GSR Equipment

  • Currently there is a Biopac MP150 acquisition system installed at both scanners.
  • Each system is equipped with Biopac's GSR100C Galvanic Skin Response Amplifier.
  • Each system has all necessary MRI compatible leads and filters.

Current Hardware Settings

The Biopac GSR amplifier has several switches. The switches are typically set to the following values, which should be reasonable for general usage. Hardware switches should not be changed by individual users.

  • Gain = 5 micromho/V … for expected DC response between 0-50 micromho
  • Low Pass = 1 Hz … sufficient for almost all GSR studies
  • High Pass = Direct Current … no filtering provides absolute readings
