Hypothesis-generating for cortical pain imaging; does not support clinical adoption of BOLD-based discrimination.
Do temporally distinct nociceptive BOLD responses in multiple somatosensory processing cortical areas discriminate small noxious stimulus intensity differences?
Multiple cortical areas exhibit temporally distinguishable responses to innocuous and noxious heat, with S1 uniquely capable of discriminating small differences in painful temperatures.
Moulton et al. (2004) studied this question.
