Product Number: HMS-100

The standard CI Human Startle System is a turnkey hardware/software package designed to facilitate protocol design, collecting & storing data and viewing subjects' responses both real time and delayed time. All data are readily exportable to any spreadsheet application.

During the protocol phase, the user selects which stimuli will be presented on each trial. Any trial may include a pure tone and/or white noise stimulus and either may appear in the pre-pulse or startle stimulus temporal position. Blank trials (i.e., trials during which neither stimulus is presented) may also be included. For tones, the user specifies the duration, the amplitude and the frequency. For white noise, the duration and amplitude are specified by the user.

• Scalable Hardware & Software
• Automated Calibration
• Full-Power Acoustic Transducer
• Statistical Analysis
• Tone or Noise Prepulse
• Provision for Shock, Light, and other Stimuli

This program is provided to allow the user to make changes in system parameters for each installed module of the Human Measurement System and to test the hardware and subject connections before beginning any of the procedures.  Sound level calibration for the Startle module is accomplished here as is the testing of the integrators used for EMG channels in all software modules.  System parameters such as the sensitivity and offset settings are determined and recorded, and values for the software filters for the ECG are entered in the Utilities module.  Other features allow for testing all channels of the A/D converter and testing the subject devices (video splitter, mouse splitter, finger shocker).
