Neural mechanisms underlying nociception and pain perception are considered to serve the ultimate goal of limiting tissue damage. However, since pain usually occurs in complex environments and situations that call for elaborate control over behavior, simple avoidance is insufficient to explain a range of mammalian pain responses, especially in the presence of competing goals. In this integrativ...

Although previous studies have suggested that depression may be associated with inhibition of evoked pain but facilitation of spontaneous pain, the mechanisms underlying these relationships are unclear. The present study investigated whether the difference between evoked and spontaneous pain on sensory (descending inhibition) and affective (avoidance motivation) components contributes to the di...

Previous research indicates that men typically tolerate more pain in experimental settings than women. One likely explanation for these group differences in pain tolerance is conformity to traditional, gender group social norms (i.e., the ideal man is masculine and tolerates more pain; the ideal woman is feminine and tolerates less pain). According to self-categorization theory, norms guide beh...

BACKGROUND The Patient-Reported Outcomes Measurement Information System was used to evaluate the effects of open incisional ventral hernia repair on hernia-related pain. METHODS All patients who underwent elective repair of a primary or recurrent midline incisional hernia over a 3-year period completed Patient-Reported Outcomes Measurement Information System pain surveys and rated their pain ...

Many patients with chronic pain also exhibit elevated levels of health anxiety. This study examined the effect of health anxiety on the use of safety-seeking behaviors (SSBs) in pain-provoking situations. Participants were 20 chronic back pain patients with high health anxiety (Group H), 20 with low health anxiety (Group L) and 20 pain-free controls (Group C). Two physical tasks were video reco...

background: ghrelin is a peptide with attenuating effect on inflammatory pain. both anti- and pro-inflammatory mediators have a role in the nociception and development of pain and hyperalgesia. il-10 and tgf-β are anti-inflammatory cytokines and inhibit the expression of pro-inflammatory cytokines related to peripheral and central inflammatory pain. in this study, the effects of i.p. injection ...

The role of amygdaloid glutamatergic receptors (GluRs) in maintenance of the sensory versus emotional component of neuropathic pain was studied by assessing monofilament-induced limb withdrawal response (sensory pain) and aversive place-conditioning behavior (emotional pain) following amygdaloid administration of various glutamatergic compounds in nerve-injured animals. The results indicate tha...

OBJECTIVE Minor illnesses and major diseases are affected by individual, environmental, and social factors. We sought to determine if children's temperament and pain reactivity (individual response styles) measured in kindergarten are related to future health behavior. METHODS Seven-year follow-up measures of health behavior were gathered in 42 children (mean age M = 11 years) who participate...
