Biopotentials

The ability to easily record and measure a variety of physiological responses is a key requirement in polysomnography. Some of the standard physiological processes measured in modern sleep research include biopotential signals (EOG, ECG, EMG, EEG). The recorded biopotentials are used to measure and quantify different stages of sleep.

With data acquisition solutions from ADInstruments, you have the ability to record a broad range of signals and simultaneously display and analyze them in real-time. Tie this in with the ability to easily integrate and synchronize biopotential recordings with event markers from your stimulus presentation software, and you have a comprehensive and flexible solution that can grow with your research.

Signals Supported

ECG

With electrocardiography, alterations in the activity of the sympathetic nervous system due to emotional and cognitive states can influence heart-rate.

EEG

Record the electrical activity of the brain that occurs between pairs of electrodes in contact with the scalp and represents the sum of a large amount of underlying neural activity.

EMG

Electromyography (EMG) is the study of muscle electrical activity. Useful in recording reflexes and reaction times through to fine facial movements in response to stimuli.

EOG

Eye movements can be recorded using electrodes placed in the skin near the eyes. This includes such as tracking moving objects, fixating on stationary objects while the head moves, or measuring the direction and size of eye movements.

Flexible Data Acquisition

ADInstruments systems provide an integrated solution to advance life science research. With the combination of LabChart analysis software and a PowerLab data acquisition unit you have the flexibility to collect and synchronize a wide range of signals for analysis. We also offer a range of LabChart compatible solutions able to stream directly in LabChart.
