welcome to the
simultaneous electroencephalography (EEG) and magnetoencephalography (MEG)
recordings measure, directly on the scalp, the electric and magnetic components of the signal generated by populations of cortical neurons synchronously active, whereas localizing the generators of these scalp recordings along the cortical surface remains challenging and requires solving an ill-posed inverse problem
simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI)
recordings measure, within the whole brain, the hemodynamic responses that correlate with scalp EEG. EEG/fMRI is used to study the hemodynamic processes elicited by specific tasks, or at the time of spontaneous transient discharges detected on scalp EEG (e.g. epilepsy or sleep specific discharges).
simultaneous electroencephalography (EEG) and functional near infrared spectroscopy (fNIRS)
recordings measure local cortical fluctuations of oxy-hemoglobin (HbO) and deoxy-hemoglobin (HbR) that correlate with scalp EEG. As a wearable neuroimaging technique, fNIRS exploits absorption properties of infrared light within brain tissue using optic fibers placed on the head surface, to monitor brain hemodynamic processes during prolonged periods of time, including whole night monitoring.
our overall research project aims to perform a multimodal integration of functional imaging data to characterize physiological and pathological brain processes, for applications in sleep and epilepsy
