23 Απρ 2010 · The psychophysical threshold of pain triggered by Adelta-fibers was always higher (2.5-3 degrees C) than that triggered by C-fibers. The initial skin temperature did not influence these...
Definition. Pain threshold is defined as the lowest stimulus intensity that reliably elicits the perception of pain. Attention as well as motivational and emotional factors are known to influence the pain threshold that can be measured in the laboratory.
Definition. Pain threshold is defined as the minimum intensity of a stimulus that is perceived to be painful. Previously, this threshold was believed to be uniform across individuals, such that given intensity of a stimulus was thought to produce a given pain response.
1 Σεπ 2011 · In this article, mouse models of acute mechanical and thermal pain and inflammatory, visceral, and neuropathic pain are discussed. These behavioral measures can be used to phenotype transgenic mice for target validation and mechanistic studies, as well as to screen potential analgesic compounds.

It is reported that pain threshold in dorsal root ganglion neurons (DRG), which relay peripheral sensory information to the central nervous system, can be modulated by mechanisms involving a specific cluster of microRNAs (miRNAs).
