That is, an external stimulation, such as a painful stimulus, still activates "primary" sensory cortices in these patients but these areas are functionally disconnected from "higher order" associative areas needed for awareness.

[1] A mildly depressed level of consciousness or alertness may be classed as lethargy; someone in this state can be aroused with little ...
Because minimally conscious state is a relatively new criterion for diagnosis, there are very few functional imaging studies of patients with this condition. Preliminary data has shown that overall cerebral metabolism is less than in those with conscious awareness (20–40% of normal [3]) and is slightly higher but comparable to those in vegetative states.
