The best solution is to avoid the ECG artifact in the first place. The problem is typically solved by adjusting the placement of the electrodes. Place the EMG electrodes so…
BIOPAC offers a variety of setups for recording electrodermal activity, including Reusable: skin conductance transducer (MP150+TSD203 or MP36+SS3LA) and electrodermal gel (GEL101). Disposable: MP150+EDA100C amp with 2 x LEAD110A or MP36+SS57LA EDA…
Here are some suggestions for overcoming the problem of stimulation artifact when applying a stimulation voltage to a muscle. Have the ground between the stimulating electrodes and the recording…
The “Electrode Check” port on the front panel of MP36 and MP35 units is dseigned to measure impedance. As a rule of thumb, impedance levels below 10 kOhms are ideal,…

The EOG100C amplifier can record from DC to 100 Hz and is designed to measure a signal correlated with the corneal-retinal potential (the small electrical potential difference between the cornea and…
Channel contention must be considered when connecting the analog output sourcing from external devices to an MP1X0 Data Acquisition System. Considerations for MP160 or MP150 users follow; MP100 users should refer…
In general it is much better to collect high quality data than to spend time and effort formulating methods to extract information from data riddled with artifacts. For advice on…
Only GEL101 (a solution designed to mimic the salt concentration of sweat) should be used with reusable skin conductance (electrodermal activity) recording electrodes. GEL101 electrode paste is specially formulated with…
Accuracy The degree to which something is true or exact. As an example, consider the characteristics of the TSD202A temperature transducer. With this transducer, there is an intrinsic accuracy of…
The terminology for electrical connections to human subjects is not universally agreed upon. “Ground” and “reference” are often used interchangeably. This is not a good practice as there are different…
When a single subject is connected via wires to a single MP system, there should generally be one and only one ground connection to that subject*. When multiple subject grounds are…
There are many possible reasons for a flat signal. It is important to make a distinction between the data (the numbers that the computer is actually recording) and the display…
Transducers developed by BIOPAC are linear over their expected ranges of operation. Therefore, knowing the system’s response to two physical stimuli is all that is required. In many cases the…
There are three areas of concern that must be considered in deciding the best way to synchronize stimulation/recording. Experimental need—the precision with which the timing of stimulus delivery events must…

When using electrodes: Prepare the electrode site by removing dead skin—unless recording EDA/GSR—using an ELPAD and cotton swabs with water. If recording EDA/GSR, see EDA (GSR) subject preparation for guidelines.…
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…
Models designed to infer stroke volumes based on changes in thoracic impedance rely on many simplifying assumptions. These assumptions are not universally valid. Consequently the relationship between measured impedances and…
On the MP100/MP150: For unipolar recording you need as many amplifiers as you have sites to record from. For example, for 16 electrodes (not including 1 reference and 1 ground),…
Our goal is generally to provide but not proscribe choices. As with electrode positioning, decisions about electrode type are best addressed via the literature and discussions with colleagues. That said,…
The best answers for this sort of question are found in the literature and via discussions with colleagues. Decisions about such things are matters of science, not technical support. In…
