Brain Imaging Lets Vegetative Patient Communicate
February 4, 2010 | Source: Technology Review
A patient thought to be in a vegetative state was able to correctly answer a series of yes or no questions, with responses interpreted via functional MRI (fMRI) brain imaging, a study published today in the New England Journal of Medicine revealed.
Researchers aim to develop simplified, inexpensive alternates to fMRI such as EEG devices, and brain cognitive interfaces that will allow patients to interact with their environment.
