Lesion network mapping (LNM) links symptoms to brain circuits, but isolating symptom-specific effects remains challenging. We introduce robust LNM, a unified framework to reveal reliable, symptom-specific networks. biorxiv.org/content/10.64898/2026.05.18.725812v2

Association cortex connected to the striatum (esp. prefrontal) is more chained (catenated) than parietal regions belonging to the DMN (e.g. angular gyrus) and context-association network (CAN), with FC to the hippocampus. Why? what's the processing difference? www.biorxiv.org/content/10.6...

Much of subcortex had strong connectivity specifically to cortical chains. For example, a striatal seed produces connectivity to a single chain, not to a general cortical region. This was true across subcortical structures, suggesting that cortico-subcortical connectivity is organized by chain.
Function & cytoarchitecture don't overlap ... they're orthogonal. Prefrontal cortex is plastered with chains of functional patches previously mostly known from face processing. Why multi-modal parcellations are wrong ... and other insights hidden by group-averaging of fMRI data. great explainer👇🏻
I always assumed that brain function had to line up with cytoarchitectonics. It turns out I was wrong. Human cortex, especially PFC, is tiled by chains of functional patches that subdivide and interlink architectonic areas into parallel processing streams. www.biorxiv.org/content/10.6...

In case this important point gets overlooked: along with our Nature paper, we’ve publicly released two large and scarce datasets—PIPD and PIET. IMHO, these are the best open Parkinson's and Tremor datasets available to date. See threads (1/4) 👇 nature.com/articles/s41...

Good news for Parkinson's sufferers. These researchers should review recent papers on Essential Tremor. ET researchers have identified the back of the brain as the ET problem area, the same area identified as part of the Parkinson's problem. Potential for beneficial cooperation. (I have ET.)

Such a fascinating paper! Less than 3 years after the discovery of the new motor network (SCAN) interleaved between effector motor regions, SCAN is proving highly relevant for Parkinson’s! It offers potential to improve treatment and reduce symptoms non-invasively.

Washington University researchers scanned 863 patients and found that Parkinson’s is not just a motor disorder. It stems from hyperactivity in the brain’s somato-cognitive action network, and treatments work best when they calm this network. www.nature.com/articles/s41...

Immune cells from the gut drive development of Parkinson’s disease in the brain
In ‘body-first’ Parkinson’s disease, misfolded proteins propagate from the gut’s nervous system to the brain. Immune-cell activity seems to play a key part in this spread.
