Artificial Intelligence (AI) Can Read Your Thoughts with Up to 80% Accuracy
After scanning the brains of volunteers, a research team from Osaka University (Japan) is able to understand thoughts and even record the dreams of those individuals.
The authors explain: “Our method can recreate high-resolution images from human brain activity.” They determined that the algorithm yields results with up to 80% accuracy compared to the original, similar to a previous study from Cornell University (USA).

The research published on bioRxiv utilized brain scans of four individuals who were shown images of stuffed bears, trains, clock towers, and people skiing.
The authors employed functional magnetic resonance imaging (fMRI), a brain scanning technique that measures slight changes in blood flow associated with brain activity. This technique can examine which parts of the brain are processing critical functions such as language and memory, as well as assess the impact of strokes or other diseases.
The scans identified the areas of the brain activated while participants viewed each image.
Subsequently, scientists used a stable diffusion model to recreate images corresponding to the thoughts of the participants. They conducted recognition tests based on the algorithm to determine whether the AI-generated images matched their corresponding original images or were merely random.
“Overall, the quality of reconstruction is stable and accurate. These results indicate that our method captures the content of thoughts at a high level,” the researchers affirmed.
According to The Sun, AI technology is increasingly contributing to the healthcare sector. Last year, the National Health Service (NHS) in the UK revealed that it would use AI to detect, screen, and treat individuals at risk of hepatitis C, aiming to eliminate this life-threatening disease by 2030.
Meanwhile, experts are concerned that ChatGPT could help students pass exams to qualify as doctors.
