fMRI shows emotional reactions in vegetative patients

http://www.plosone.org/article/info:doi/10.1371/journal.pone.0074711

Using fMRI, Tel Aviv University and Sourasky Medical Center’s Haggai Sharon, Yotam Pasternak, Talma Hendler and colleagues have shown that the brains of patients in a vegetative state emotionally react to photographs of people they know, as though they recognize them.

“We showed that patients in a vegetative state can react differently to different stimuli in the environment depending on their emotional value,” said Dr. Sharon. “It’s not a generic thing; it’s personal and autobiographical. We engaged the person, the individual, inside the patient.”

Research focused on the “emotional awareness” of patients in a vegetative state is relatively new. The researchers hope to eventually contribute to improved care and treatment. They are also working with patients in a minimally conscious state to better understand how regions of the brain interact in response to familiar cues.
