New framework improves uncertainty calibration in M/EEG source imaging

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework for quantifying and calibrating uncertainty in Bayesian M/EEG source imaging. This framework compares two methods: Bayesian minimum norm (BMN) with sLORETA depth weighting, and sparse Bayesian learning (SBL) with sparse basis field expansions (S-FLEX). While both methods show residual miscalibration, SBL+S-FLEX demonstrates lower localization error and tighter uncertainties in simulations and real auditory MEG data. The study also explores adaptive noise learning and post-hoc isotonic recalibration to improve uncertainty estimates. AI

IMPACT This research could lead to more reliable and accurate analysis of brain activity data, potentially impacting fields that utilize M/EEG.

    Uncertainty calibration in Bayesian M/EEG source imaging

    arXiv:2611.06979v1 Announce Type: new Abstract: M/EEG source imaging requires accurate localization and reliable uncertainty estimates, yet posterior credible regions are rarely assessed for empirical calibration. We present a simulation-based framework for uncertainty quantifica…
