 Researchers at Maastricht University in The Netherlands have developed a device that gives a voice to those who are completely unable to speak or move at all. Building on previous work using functional magnetic imaging (fMRI) technology, which allowed individuals to give yes/no responses or answer multiple-choice questions, the new approach allows for full, unscripted back-and-forth conversations.

FMRI is a non-invasive technique that measures brain activity by detecting the changes in blood oxygenation and flow that occur in response to neural activity. It has previously been used to assess consciousness in people described as being in an unconscious, vegetative state and enable them to answer yes/no questions. This was then expanded to allow individuals to answer the equivalent of multiple-choice questions having four or fewer possible answers.

    In islam, the sick are sick because allah, mahound’s imaginary alter-ego, wants them to be sick. Black-cube worshippers might try to “heal” them by administering camel milk, camel pee and/or Mein Qurampf recitation, but they’ll be shunned and rejected by their fellow members of the “perfect race” (according to sura 3:110) if those “treatments” don’t work…. Shunned and rejected when they don’t end up getting beaten up for it.
