Effects of deprolorphin, a casomorphin analog, on hippocampal CA1 field potentials in vitro.

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...
