For instance, it has been shown that naloxone administration reduces neural and behavioral placebo effects as well as placebo-induced responses in several cortical and subcortical areas that constitute the descending pain modulatory system (e.g., rACC, PAG, RVM, and hypothalamus).
Let us consider, then, the action neurotags that underlie movement sequences of dance in a dancer returning from injury: the desired movement outputs subserve the Newtonian and aesthetic requirements for the performance; however, a potentially broad array of modulatory neurotags that represent credible evidence of danger (for example, those neurotags that represent cues that the body part is broken, vulnerable, or weak) will influence motor outputs that subserve protection rather than performance.
Exceedance probabilities from BMA analysis of all endogenous connections, modulatory effects, and driving inputs from all participants were extracted and their significance was assessed using a one-sample t-test with Bonferroni correction for multiple comparisons.
As the study revealed the modulatory effects of the Z.
No statistically significant differences were observed, suggesting that non-cytotoxic concentrations were applied for the investigation of the modulatory effects of artichoke LE.
is due to the antioxidant and anti-inflammatory effects of key constituents such as rosmarinic acid, carnosol and the flavonoids which have previously demonstrated leukotriene, prostaglandin, nitric oxide and CYP modulatory activity.
Chapters in Part II relate to dorsal horn plasticity following injury; in Part III to anatomical and functional organization of ascending pain pathways; in Part IV to endogenous modulatory systems and in Part V to novel preclinical and clinical therapeutic strategies.
WAIKOLOA, HAWAII -- Duloxetine, a dual reuptake inhibitor of serotonin and norepinephrine, appears to have an effect on descending pain modulatory systems independent of its effect on mood, as demonstrated by significant pain reduction in diabetic neuropathy patients who are not depressed.

Whole-cell and cell-attached patch recordings were made from visualized CA1 interneurons and pyramidal cells in acute slices of rat hippocampus to investigate the modulatory effects of exogenous NE on GABAergic inhibition.
The common causes of neuropathic pain and treatment choices are discussed, and this section ends with a chapter devoted to pain modulatory systems.
Second, the activity of R15 can be altered by applying modulatory transmitters, such as serotonin (5-HT).
