Algogens such as capsaicin, bradykinin, acetylcholine, 5-hydroxytryptamine and potassium ions applied to exposed tail skin of the rat isolated spinal cord-tail preparation evoke a ventral root response consisting of depolarization and spiking activity. L-glutamate and kainate also evoke similar reflexes. All these compounds evoke depolarization of afferent(More)
The rat isolated spinal cord-tail preparation was used to examine the ability of peripherally applied excitatory amino acids to stimulate ventral root reflexes. Bolus applications (3 sec) of domoate (0.1-10 microM) or kainate (KA; 10-300 microM) to exposed skin of the rat tail stimulated ventral root responses comparably to those evoked by capsaicin (0.3-10(More)
NMDA channel blockers are potentially advantageous therapeutic agents for the treatment of ischemia and head trauma, which greatly elevate extracellular glutamate, because they should most effectively inhibit high levels of receptor activation. A novel high affinity TCP site ligand, WIN 63480, does not produce MK-801- or PCP-like behavioral activation at(More)
The rat isolated spinal cord-tail preparation has been employed to examine the effects of several antinociceptive drugs and excitatory amino acid (EAA) receptor antagonists on nociceptive reflexes (recorded in ventral roots) stimulated by peripheral application of capsaicin (CAP). Non-nociceptive monosynaptic and polysynaptic dorsal root-evoked ventral root(More)
