EEG-metoder brukes for å trekke ut biomarkører av hjernedysfunksjoner. Fokuset er på flerkanals hendelsesrelaterte potensialer (ERPer) som er registrert i en cued GO/NOGO-oppgave. Ikke-hjerneartefakter korrigeres og ERPer sammenlignes med de normative dataene. Eksempler gjelder biomarkører for ADHD-diagnose og prediksjon av medisineringsrespons.
