Neuropeptide Y receptors in rat brain: autoradiographic localization.

abstract：:In the epileptic brain, hippocampal dentate granule cells become synaptically interconnected through the sprouting of mossy fibers. This new circuitry is expected to facilitate epileptiform discharge. Prolonged seizures induce the long-lasting neoexpression of neuropeptide Y (NPY) in mossy fibers. NPY is released spon...
