Reusable vs. disposable EDA/GSR electrodes

Reusable and disposable EDA/GSR electrodes both use isotonic gel but the formulas are different so results will be almost identical but will show a small difference.   The researcher should compare one electrode setup to the other during a measurement with a single EDA/GSR series amplifier. Disposable electrodes offer the advantage of using new electrodes for each recording, thus avoiding the issue of cleaning reusable electrodes.

New Citations | Stimulation and Mental Processing

Recent developments regarding electric stimulation and mental processing have lead to interesting developments in psychophysiology and physiological sciences. The following studies look at developments in how we potentially care for and understand solutions to issues with mental health, as well as new ways to monitor electrical stimulus on participants. The ventromedial prefrontal cortex (vmPFC) is […]
