The Efficiency of a Multimodal Neurotechnological Intervention (Cerebral Photobiomodulation, qEEG Neurofeedback, andHeart- Brain Biofeedback) in Enhancing Attentionand Academic Performance in Middle SchoolStudents (11-15 years old): A NationallyCondu

The purpose of this nationally conducted randomized controlled clinical study is to evaluate the efficiency of a multimodal neurotechnological intervention (gamma cerebral photobiomodulation at 40 Hz, personalized EEG neurofeedback, and heart–brain biofeedback) in enhancing attention and academic performance among urban middle-school children aged 11 to 15 years. The study involves a total sample of 200 healthy participants, equally distributed into an experimental group (n = 100, 50 girls and 50 boys) and a control group (n = 100, 50 girls and 50 boys). The intervention spans one year and is structured into three therapeutic cycles, each lasting 10 weeks with two weekly sessions, followed by 10 weeks of break between cycles. The primary evaluations exclusively involve objective measurements of brain activity through quantitative electroencephalography (qEEG Brain Mapping), with a focus on specifically selected Brodmann areas, chosen for their demonstrated roles in regulating attention and cognitive performance (BA 5, 8, 19, 21, 22, 39, 44). Secondary evaluation involves objectively assessing physiological stress through heart coherence measurement (heart–brain biofeedback). Statistical analyses include paired and independent samples t-tests, repeated- measures ANOVA, and effect size calculations (Cohen’s d). The anticipated outcomes of the study are significant and objective increases in qEEG parameters within the selected cortical areas, correlated with evident improvements in attention, concentration, and academic performance. This study aims to validate and demonstrate the efficacy of an integrated neurotechnological approach as a proactive and preventive method for optimizing cognitive and academic performance during the critical cognitive developmental period of middle school. Practical implications of these findings support the integration of this type of intervention into educational and preventive clinical programs aimed at improving attention and academic achievement on a national scale.
