The study, published in the online journal Plos Computational Biology, found that four of the 13 patients with persistent vegetative state had a “robust” network of brain activity that would allow conscious thoughts, which was confirmed when they were asked to imagine playing tennis when their brains were scanned using a magnetic resonance imagining (MRI) machine.For the first six months of this blog in 2005, I was exclusively focused on the Terry Schiavo case and what it told us about THEORY AND ETHICS.
Previous work had shown that the “tennis test” could be used to show that some seemingly unconscious and uncommunicative patients with brain damage were in fact capable of understanding the request to imagine playing a game of tennis, which caused certain networks of brain cells to become active.
“We measured brain activity at rest and didn’t ask the patients to do anything. It showed that some unconscious patients with persistent vegetative state had robust brain networks that should support conscious awareness,” Dr Chennu said.
