Vegetative state refers to the neurocognitive status of individuals with severe brain damage, in whom physiologic functions (sleep-wake cycles, autonomic control, and breathing) persist, but awareness (including all cognitive function and emotion) is abolished.

Recent functional neuroimaging results have shown that some parts of the cerebral cortex are still functioning in 'vegetative' patients. Such studies are disentangling the neural correlates of the vegetative state from the minimally conscious state, and have major clinical consequences in addition to empirical importance for the understanding of consciousness (Laureys, 2000). The minimally conscious state (MCS) is a recently defined clinical condition that differs from the persistent vegetative state (PVS) by the presence of inconsistent, but clearly discernible, behavioral evidence of consciousness (Boly, 2004). Researchers have analyzed functional neuroimaging results and demonstrated that cerebral activity observed in patients in an MCS is more likely to lead to higher-order integrative processes, thought to be necessary for the gain of conscious auditory perception. (Sara et al, 2007).
The syndrome was first described in 1940 by Ernst Kretschmer who called it apallic Syndrome.[1]
The term persistent vegetative state was coined in 1972 by Scottish spinal surgeon Bryan Jennett and American neurologist Fred Plum to describe a syndrome that seemed to have been made possible by medicine's increased capacities to keep patients' bodies alive.[2][3]
A 23-year-old woman in a vegetative state after a severe brain injury due to a car accident in 2005 was able to communicate with a team of British researchers at Cambridge University in England via functional magnetic resonance imaging.
