Revealing the Spatial Pattern of Brain Hemodynamic Sensitivity to Healthy Aging through Sparse Dynamic Causal Model
Age-related changes in the BOLD response could reflect neurovascular coupling
modifications rather than simply impairments in neural functioning. In this study, we propose …

Sparse and Data-Driven Methods for Concurrent EEG–fMRI
Independently, EEG and fMRI offer either particularly rich temporal (EEG) or spatial (fMRI)
information related to the neural dynamics in the brain. In theory, the two modalities could be …
