arXiv:2604.24942v2 Announce Type: replace Abstract: Encoding models provide a powerful framework for linking continuous stimulus features to neural activity; however, traditional voxelwise approaches are limited by measurement noise, inter-subject variability, and redundancy arising from spatially correlated voxels encoding overlapping neural signals. Here, we propose an independent component (IC)-based encoding framework that dissociates stimulus-driven and noise-driven signals in fMRI data. We decompose continuous fMRI data from naturalistic story listening into ICs using one subset of the d
The increasing sophistication of AI models for language processing and the availability of large fMRI datasets are creating new opportunities for more nuanced brain activity analysis.
This research provides a more robust method for linking continuous stimulus features to brain activity, particularly during complex tasks like story comprehension, by mitigating noise and inter-subject variability.
Traditional voxelwise approaches are being surpassed by independent component-based encoding frameworks, offering clearer insights into how the brain processes information.
