It supports many startle paradigms and has been used extensively in Schizophrenia and Posttraumatic Stress Disorder(PTSD) studies. The SR-HLAB™ Startle Response System used in human startle reflex testing is available in two basic models EMG or PEC. The EMG model measures the startle response by recording the eyeblink reflex via electromyography (EMG) using electrodes placed on the Orbicularis Oculi muscle. The PEC model measures the startle response by recording the eyeblink reflex using a Photoelectric Cell (PEC) to monitor the closing and opening of the eyelid. The basic system includes an integrated impedance meter(checks all electrode pairs at the same time), Integrated Control Circuit with external connector to control 12 V devices, an auditory stimulus module(white noise, 1 KHz or 1.2 KHz) and a Response Module of the appropriate type for the sensor being used; EMG or PEC. Additional modules for Heart Rate, Galvanic Skin Resistance, and Digital I/O can be added to the basic system. In some cases a second EMG or PEC module is added to compare the response between the left and right eye. If multiple response modules are used each response is recorded on a separate channel with all timing aligned. The included software through a simple menu system allows the user to define a test protocol. A test protocol contains Trials(discrete tests) that are then put into the Session definition, listed in the order the researcher would like the Trials executed. Trials control the delivery of the auditory stimuli and control when and how much response data is to be recorded. After a Session is completed the Data Reduction feature will take the raw data and create a tabular scored data file. Several parameters that affect scoring are set by the user. The scored data can be exported for use in statistical packages. The raw data is available for viewing and exporting. The raw data provides the user a method to verify that the scored
