Effects of buprenorphine and methadone in methadone-maintained subjects.

abstract：:This study examined the role of the strychnine-insensitive glycine binding site of the NMDA receptor in prepulse inhibition (PPI) of the acoustic startle response (ASR) in rats. PPI is an operational measure of gating processes which normally lead to a diminished ASR when a startling stimulus is preceded by a weak pre...
