The US military plans to develop "reading mind" to crack the EEG with a computer
Release date: 2008-08-22
For patients who have suffered brain injuries, such as stroke survivors or soldiers on the battlefield, communicating with doctors can be extremely challenging. In an effort to better understand their thoughts and improve treatment, American researchers are exploring the use of EEG technology to "read" what these individuals are thinking. This groundbreaking approach could potentially give a voice to those who are unable to speak.
A recent report from U.S. media highlights a study conducted by the University of California, Irvine. The research involves patients with limited verbal abilities who wear a special cap embedded with electrodes. These electrodes monitor brainwave activity, which is then sent to a computer for analysis. Scientists are working to decode the signals and determine the words that patients are mentally focusing on.
In the initial phase of the experiment, participants were asked to silently select a word from a list provided by the researchers. As they concentrated on their chosen word, the EEG captured the corresponding brain activity, allowing scientists to "read" their thoughts. Once this process was successfully demonstrated, the next step was to expand the range of possible thoughts. However, experts believe it may take several years before the technology can interpret more complex mental processes.
John Parker, one of the researchers involved in the project, emphasized that the current stage of the research is still in its early stages. The long-term goal is to develop a software system that can help brain-injured patients communicate without speaking, enabling them to express their ideas and feelings to others.
Despite the promising potential of this technology, there are concerns about its misuse. Since the $4 million funding comes from the U.S. military, some people worry that the same technology used to assist patients could be exploited for interrogative purposes. This raises important ethical questions about the future applications of mind-reading technology.
