Effect of Brain Computer Interface Training on Frontoparietal Network Function for Young People: A Functional...

Area of Science:

• Neuroscience
• Cognitive Science
• Rehabilitation Technology

Background:

• Inattention significantly impacts learning ability in young individuals.
• Frontoparietal networks (FPNs) are critical for attention and executive functions.
• Brain computer interface (BCI) applications in neurorehabilitation are established, but its cognitive effects require further investigation.

Purpose of the Study:

• To explore the impact of BCI training on the attention network in healthy young adults.
• To assess neuroplastic changes in FPNs following BCI intervention.
• To evaluate BCI as a potential rehabilitative approach for attention deficits.

Main Methods:

• Twenty-seven healthy adults underwent 5 days of consecutive BCI training.
• An Attention Network Test (ANT) was administered pre- and post-training.
• Functional near-infrared spectroscopy (fNIRS) was used for simultaneous brain activity recording.

Main Results:

• BCI training significantly improved BCI performance (p=0.005).
• Enhanced efficiency was observed in the alerting (p=0.032) and executive control (p=0.003) networks.
• Increased functional connectivity was noted in prefrontal cortices and the right posterior parietal cortex (p<0.05).

Conclusions:

• Repetitive BCI training can improve attention and induce neuroplasticity in FPNs.
• BCI shows promise as a rehabilitative strategy for individuals with attention deficits.
• The right posterior parietal cortex may serve as a key target for neuromodulation in attention-related disorders.
