Dissociation of hypertension and enhanced clonidine-induced antinociception in spontaneously hypertensive rats.

abstract：:In order to understand how nociceptive information is processed in the spinal dorsal horn we need to unravel the complex synaptic circuits involving interneurons, which constitute the vast majority of the neurons in laminae I-III. The main limitation has been the difficulty in defining functional populations among the...
