258 – BIOPAC MRI Smart Amplifier Performance

This application note is concerned with the recording of real-time physiological data, from a human subject, during fMRI, using BIOPAC’s series of MRI Smart Amplifiers:

These MRI Smart Amplifiers are designed differently than BIOPAC’s standard amplifier modules. MRI-specific amplifier modules feature internal circuitry which is designed to minimize MRI artifact (to the maximum extent possible) while still best preserving the amplifier bandwidth, phase, gain and signal to noise characteristics for the source physiological data.

Optimize Event-Related EDA

Electrodermal Activity (EDA) is an objective index for understanding emotional states. Researchers measure EDA to gain insights on psychological or physiological response, leading them down the path of scientific discovery. Because EDA is so important to research, BIOPAC has created tools to optimize event-related EDA analysis. Topics include: how to identify skin conductance responses, convert stim events from E-Prime SuperLab, Presentation, Vizard, etc., into AcqKnowledge events that can used for analysis, and score skin conductance responses using the AcqKnowledge automated EDA analysis tool.
