To bridge preclinical research and clinical
investigation, we established a capsaicin pain heat fMRI
model in non-human primate with heat/42 C stimuli. We
hypothesize potentiation in heat-induced cortical
activation in response to capsaicin application at the
forearm will highlight the pain matrix depicted in
human pain fMRI experiments. Our results indicate that
group comparisons of brain activation between pre- and
post-capsaicin application show significant increases in
BOLD signals at the frontal, cingulate, precentral and
postcentral gyrus, and cerebellum (paired t-test,
p<0.002, n=8). Our data provide insights into
differentiating brain regions involved with pain-like
responses or thermal sensation.
