FMRI-BOLD responses were triggered by
(1) a painful nociceptive laser stimuli applied to the right foot,
(2) a non-painful tactile stimuli applied to the right foot,
(3) a brief visual stimuli,
(4) a brief auditory stimuli.
Can *you* guess which of these four BOLD maps corresponds to the "pain matrix" elicited by the nociceptive stimuli?
