Blown away after visiting INM-1 led by Katrin Amunts this Monday – Markus Axer and her showed us their setup of acquiring whole-brain slices (e.g. 7,000 of them to make up Bigbrain 1) – and the mesmerizing effects of polarized light on cryosectioned (raw) brain sections as can be seen in the video.

Super happy to have one of the official iconic BigBrain trophies on my desk after giving a keynote at the recent HIBALL summit.
Even though it was a nuisance and led to lots of issues in the BigBrain 1 space, this uniquely skewed brain shape is now iconic and went into the annals of neuroscience.

We made the tract openly available in our Lead-DBS software and its association with OCD symptom relief has been confirmed by a series of independent articles (for a review see: www.biologicalpsychiatryjournal.com/article/S000... ).

A 26-year-old female with refractory OCD who underwent bilateral ALIC DBS. Initial programming yielded limited benefit for OCD symptoms. Reprogramming based on the 'OCD response tract' led to additional symptom relief.

Of course most exciting for me: cytoarchitectonic proof that the VIM exists (and is not a subunit of VL as implied by the Jones nomenclature).

It is clear where I'm going: In the ACT-DBS framework we are proposing, AI-infused adaptive DBS will determine when to stimulate which symptom. Optimization-infused connectomic DBS will determine how to do just that.

This is a concept termed 'network blending' in a Prog Neurobiol. article by @barbarahollunder.bsky.social.

Using algorithms such as Cleartune (also introduced by Nanditha), we are already able to determine optimal stimulation settings for either symptom—or for any combination or blend of symptoms between them.

Enter connectomic DBS. @nanditharajamani.bsky.social showed us in her @natcomms.nature.com paper last year that stimulating two specific brain circuits will lead to maximal tremor vs. bradykinesia symptom improvements.

In #DeepBrainStimulation
the two major developments across the last decade have been
1. Adaptive DBS and
2. Connectomic DBS
In a @natrevneurol.nature.com article with @julianneumann.bsky.social, we ask:
Could the two be united into a common framework?
