Three interventions will be administered:

• An electroencephalography recording (EEG) for 30 minutes.We will use an electrocap of 19 scalp locations according to the International 10-20 EEG placement system.
• The second intervention is the neuropsychological assessments and questionnaires. They will be done in one session for approximately 2 hours.
• The third intervention is the neurofeedback training sensorimotor/delta ratio that will be recorded at channel Cz according to the International 10-20 system.

• The psychopedagogical care : Each session will be organized using the same video material than for the NF training sessions.

Neurofeedback experiment will consist of 30 sessions of neurofeedback training, twice or three times a week during maximum 4 months. The two experimental groups will undergo questionnaires, EEG recording and neuropsychological assessments in three-time points, pre-training (T0), post-training (T1) and 3 months follow-up (T2). Electroencephalography will be recorded by a technician in EEGFor each participant, EEG power spectrum will be calculated in pre (T0) and post neurofeedback training/psycho-pedagogical care at T2 and T3.
