"Sept. 25, 2007 | In a recent article in the Archives of Neurology, a team of British and Belgian neuroscientists describe a clinically unconscious accident victim who can, on command, imagine herself playing tennis and walking around her house. By showing that her functional brain imaging studies (fMRI) are indistinguishable from those of healthy volunteers performing the same mental tasks, the researchers claim that the young woman's fMRI "confirmed beyond any doubt that she was consciously aware of herself and her surroundings, and was willfully following instructions given to her, despite her diagnosis of a vegetative state."
Their extraordinary conclusions are beyond provocative; they raise profound questions about the very notion of consciousness. What's more, they could throw thousands of families and doctors into utter turmoil. As with the Terri Schiavo controversy, patient advocacy groups, self-serving lawyers and politicians with personal agendas could use the study's stamp of certainty as a given.
Yet the study's conclusions are not beyond a doubt. There are plenty of questions about whether this young woman is conscious and capable of choice.
Let's briefly look at the study. In mid-2005, a 23-year-old woman sustained massive head injuries in an auto accident. Following multiple brain surgeries and five months of rehabilitation attempts, she remained unresponsive. According to her treating physicians, she could open her eyes but could not respond to any commands; she could not voluntarily look in the direction of a voice; there was no evidence of orientation or emotional response. They determined that she was in a permanent vegetative state -- a neurological categorization of patients who emerge from coma, appear to be awake, but show no signs of awareness of self or environment.
Before the recent advances in functional brain imaging, most neurologists, based upon their bedside observations and brain wave studies, would have agreed that the woman, though "awake," was extremely unlikely to have a significant private mental life -- either in terms of personal awareness or willful mental activity. (This failure to differentiate between awake and aware was a major feature of the Schiavo affair.) But new tools bring new opportunities; her doctors wondered if the fMRI could provide additional understanding of the clinically unresponsive brain. What if the fMRI could demonstrate residual consciousness and self-awareness, perhaps even the ability to respond to commands?
Their proposed study was quite simple. While inside an fMRI scanner, the unresponsive woman was asked by the researchers to perform three mental tests: relax, imagine playing tennis, and imagine walking around the various rooms in her home. The tasks were chosen because of their ability to activate different areas of the brain. Imagining playing tennis would light up the supplementary motor area, a region involved in imagining as well as performing coordinated movements. In contrast, imagining moving from room to room in a house activated those regions, such as the posterior parietal lobe, that contribute to imaginary or real spatial navigation.
At first glance, the results are startling. The patient was able to activate the same general brain regions as conscious volunteers serving as controls in the test; according to the authors, the images were statistically indistinguishable."
