| Abstract: | Owen et al. (Brevia, 8 September 2006, p. 1402) claimed that a patient's brain activity revealed that she was consciously responding to commands despite being in a vegetative state. However, several alternative explanations were not eliminated. Specifically, the activity could reflect unconscious reactions to the last word in the command, not conscious decisions to respond. A refined experimental design could clarify these issues. |
