It would be advisable to have, as soon as possible, a baseline established by you or a student counting various behaviors at this time. That is, the vocal utterances, their frequency and duration, her movements (head, hands, eyes glancing around the room, etc.). Do this for different hours for different days to account for sleepiness, food input, blood sugar levels, etc. Then after that continue talking to her about patients who recovered by, without knowing how, remapping lost functions to different available parts of their brain. Be specific, inventive, and explain how coordinated movement could be recalculated by previously latent parts of the brain. Add, eye focus, facial expression, etc. One at a time each day add another. Continue the behaviors data counts.
