This study will included 20 children presenting with epilepsy with spasms. It aims to offer these children, non invasively and without supplementary examinations, a recording of local and cerebral hemodynamic changes concomitant with an electroencephalographic recording during epileptic episodes. This will be carried out by combining optical imaging using near infra-red spectroscopy (NIRS) with electroencephalography (EEG), in a simultaneous high-resolution (HR) recording. This study is among those based on multimodal analyses of epilepsy, combining methods of analysis of electrical activity (electrical imaging) and hemodynamics (optical imaging). Surface electroencephalography (EEG) is a precious tool enabling the study of neuronal dysfunction from a functional point view. It is used in the routine follow-up of children with epilepsy. Optical imaging is a promising medical imaging technique. It uses light in the spectral regions of near infra-red as a source of radiation. It is quantitative, rapid, non invasive, and inoffensive which could easily be used at the child's bedside or in a clinical setting and can provide metabolic information about cerebral function. This study is multidisciplinary, which calls upon the skills of neurophysiologists, biophysicists, and clinicians
