Familiar brain waves have long been used in clinical medicine, such as checking for problems such as epilepsy and sleep disorders. Japan's "Yomiuri Shimbun" recently published an article stating that combining brain wave monitoring with the latest information technology and artificial intelligence can help "decipher" people's psychological states and intentions.

A company called "ARAYA" in Tokyo, Japan, has developed such a system: the tester's head is connected to an electronic device, facing the computer screen, and the text in the computer has multiple colors. The tester just repeated "green, green" silently in his mind, and the green copy was sent out by email.

Shuntaro Sasai, head of the company's research and development department, said it was the test subject's brain waves that gave the instructions. According to reports, although there are still difficulties in accuracy, artificial intelligence can analyze brain wave data to determine which color a man has chosen. It is hoped that "telepathy technology that can communicate without speaking" can be developed in the future.

Brain waves are wave-like electrical signals emitted when the brain is active. Previously, due to limitations such as skull coverage, the brainwave information that people could capture was limited. In recent years, through the effective use of artificial intelligence that can read large amounts of data, it has become possible to analyze detected brain wave data in a short time. Mingyuan Chong, an expert in brainwave research and professor of systems neuroscience at Tohoku University in Japan, explained that advances in information processing and analysis technology have made it possible to find various information hidden in brainwaves.

Researchers hope that brainwave information can help patients with cerebral infarction and amyotrophic lateral sclerosis (commonly known as "ALS").
