The 6x US memory champion – Nelson Dellis – can memorize a deck of cards in 40 seconds and knows the first 10K digits of pi. To figure out how, he let us peak inside his brain. Here is what we learned in our precision brain mapping study

This is your brain on Ritalin. Got your attention? Stimulant medications like Ritalin (methylphenidate) do, but not in the way you might think. They don't act directly on the brain’s attention systems! Find out what's really happening in

I've been thinking a lot about the preprint in terms of my own career. I grew up academically in computational labs. My papers were abstract early on and they only got more abstract as I progressed. The model was: find a new exciting mathematical tool. Apply it to brain imaging data. Write it up. 1/

When nothing worked, this did. Precision functional mapping is here for treatment-resistant depression. This is what hope looks like. 💡

At home, we used Bayes Tuning, an optimization procedure to refine and personalize stimulation settings. @ 7 weeks → suicidal thoughts gone. @ 6 Months → depression in full remission. @ 30 months later → Mike is still well. As a bonus some of if cognitive skills improved!!

Now with PFM, prior cortical stim work by
@ziad-nahas.bsky.social
for depression could be patient specific. We developed the end-to-end minimally invasive PACE used by
@drdaviddarrow.bsky.social
to place electrodes directly on Mike's salience, default, fronto-parietal, and action mode networks.

Using Precision Functional Mapping (PFM) we mapped Mike’s unique brain networks. We found his salience network was 4× larger than normal - it encroached on mood and attention systems.

what a privilege to have been a part of such meaningful work this early in my career! So excited for the future of personalized intervention! So inspired to continue the work standing on the shoulder of scientists who brought us here today! 🧠

Our proposed model: Pain is not a static signal. It’s a dynamic, modulated feedback loop for guiding behavior. Intervening at SCAN/AMN breaks the cycle — better than any one-size-fits-all cortical stimulation.

So, we examined it in our prior cortical stimulation patients. Two patients with central neuropathic pain. One had electrodes over both SCAN & AMN. One hit only SCAN. Pain relief tracked exactly with network engagement. Precision matters!!!!

Figure 1 (attached) shows how these networks: • Interdigitate with traditional motor areas • Align closely with pain activations (r=0.73) • Vary dramatically between individuals These are non-sensory pain networks. That’s why classic targeting misses.

Chronic pain affects 1 in 5 adults, yet current treatments — meds, DBS, SCS — often fail. Motor cortex stimulation sometimes works. 🤔 But why? We now have the answer: it’s not just the motor cortex. It’s how the brain integrates pain with action.

I'm thrilled to share that my graduate school project was just published in Nature Mental Health! We found that resting-state functional network predictors are more similar within vs between categories of internalizing and externalizing behavior in children (ABCD), adolescents (HBN) and adults (HCP)

hey -- i'm hiring a postdoc! the ad will be up shortly, but looking for someone with network neuroscience experience (very broadly). the position isn't tied to any specific project/grant, so lots of flexibility in terms of what you'd actually *do*. hmu if you might be interested/want to learn more!
