Neurogenesis, after being a target of harsh criticism and controversial overturn, has recently become largely accepted by the scientific community. It is now known that besides being born during embryonic and early postnatal ...

As living condition has been shown to affect rates of neurogenesis, the current study was designed to examine the relationship between neurogenesis and pain behavior, particularly stress-induced analgesia (SIA) and tonic ...

Pain sensitivity in 52 college male and female athletes and non-athletes was assessed at baseline and then after exercise and competition while workload was held constant. Subjects pedaled on a stationary bike for 20 minutes ...

The sharp decrease in pain sensitivity during and immediately following competition experienced by athletes is a quintessential example of stress-induced analgesia. While anecdotal evidence exists regarding this phenomenon, ...

In humans, social and physical pain are believed to arise from common neural networks, an evolutionarily advantageous system for motivating prosocial behavior. As such, the hypothesis that social insult can sensitize ...

Early life pain is known to cause long-term alterations, including a global reduction in pain sensitivity and decreased anxiety behaviors. An enriched environmentcharacterized by increased social interaction, exploratory ...

Neonatal pain has been shown to have long-term effects on pain behaviors, leading to increased pain thresholds, or hypoalgesia. Environmental enrichment has a significant effect on pain behaviors as well. The purpose of ...

The present study examined the effects of two social groups (romantic partners and best friends) on pain perception. Subjects underwent baseline and experimental pain testing days with the same procedure except subjects ...

Competition in both an athletic environment and the laboratory have been shown to produce analgesic effects. Gender interactions are present in these manipulations, particularly in the laboratory. The current study looks ...

Athletic competition elicits a stress response that is both physical and psychological in nature. Additionally, following athletic competition, an increase in pain threshold (analgesia) has been observed. However, the ...
