Thermal nociceptive properties of trigeminal afferent neurons in rats
BACKGROUND Although nociceptive afferents innervating the body have been heavily studied form many years, much less attention has been paid to trigeminal afferent biology. In particular, very little is known concerning trigeminal nociceptor responses to heat, and almost nothing in the rat. This study uses a highly controlled and reproducible diode laser stimulator to investigate the activation ...

Background and purpose : Muscle spindle is responsible for the control of skeletal muscle fibers function at rest and movement cycle, and is known as servo agent for voluntary movement. Function of this kinetic neceptor is completely dependent on the γ- ring activity would bring activity of la fiber and group ÏÏ spindle muscle afferent. Âlso, there is close functional of muscle relationship b...
متن کاملExpression of the transient receptor potential channels TRPV1, TRPA1 and TRPM8 in mouse trigeminal primary afferent neurons innervating the dura
BACKGROUND Migraine and other headache disorders affect a large percentage of the population and cause debilitating pain. Activation and sensitization of the trigeminal primary afferent neurons innervating the dura and cerebral vessels is a crucial step in the "headache circuit". Many dural afferent neurons respond to algesic and inflammatory agents. Given the clear role of the transient recept...
متن کاملUpregulations of P2X(3) and ASIC3 involve in hyperalgesia induced by cisplatin administration in rats.
The role of ion channels expressed in sensory neurons on mechanical and thermal hyperalgesia was examined in a rat model of cisplatin-induced peripheral neuropathy. The rats were injected with 3mg/kg of cisplatin intraperitoneally once per week for five consecutive weeks. The von Frey test, pin-prick test and plantar test were performed to examine any noxious sensitivity of the skin. The Randal...
متن کاملMorphine directly inhibits nociceptors in inflamed skin.
Peripherally delivered opiates attenuate mechanical and thermal hyperalgesia in experimental models of inflammation, suggesting that activation of peripheral opioid receptors decreases the excitability of nociceptors in inflamed tissues. The current study examines the effects of peripheral morphine sulfate on response properties of sensory neurons in healthy and inflamed skin. Afferent units (1...
