A recent @natneuro.nature.com paper analyzed lesion network mapping and raised concerns about the validity of the method. See below 👇 for our response. www.biorxiv.org/content/10.6...
A recent paper in @natureportfolio.nature.com raised concerns about the lesion network mapping method. Our team of 16 coauthors analyzed >1000 lesions and 34 symptoms and found that "The methodological foundations of lesion network mapping remain sound" www.biorxiv.org/content/10.6...

🧠 Deep brain stimulation for Parkinson’s disease achieves its best results when a precisely defined brain network operating in the high beta frequency range is targeted. This was shown by a team @andreashorn.org @bahnebahners.bsky.social in both space and time for the first time.👇 uni.koeln/5LYV7

Looking forward to reading this paper (see thread). 👀 #neuroskyence
The organization of function is mostly determined by anatomical connectivity, but that’s quite different from cytoarchitecture, which is how Brodmann areas are defined. Connectivity-defined areas probably don't have compact blobby shapes, and are definitely patchy.

My med school textbook says stimulants like Ritalin treat hyperactivity by “stimulating” the brain’s attention and cognitive control systems. We studied children taking stimulants in the ABCD Study, and the largest differences were actually in arousal and reward networks! Check out our preprint!
Tremor is a common symptom across many neurological disorders. But is there a shared tremor circuit across disorders - one that could guide treatment, regardless of diagnosis? We think: yes. Our study is out now in @natcomms.nature.com: 🔗 www.nature.com/articles/s41... 🧵 A thread.
