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