In this article, the ongoing research in my laboratory,
regarding human pain perception and its representation in
the brain, is briefly reviewed. Most of our current studies
use fMRI to study the physiology and pathophysiology of
experimental and clinical pain states. Three main ideas are
introduced: 1) examining the temporal properties of pain
perception creates the opportunity to investigate and iden-
tify brain regions specifically involved in pain conscious-
ness; 2) this approach also leads to examining clinically
