AI-Powered Brain Stimulation System Enhances Concentration at Home

Innovative AI-Driven Brain Stimulation System

Researchers from the University of Surrey, the University of Oxford, and Cognitive Neurotechnology have developed a groundbreaking personalized brain stimulation system powered by artificial intelligence (AI) that can safely enhance concentration from the comfort of one's home 1

. This innovative technology, designed to adapt to individual characteristics, has the potential to help people improve focus during study, work, or other mentally demanding tasks.

How the System Works

The system utilizes transcranial random noise stimulation (tRNS), a gentle and painless form of electrical brain stimulation, alongside an adaptive AI algorithm 2

. This AI learns to personalize stimulation based on individual features, including attention level and head size. By tailoring stimulation intensity to these characteristics, the system can identify optimal settings without the need for expensive MRI scans, making the personalization both scalable and cost-effective 1

Research and Development Process

The AI was trained using data from 103 people aged 18 to 35, who completed 290 home-based sessions using CE-marked (European Union standard) headgear and a tablet-based sustained attention task 3

. Following this training phase, the system was evaluated in a double-blind study involving 37 new participants.

Significant Results and Improvements

The study, published in npj Digital Medicine, revealed that participants who received personalized AI-guided stimulation showed significantly better performance than during standard or placebo stimulation 1

. Notably, the strongest improvements were observed in individuals who initially demonstrated lower levels of attention 2

2

. This finding suggests that the system could be particularly beneficial for those struggling with focus and concentration.

Safety and Efficacy

Professor Roi Cohen Kadosh, Head of Psychology at the University of Surrey and lead author of the study, emphasized the safety and effectiveness of the system 3
