All of these statements are true and reflect findings from research using PET scans and fMRI with patients in a persistent vegetative state. These imaging techniques have shown that some patients can exhibit varying degrees of cortical activity, including responses to personal stimuli like hearing their own names, and brain activity in response to pain similar to that of healthy individuals.
