AI can turn brain scans into sentences
Researchers in Japan have built an AI system that can read brain scans and turn them into full sentences, like "A person jumps over a deep waterfall on a mountain ridge."
This is all thanks to Dr. Tomoyasu Horikawa's team, who used fMRI scans to map out how our brains process what we see.
How the AI system works
The AI looks at brain signals, decodes their meaning, and then uses language tech to write out what you're thinking about or remembering.
It got things right about half the time for images people saw, and 40% of the time for memories—not perfect, but way better than guessing.
Implications for communication and mental privacy
This could be huge for people who can't speak due to conditions like paralysis or aphasia—their thoughts might one day be turned into text.
The team says they're not reading private thoughts but decoding general ideas from across the brain.
Still, as this tech grows, protecting mental privacy will be super important.
