The auditory stimuli can be combined with tactile stimuli (air puffs) to form user-defined trial sequences with variable inter-stimulus intervals. For assessment of fear-potentiated startle an electrical stimulus (up to 3.1mA) can be applied using the integrated shock grid. The system also provides a TTL signal (digital signal) that can be used to switch on a camera or a video tape recorder or to control additional external devices such as user-specific signal generators. The flexible profile editor allows all standard tests to be created including complex "pre-pulse" designs to measure excitatory and inhibitory effects on startle.
