Open access fNIRS dataset: painful stimuli with morphine vs placebo

Normal subjects were subjected to electrical pain stimulation while under the influence of morphine or a placebo in a double-blinded study. fNIRS recordings were acquired from the medial prefrontal cortex, right somatosensory cortex and left lateral prefrontal cortex, revealing attenuation in activation in the medial Brodmann Area 10 associated with lower reported pain levels.
