Mind Reading Computer Could Communicate with Coma Patients

Canadian researchers have developing a mind-reading computer that could help communicate with people in a coma. 

The University of Western Ontario researchers used neuroimaging to read human thoughts via brain activity when they are conveying specific ‘yes’ or ‘no’ answers. The team say their research could lead to dramatic new ways of attempting to communicate with patients in a vegetative state.
 
In the study, participants were asked to concentrate on a ‘yes’ or ‘no’ response to questions like 'Are you married?' or 'Do you have brothers and sisters?' and only think their response, not speak it. By analyzing their brain activity, the team were able to accurately read their answers to a series of questions.

Their findings were published in The Journal of Neuroscience in a study titled, The Brain's Silent Messenger: Using Selective Attention to Decode Human Thought for Brain-Based Communication.

This is Your Brain on Jane Austen

Susan Celia Greenfield, Associate Professor of English, Fordham University and Public Voices Fellow with the Op-Ed Project, does research on Jane Austen. 

In a recent study of readers of Austen, it appears as if Austen is making news in the field of neuroscience

Here is an excerpt of a recent Greenfield blog post:
The Stanford Center for Cognitive and Neurobiological Imaging (CNi) has been tracking the blood flow patterns in the brains of Austen readers. How? By having literature graduate students read the second chapter of Mansfield Park while getting brain images using fMRI (functional Magnetic Resonance Imaging). The subjects were asked to alternate styles, reading some passages for pleasure and others with the kind of close critical attention required in literature courses like my own. The preliminary results surprised the researchers. Not only does close reading create a distinctly different blood flow pattern in the brain, but it also activates diverse regions that stretch far beyond those associated with attention, in one example, even reaching into areas generally dedicated to physical activity. You may think you are sitting still with a book. Your brain does not.

As it happens, Austen has a particularly effective technique for representing a character's consciousness (or for creating the fiction that such a thing exists). Known as free indirect discourse, or FID, the technique allows the narrator to enter a character's mind and adopt the language of her thoughts while retaining the objectivity of a third-person point of view. It is like a special lens that can simultaneously zoom inside consciousness and zoom out and see it from a distance. An MRI machine records activation in parts of the brain the subject isn't even aware of. FID represents aspects of a character's thoughts that the character herself does not know.

Such immersion in a character is one version of what Natalie Phillips, Assistant Professor of English at Michigan State University, and a co-director of the neuroscience study, describes as reading for pleasure. When she and her colleagues were first designing their experiment, they ran a pilot that put literature professors in the MRI. As Natalie explained to Laura Miller from Salon, "One thing we realized immediately... is that professors are terrible subjects!" On the phone with me she added, "We don't know how to read for pleasure anymore."

"And we definitely do not know how to do it in an MRI scanner!"
