👋🏼 I’m a biomedical engineer and currently a postdoc at Univ of Florida! I love all things deep brain stimulation 🧠⚡️ and identifying neuroimaging and neurophysiological markers to guide neuromodulation therapies for psychiatric and movement disorders. Happy to be here and connect with everybody!!
Preprint 🚨 Could ERNA be a potential biomarker to guide pallidal DBS for dystonia? We investigated in a small cohort (N=8 patients) and found ERNA predicted the therapeutic contact with ~90% accuracy, and ERNA frequency may be related to alpha power + cervical dystonia severity. Read more here:
Pallidal evoked resonant neural activity as a biomarker for deep brain stimulation in dystonia
Background Deep brain stimulation (DBS) targeted to the globus pallidus (GP) can effectively alleviate dystonia symptoms. However, identifying optimal therapeutic stimulation parameters is challenging...

Thanks for the highlight @andrewpines.bsky.social!!
Super cool talk by @karaannjohnson.bsky.social showing how evoked resonant neural activity (ERNA) can be used to guide DBS localization, direction, and (possibly even) more!

Thanks for the highlight @andrewpines.bsky.social!!
Thanks for the shoutout, Andy! Congrats on your amazing talk and award this morning as well 👏 #BrainStimConf
Great talk as always by @karaannjohnson.bsky.social complementing insights about ERNA in GPi DBS and dystonia.

I’m so thrilled to finally share the news of my NIH NINDS K99/R00 Pathway to Independence award!!! 🎉💃🏼 Long awaited and a little beam of light amidst the chaos and impending doom 😅 Words cannot express how much this opportunity to launch the next phase of my career means to me. A few notes below...

Is it critical to stimulate @ndosenbach.bsky.social's SCAN and CON networks for clinical improvements of Tourette's patients that undergo DBS?
Carlos Baldermann says yes in a cool new paper out in @natureportfolio.bsky.social comms today!
