New framework BrainATCL learns adaptive temporal brain connectivity from fMRI data

By PulseAugur Editorial · [1 sources] ·

Researchers have developed BrainATCL, a novel unsupervised framework designed to learn adaptive temporal brain connectivity from functional magnetic resonance imaging (fMRI) data. This method addresses the limitations of traditional graph neural networks in capturing long-range temporal dependencies in dynamic fMRI signals. BrainATCL dynamically adjusts its lookback window and utilizes a GINE-Mamba2 backbone to encode spatial-temporal representations, incorporating brain structure and function-informed attributes for improved biological relevance. The framework has demonstrated superior performance in functional link prediction and age estimation tasks, including cross-session prediction scenarios, using data from 1,000 participants in the Human Connectome Project.

    BrainATCL: Adaptive Temporal Brain Connectivity Learning for Functional Link Prediction and Age Estimation

    arXiv:2508.07106v2 Announce Type: replace Abstract: Functional Magnetic Resonance Imaging (fMRI) is an imaging technique widely used to study human brain activity. fMRI signals in areas across the brain transiently synchronise and desynchronise their activity in a highly structur…
