Pharmacological modulation of anxiety-like behavior by flumazenil, midazolam, and ketamine in rats: Evidence from aversive ultrasonic vocalizations and elevated plus maze.
Sensorimotor gating is the ability of a weak sensory event to inhibit the motor response to an intense stimulus. Drugs that act as serotonin releasers, such as MDMA (3,4-methylenedioxymethamphetamine), impair sensorimotor gating, which is measured as a prepulse inhibition (PPI) of the acoustic startle response.
