      Details
      This system was purchased from Resonance Technology Inc. It combines crystal clear, high-resolution digital video with high-quality digital sound to deliver unsurpassed realism. Dual-display stereoscopic video yields 3D images, which deliver visual paradigms that appear to emerge from the screen. The system also has an optional eyetracker module, with software that records ocular movement and synchronizes with EPI sequences. The 30dB noise attenuation headset reduces distracting gradient noise to ensure the subject can hear the intended stimuli. The built-in active noise-canceling microphone enables clear participant response with a minimum of background noise.
