AI framework improves brain sulci labeling with geometric and semantic learning

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework called Geometric-to-Semantic Spherical Transfer Learning to address the challenge of labeling cortical sulci in brain scans. This method utilizes a large dataset from the UK Biobank to pre-train a spherical encoder, capturing complex topological features without expert annotations. The pre-trained model is then enhanced with semantic input from extracted sulcal lines using a Topological Prior Injector, improving performance on variable and rare sulci. AI

IMPACT This research could lead to more accurate and efficient analysis of brain structures, aiding in neurological studies and diagnostics.

    Geometric-to-Semantic Spherical Transfer Learning for Cortical Sulci Labeling

    arXiv:2609.12627v1 Announce Type: new Abstract: Deep learning on cortical surfaces faces a dilemma: capturing the complex topology of over 60 nomenclature-dependent sulci per hemisphere requires high-capacity models, yet the extreme scarcity of expert annotations ($N=62$ subjects…
