Rationale: The monitoring of neurological pathologies, such as epilepsy, as well as neuroimaging protocols involving movement requires continuous and noninvasive brain imaging techniques. Among existing ones, functional near infrared spectroscopy (fNIRS) and electroencephalography (EEG) have the advantage of being inexpensive, may yield portable solutions and offer complementary monitoring of electrical and local metabolic/hemodynamic activities. Methods: We used a novel system with 128 fNIRS channels and 32 EEG electrodes to cover the entire adult superficial cortex, and monitor real-time electrical and hemodynamic activities in five epileptic patients. Results: Following instrumentation validation using visual and cognitive tasks on eight healthy subjects, long-term monitoring on four patients with epilepsy was done and data analysis confirmed expected hemodynamic variations during validation recordings and useful clinical information in the epilepsy monitoring unit. Conclusions: Preliminary results indicate that our multichannel and combined wireless fNIRS-EEG system can be used to detect simultaneous electrical and hemodynamic information in epileptic patients.
