Comparison between delta-opioid receptor functional response and autoradiographic labeling in rat brain and spinal cord.

The distribution of delta-opioid receptors (DORs) in the rat central nervous system has been previously characterized by radioligand binding and immunohistochemistry. However, the functional neuroanatomy of DORs has not been mapped in any detail; this is potentially important, because these receptors appear to be primarily cytosolic. Opioid receptors can… CONTINUE READING
