I've had a chat with Chris from #TheNakedScientists for the @elife.bsky.social podcast about our new paper "Predicting individual traits from models of brain dynamics accurately and reliably using the Fisher kernel": elifesciences.org/podcast/epis... #neuroskyence

Episode 97: February 2025
In this episode we hear about opioid overdoses, a new technique for studying teamwork in animals, making the most of fMRI data, how childhood adversity blunts the fear response in later life, and the ...

Read the short and sweet version of our new paper about predicting from brain dynamics, featured in elife digests magazine: elifesciences.org/digests/9512... #neuroskyence The intuition is that our approach uses a useful projection - like shining a light on an object and looking at its shadow

Predicting individual traits from dynamic brain activity
A combination of machine-learning techniques and more traditional modeling approaches can use the unique patterns of brain activity that evolve over time to predict traits such as age and cognitive ab...

Predicting individual traits from models of brain dynamics: In our new paper with Mark Woolrich & Diego Vidaurre in @elife.bsky.social, we combine a generative model of brain dynamics, here the Hidden Markov Model, with the Fisher kernel to predict individual traits elifesciences.org/articles/95125

Predicting individual traits from models of brain dynamics accurately and reliably using the Fisher kernel
The HMM-Fisher kernel approach leverages individual signatures of brain dynamics for prediction, which can be used, for example, to search for brain dynamics-informed biomarkers of neuropsychiatric di...
