P. Marchettini et al., EXPERIMENTAL PAIN MODELS AND CLINICAL CHRONIC PAIN - IS PLASTICITY ENOUGH TO LINK THEM, Behavioral and brain sciences, 20(3), 1997, pp. 458
The central hyperexcitability observed in animal models supports a pat
hophysiological explanation for chronic human pain. Novel information
on cholecystokinin (CCK) upregulation offers a rationale for reduced o
pioid response in neuropathic pain. However, the basic information pro
vided by scientists should not lead clinicians to equate experimental
models to chronic human conditions. Clinicians should provide careful
reports and attempt to classify pathophysiologically clinical conditio
ns that have so far been grouped generically.
