The MMBS includes a state of the art system from BIOPAC (MP160) with smart-amp sensors for collecting electrodermal activity (skin conductance levels), electrooculogram (EOG), electrocardiogram (ECG), respiration, continuous blood pressure, Trans-Radial Electrical bioimpedance Velocimetry (TREV ), facial electromyography (EMG), and accelerometry. All signals are time-synced to stimulus presentation and incoming EEG data via a 4-channel optical diode trigger. This system includes an advanced scent delivery system (SDS200-SYS) capable of delivering up to 7 stimulus- or time-locked scents (dry or oil-based) which are then rapidly cleared from the room via a carbon air filtration fan. In addition, we can record responses from participants via joystick, keyboard, microphone, squeeze ball, camera, and mouse.
