Bust a move! Participants moved four body parts: hand, foot, face, tongue. We modelled each movement with a GLM and contrasted body parts: Face vs Feet, Face vs Hand, Hand vs Tongue, etc. The result - a textbook homunculus: face lateral, tongue ventral, feet dorsomedial, hand in between 🧠

Look at this beautiful figure of retinotopic mapping! Participants viewed a contrast-reversing checkerboard. We fit a pRF model per vertex on the cortical surface to estimate x, y, and pRF size. Each participant gets their own version of this, so you can define subject-specific visual ROIs! 👀

Everyone watched "Back to the Future" in the scanner, AND did somatotopic, retinotopic, and tonotopic mapping. As far as we know, it's the first public dataset combining all of this: full movie + 3 mapping tasks + eye-tracking + physio + behavioural tests in the same cohort

💥 Our paper on NNDb-3T+ is out in Scientific Data 🧵 A dataset that puts naturalistic movie-watching and controlled sensory mapping in the same 40 people, so you can link someone's individual brain topography to how they respond to a story 👇👇👇 www.nature.com/articles/s41...

Frontiers | Blurred magnitude homology of functional connectome for ASD diagnosis
Autism spectrum disorder (ASD) is one of the most common neurodevelopmental disorders. Existing studies show that adults with ASD may experience accelerated ...

👉 The key takeaway: these topology-based features seem to capture useful structure in directed brain networks and can complement more standard approaches for connectome-based classification

- Feed these fingerprints into a neural network to help distinguish ASD vs typically developing participants tested on a subset of 871 subjects (Autism Brain Imaging Dataset)

In this work, we: - Build directed brain networks from resting-state fMRI (using a simple time-lagged correlation) - Summarise each network with a set of topology-based fingerprints (called Betti curves) that capture global patterns like how the network connects and forms loops

Autism spectrum disorder is linked to differences in how brain regions communicate. Many fMRI studies build “brain connectivity maps” using correlations between regions, but those maps are usually treated as undirected, even though real brain interactions often have a direction

👉 What’s inside: • Full movie-watching inside the scanner (“Back to the Future” 🏎️💨) • Eye-tracking during movie-watching 👀 • Tasks to create individual maps of somatomotor, auditory and visual cortices (somatotopy, tonotopy, and retinotopy) 🧠 • Pulse oximetry 📈

🆕 New open neuroimaging dataset released! I’m happy to share that our Naturalistic Neuroimaging Database (NNDb3T+) is now publicly available! NNDb3T+ captures rich, multimodal brain activity in a naturalistic setting with 40 participants and over 160 hours of scanning!
