“…Recently, μ opioid and EP3 prostaglandin receptors were also found extensively in these “nociceptive” axodendritic system (Chamberlin et al, 1999; Engblom et al, 2000; Minami et al, 1994). Thus, the anti‐/pro‐nociceptive action of morphine and prostanoid inflammatory agents could be explained, at least in part, by a direct action upon the spino‐PB synaptic transmission (Huang et al, 1993; Matsumoto et al, 1996; Minami et al, 2001).…”

“…The CeA is the major amygdaloid nucleus receiving nociceptive information, especially through the spinopontoamygdaloid pathway (Bernard and Besson, 1990;Bester et al, 2000). This ascending nociceptive pathway is inhibited by opioids (Huang et al, 1993b). Although ␦ and opioid receptors are also located in the CeA (Paden et al, 1987), their roles in opioid analgesia have not been studied previously.…”

“…Indeed, numerous nociceptive specific neurons projecting either to the amygdala or to the hypothalamus were recorded in and around this ''nociceptive'' PB region, the responses of which were depressed by i.v. morphine in a dose-dependent and naloxone-reversible manner Besson, 1988, 1990;Huang et al, 1993;Bernard et al, 1994;Bester et al, 1995b). Furthermore, noxious stimuli evoke the expression of c-Fos protein in a portion of this latter ''nociceptive'' PB area (Bellavance and Beitz, 1996;Hermanson and Blomqvist, 1996;Bester et al 1997b;Buritova et al 1998) that receives a dense projection from nociceptive neurons located in the superficial spinal laminae (Burton et al, 1979;Wiberg and Blomqvist, 1984;Cechetto et al, 1985;Hylden et al, 1985Hylden et al, , 1986aPanneton and Burton, 1985;Light et al, 1987;Bernard et al, 1989Bernard et al, , 1995bBlomqvist et al, 1989;Slugg and Light, 1994;Craig, 1995;Feil and Herbert, 1995;Bester et al, 1995a).…”
