Recent fMRI research suggests that at least some patients diagnosed as being in the permanent vegetative state can be more aware than it was previously thought.

In particular I consider whether having higher forms of consciousness must always be an additional reason against the withdrawal of life-sustaining treatment. In my paper I also highlight the general importance of cognitive science for the ethical evaluations of some medical practices.
