Scientists Use Artificial Intelligence to See What the Brain is Thinking

JAKARTA, NNC - Scientists in Japan are using artificial intelligence (AI) technology to study electrical signals in the human brain. The study is aimed at determining what images are being viewed and thought about in the brain.
As quoted from Daily Mail, the findings were developed at the Kamitani Laboratory at Kyoto University, headed by Professor Yukiyasu Kamitani. They use artificial neural networks to create images based on information from fMRI (Functional Magnetic Resonance Imaging) scanning, which detects changes in blood flow to analyze electrical activity.
Theoretically, the technique can create recordings of memories, daydreams, and other inner or psychic images.
On the other hand and interestingly, this technology can help patients with persistent vegetative conditions (partially conscious condition but does not show perceptions and cognitive reactions to stimuli) to communicate with others.
The machine produces images that resemble stimulus images (both natural and artificial objects) and subjective visual content during imaging.
The artificial nervous tissues of the Kyoto team have been trained with 50 natural images and fMRI results from the volunteers staring at them. The tool then re-creates the image seen by the volunteers.
They then use the second type of AI called the Deep Generative Network, to check if the images look real, making them more recognizable.
