EEG-based neurofeedback and event-related potentials in autistic adolescents (empathy)

• Empathy and event-related potentials were measured before and after EEG-based neurofeedback training in autistic adolescents.¹
• ERP changes track neurofeedback effects, with relevance to EEG BCI and neurofeedback methods in clinical populations.^{1 1}

• The study (Scientific Reports, 2025) was a randomized, controlled pre-post-test clinical trial testing slow cortical potential (SCP) neurofeedback aimed at prefrontal regions to improve emotion regulation and empathy in children and adolescents with autism spectrum disorder.^{2 3}
• It enrolled 41 participants, with 21 assigned to SCP neurofeedback training and 20 to treatment as usual, and participants could continue stable usual care during the trial.^{2 3}
• Empathy was assessed with an adapted and extended Multifaceted Empathy Test (MET-J), alongside EEG recording of event-related potentials — specifically the N170, P300, and Late Positive Potential (LPP) components.^{2 3}
• The main finding was a significant group × time interaction in P300 latency, with shorter latencies in the neurofeedback group and longer latencies in controls, though post hoc comparisons did not reach significance.^{2 3}
• A trend toward reduced P300 peak amplitude in the experimental group after SCP training suggested possible modulation of attentional processing.^{2 3}
• Changes in the late LPP component were tied to reaction time for positive emotional stimuli: increased LPP amplitude corresponded to slower responses and decreased amplitude to faster responses.^{2 3}
• The authors frame SCP neurofeedback as potentially influencing cognitive efficiency and emotional processing in autistic individuals, while stressing that the effects are preliminary and post hoc tests were largely non-significant.^{2 3}
• They conclude further research is needed to confirm findings and optimize neurofeedback protocols, positioning this as EEG-BCI-relevant clinical neurofeedback methodology rather than an established treatment.^{2 3}
