摘要: Neurokinin 1 (NK1) receptors are involved in pain and anxiety behaviors animals, but little is known about central alterations this receptor system human pain. With positron emission tomography, using a [11]-Carbon labeled NK1 antagonist, we demonstrate attenuated availability frontal, insular cingulate cortex, as well the hippocampus, amygdala periaqueductal gray area patients with chronic The reduced was most pronounced ventromedial prefrontal cortex (vmPFC), where attenuations correlated to measures of fear avoidance movement. Further, vmPFC levels also displayed opposing influences compared controls on regional cerebral blood flow anterior cingulate. We conclude that altered results suggest modulate motor inhibition, contribute
