Dr. Curtis Cripe: Possibility of a Brain-PC Interface

 
Researchers, scientists, neuroengineers, and more of the most brilliant minds on Earth are getting ever-so-closer to developing an interface between the human brain and a computer that can put people's thoughts in digitized form. As mentioned by NTL Group's Dr. Curtis Cripe in the past, this is especially helpful for people who cannot communicate, such as patients struggling with complete locked-in syndrome.

Leading specialists in numerous fields have tried to see if an interface that uses functional near-infrared spectroscopy, or NIRS, would work. Via this method, Dr. Curtis Cripe mentions that they would measure brain hemodynamic responses that are usually associated with neuronal activity. These specialists have also tried to use brain-computer interfaces that depend on neuroelectrical technology, such as an electroencephalogram or EEG. The endeavor ultimately failed in its goal of helping completely locked-in syndrome patients communicate.

However, many observers believe it isn't a complete failure since many people learned from it, says Dr. Curtis Cripe.

This latest technique, though, seemed to give hope to the study. It is a non-invasive brain-computer interface that combines NIRS and EEG technologies. This method measures frontocentral blood oxygen levels and electrical changes in the brain.

Dr. Curtis Cripe notes that brain-computer interfaces have helped patients communicate. The NIRS is the only technique that works on people with complete lock-in syndrome.

The fact that this is just the beginning also comes as very welcome news for people unable to communicate because of other health reasons. These are patients with amyotrophic lateral sclerosis or ALS, which can lead to paralysis later, or those paralyzed because of a stroke or a spinal cord injury.

The field of brain-computer interfaces is evolving at a rapid pace. Dr. Curtis Cripe, a renowned expert in neuroengineering, highlights that the possibilities for this technology are limitless and that there is so much to look forward to. With advancements in treating neurological disorders and brain injuries, there has never been a more exciting time for scientists and patients alike.

Dr. Curtis Cripe is the head of research and development at NTL Group, which consists of an international team of neuroengineers and neuroscientists from multiple disciplines to bring the latest in neuro technology and programs. In Dr. Cripe's series of posts here, he shares his insights on neuroscience, neuroengineering, psychology, and other related subjects.
