Résumé / Abstract

BIOFEEDBACK-SUPPORTED self-regulation of slow cortical potentials (SCP) is increasingly being used for treatment of intractable epilepsy. However, it is unknown whether the acquired ability to regulate one's own cortical potentials remains stable over time. In this study, 18 patients with drug-resistant partial epilepsy performed 35 training sessions in which they learned to generate slow cortical potential shifts in either positive or negative direction. At the end of training, they differentiated significantly between required cortical positivity and required cortical negativity. Six months after this point, they still demonstrated an unchanged between-condition differentiation. The performance in the booster session was particularly good in trials without continuous SCP feedback. The ability to generate positive SCP shifts was related to decrease of seizure frequency during the 6 months follow-up period compared with the 3 month baseline period. This data indicate that the acquired ability of humans to regulate their cortical potentials did not decrease over a 6 month period but rather, tended to consolidate.
