This study examined the distribution of serotoninergic (5‐HT) immunoreactive axonal
contacts on spinal laminae I and II neurons by combining the intracellular horseradish …

Serotonergic pathways from brainstem to spinal cord play an important role in the
modulation of pain perception. To establish where that modulation occurs, we examined …

Physiologically characterized lamina I projection neurons, including antidromically activated
spinomesencephalic and spinothalamic tract cells, were intracellularly stained with HRP and …

Electrical and chemical stimulation given in the ventral medullary raphe nuclei inhibits spinal
nociceptive reflexes and spinal nociceptive transmission; serotoninergic receptors have …

Serotoninergic projections to the spinal dorsal horn are implicated in the modulation of
nociceptive transmission. However, morphological evidence indicating that serotoninergic …

Serotonergic axons in the superficial dorsal horn were examined at the light and electron
microscopic levels using an antibody specific for serotonin (5-HT). Immunoreactive 5-HT …

Neurons in the rostral ventromedial medulla (RVM) are the major source of serotonergic
projections to the dorsal horn. A large body of evidence implicates RVM serotonergic …

Through combined ultrastructural localization of ENK immunoreactivity and [3 H] 5-HT
uptake sites, it was found that 5-HT radiolabeled axons contact ENK immunoreactive cell …

The present study examined whether the effect of stimulation of the nucleus raphe magnus
(NRM) is mediated by spinal cord dorsal horn serotonin1A (5-HT1A) receptors in the rat …
