big thanks to all participants making this work possible with open sharing of their data, and shout out to all co-authors: @alexngo.bsky.social @ellasahlas.bsky.social @drchifa.bsky.social @leechbrain.bsky.social @themindwanders.bsky.social @borismontreal.bsky.social + non-bluesky-users

Very happy to see this last thesis paper in press @natcomms.nature.com! We combine intracranial EEG with multimodal MRI to study how interregional similarity in neurophysiology relates to different network scales ⚡ 🧠

Epilepsy imaging-genetics paper is fresh off the press!

Poster titled "Neuromod: The Courtois Project on Neuronal Modelling" with logos from Université de Montréal and the Centre de recherche de l'Institut universitaire de gériatrie de Montréal. Large bold text reads: 6 BRAINS – 987H-fMRI – 18 TASKS Followed by the subtitle: Naturalistic & Controlled – Multimodal / Perception + Action Each letter in "18 TASKS" contains thumbnails from various visual tasks. The central table summarizes 32 datasets grouped by primary domain (Vision, Audition, Language, Memory, Action, Other). For each dataset, the table indicates which stimulus modalities were used (Vision, Speech, Audio, Motion), what responses were collected (Physiology, Eye tracking, Explanations, Actions), and how many sessions and subjects were scanned. The overall visual style is playful and bold, with rainbow colors for modality types and rich iconography indicating data types.

In 2019, the CNeuroMod team and 6 participants began a massive data collection journey: twice-weekly MRI scans for most of 5 years. Data collection is now complete! 1/🧵

Brain Surfaces of 70 primate species

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

Genetic foundations of interindividual neurophysiological variability Individual brain activity profiles are shaped by lifelong genetic influences.

Very proud to share this one🥹! We show that personalized signatures of brain activity are heritable and relate to the expression of specific genes. That means my brain-fingerprint is very similar to my twin brother's! #ResearchIsMeSearch🧠 🧬 ♊️

How does the human brain coordinate hierarchical cortical development? Our work in Nature Neuroscience identifies a role for thalamocortical structural connectivity in the expression of hierarchical periods of cortical plasticity & environmental receptivity in youth 🧵 www.nature.com/articles/s41...

New year, new preprint (+ last thesis paper!)

Macroscale gradients of intracranial EEG power spectra follow familiar axes: sensory-motor and unimodal-transmodal 🕵️‍♀️
Gradients show overall stronger association to distance, but multimodal information was best in transmodal areas 🧠

"exhaust fumes" made it into the official abstract!

hence completing the journey from an epiphenomenal shitpost blog to a full-blown review paper.

all thanks to this cast of co-authors (esp. Sander), our TICS editor Lindsey Drayton, and two very engaged reviewers (@danielemarinazzo.bsky.social)

Coming to #AES2024? Why spend the last conference day sleeping in when you could come to the Neuroimaging SIG? See you at 7am Dec 10 if you're curious about applications of brain gradients in TLE to understand cognitive and clinical phenotypes! 🌈 🌅

Just in time for #AES2024, let's grow this list of epilepsy imagers! go.bsky.app/HnaoTqF

Very happy to see this one out in the world 😁 a joint endeavour with Val Kebets 🌟

We used PLS to identify components linking symptoms of psychopathology with multimodal imaging markers in the ABCD dataset
