Startle / Fear potentiated Startle

The fully computerized TSE Startle Response/PPI test system is designed for accurate and reliable determination of the startle reflex and investigation of sensorimotor gating in rodents. In "PPI" (pre-pulse inhibition) experiments a weak prepulse is followed by the startle stimulus inducing a reduced startle response.

Animals are restrained in small cages restricting major movements and placed on species-specific measuring platforms with integrated high-precision sensors in sound-attenuating isolated cabinets. The flexible software package allows the creation of user-defined protocols including complex "pre-pulse" designs. Reaction time, i.e. response latency, and startle amplitude for each trial are presented in results tables. Graphs allow the performance of several animals to be compared.
