We recently saw two people with lesions of the right mid to posterior insula.
What do you guess – they lost all desire to enjoy which of these guilty pleasures:
A. gambling
B. sex
C. eating junk food
D. getting massages

The localization for these two lined up perfectly with a recent large-scale lesion study from Nick Trapp’s lab @NickTrapp13 showing reduced appetite and weight loss associated with right insula lesions.

For a deeper dive into the insula structure and function here's a previously posted overview: x.com/boeslab/status/1771200…

Why is the insula the most interesting region in the brain?
Here are 6 things worth knowing. This is topic #3 for our lab's Friday 'Ode to Neuroanatomy' series.

Congrats Asmaa!
Nothing is more exciting than being among inspiring neurology leaders and talks.
So honored to be recognized at the AAN as a trainee scholarship recipient. @AANmember
Always grateful to you, @boeslab, for all the support you’ve given me as I take my early steps in research.

A new TMS protocol:
100-Hz intermittent theta burst TMS. Initial safety testing in press.
If we see triple the modulatory effects, as in rodents (Hanbing Lu) this will be a big step forward for TMS

Why 100-Hz iTBS? This is actually the stimulation pattern discovered in the 1980s that is optimized LTP\neuroplasticity.
50-Hz was only used because TMS machines were not capable of delivering 100-Hz in 2005.
50-Hz was a placeholder until TMS technology improved, and it has.

📢 Can noninvasive TMS reach & modulate the human hippocampus? 🧠⚡🧲 Multimodal evidence (TMS-iEEG TMS-fMRI) from our new @NatureComms paper says YES: shorturl.at/fqtYR
Here’s what we did and why it matters. 👇

I'm incredibly honored to share that I have been selected to receive one of the American Brain Foundation's Next Generation Research Grants, specifically the award in epilepsy!
Presenting 14 new Next Generation Research Grant recipients for 2026! These brilliant early-career researchers will study brain conditions from ALS to stroke. Their innovative work will make an important difference in the fight against brain disease.

The Third Brain Stimulation Subspecialty Summit (Mar 23-24, Boston) is open for registration!
By popular demand, this year we increased capacity to 400 attendees.
If you are involved in brain stimulation subspecialty training, you will want to be there.

Tsang et al. reviewed 13 studies combining TMS with intracranial EEG in humans and non-human primates. They found that stimulation can rapidly alter neuronal activity and connectivity, with some effects persisting for extended periods. tinyurl.com/yver3s93

A recent paper in @NatureNeuro 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" biorxiv.org/content/10.64898…

Agree! High spatial correlations of unthresholded network maps is pretty weak sauce. If statistical thresholds are used their only analysis falls apart.

Are connectome-based network mapping methods and the >200 papers that have used it invalid?
New paper out in @NatureNeuro says YES. nature.com/articles/s41593-0…
I have concerns about this new paper's methods and conclusions, but am biased. What do others think?

Is lesion network mapping fatally flawed?
New Nat. Neurosci article suggests high spatial correlation amongst lesion network maps invalidates the method.

My first impression is that the article raises an important point. Kudos to the authors for that. A critique is they don't really define how high of a spatial correlation is too high, just a sweeping generalization that it must all be garbage. Good debates ahead I imagine

‘Mapping the neuroanatomy of dystonia using causal brain lesions’ – now out as a preprint! medrxiv.org/content/10.64898… Huge thank you to @JJoutsa @foxmdphd!
We map the brain networks for the different types of dystonia, showing significant differences, somatotopy...and much more!!

Check out our poster on the role of lesion-derived networks in predicting post-stroke epilepsy in children @AmEpilepsySoc
Incredibly honored to receive the AES 2025 Young Investigator Award.
Grateful to my mentor @boeslab whose guidance and inspiration shape my work every day.

We'll have our Iowa Lesion Retreat tomorrow.
The topic this year:
'Neuropsychology of Personality'
We'll do a deep dive with lectures from luminaries on personality and how brain lesions influence personality and psychopathology.
