what is another term for persistent vegetative state
Persistent vegetative state A persistent vegetative state (PVS) is a disorder of consciousness in which patients with severe brain damage are in a state of partial arousal rather than true awareness. 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 some months (3 in the US and 6 in the UK) after a non-traumatic brain injury or one year after a traumatic injury. Nowadays, more doctors and neuroscientists prefer to call the state of consciousness an unresponsive wakefulness syndrome,[1] primarily because of ethical questions about whether a patient can be called "vegetative" or not.[2]
Encoding (memory) Encoding is a biological event that begins with perception. All perceived and striking sensations travel to the brain's thalamus where all these sensations are combined into one single experience.[11] The hippocampus is responsible for analyzing these inputs and ultimately deciding if they will be committed to long-term memory; these various threads of information are stored in various parts of the brain. However, the exact way in which these pieces are identified and recalled later remains unknown.[11]
