PVS- LIS- MIND READER-FMRI

////////////////////IMAGINE THE PLIGHT OF PRNTS OF NEURO-DISABLED PTS


/////////////////AWAKE , AND/OR AWARE- LIKE BEING BURIED ALIVE


///////////////////...........Professor Adrian Owen, research leader based at the University of Western Ontario in Canada and the University of Cambridge, has previously shown that a fifth of vegetative patients are actually conscious.


////////////////////This group of patients have all suffered brain injuries, usually as a result of a trauma such as a car accident, or perhaps after a stroke or viral infection.

They differ from so-called 'locked-in' patients whose brain function is intact but are paralysed and communicate usually through eye or small head movements.

With vegetative patients the brain injury causes sufficient damage to leave them with nothing but core reflexes and no higher cognitive function.


//////////////////////////////wiki=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 vegetative state. This diagnosis is classified as a permanent vegetative state (PVS) after approximately one year of being in a vegetative state


/////////////////////////Consciousness has two dimensions (Zeman, 2001): arousal or wakefulness (i.e., level of consciousness) and awareness (i.e., content of consciousness). Figure 1. In normal physiological states (green); level and content are positively correlated (with the exception of the oneiric activity during REM-sleep). Patients in pathological or pharmacological coma (i.e., general anesthesia) are unconscious because they cannot be awakened (red). The vegetative state (VS, blue) is a unique dissociated state of consciousness.

///////////////////////////////////ROM HOUBEN=The former engineering student and martial arts enthusiast, now 46, told Der Spiegel that he meditated to pass the long years trapped in his own body.


////////////////////////////Neural Correlates of Consciousness (NCC) can be defined as the minimal neuronal mechanisms jointly sufficient for any one specific conscious percept (Crick & Koch 1990).
