Ballistocardiogram suppression in concurrent EEG-MRI by dynamic modeling of heartbeats. [PDF]
Hum Brain Mapp, 2022 The ballistocardiogram (BCG), defined as the induced electric potentials by the head motion originating from heartbeats, is a prominent source of noise in electroencephalography (EEG) data during magnetic resonance imaging (MRI). Here, a method called “dynamic modeling of heartbeats” (DMH) is proposed to reduce BCG artifacts in EEG data recorded inside

Estimation of fMRI responses related to epileptic discharges using Bayesian hierarchical modeling
Human Brain Mapping, Volume 44, Issue 17, Page 5982-6000, 1 December, 2023., 2023 A hierarchical model involving the local and distributed hemodynamic response homogeneity to regularize estimations of functional magnetic resonance imaging (fMRI) responses related to interictal epileptic discharges (IEDs). This model provides more physiologically reasonable and more accurate estimations of the fMRI response induced by IEDs compared ...
