Why study brain-behavior relations?
– Brain-imaging to see what regions are active during
specific mental task
– Record activity of cells to determine what activity makes
– Present information to different hemispheres and see
which side does task better or faster

Persistent vegetative state
A persistent vegetative state is a disorder of consciousness in which patients with severe brain damage are in a state of partial arousal rather than true awareness. It is a diagnosis of some uncertainty in that it deals with a syndrome. After four weeks in a vegetative state (VS), the patient is classified as in a persistent (or 'continuing') vegetative state. This diagnosis is classified as a permanent vegetative state (PVS) some months after a non-traumatic brain injury (3 months in the US, 6 months in the UK, or one year after traumatic injury). Nowadays, more doctors and (neuro)scientists prefer to call the state of consciousness an unresponsive wakefulness syndrome, primarily because of ethical questions about whether a patient can be called 'vegetative' or not.
