqh5q8</a>. Your feedback and suggestions are very important to us.<br class=""></div><div class=""><br class=""></div><div class="">Best,<br class="">BIDS derivative team for electrophysiology</div></body></html>
