The normal stomach generates a myoelectric signal (EGG) that oscillates with a period of three cycles per minute. The EGG can be measured noninvasively by using the EGG100C amplifier and standard leads with disposable electrodes. After the data is recorded, the signal median frequency and power spectral density can be determined using AcqKnowledge. This type of signal processing is useful for evaluating abnormal gastric rhythms, such as tachygastria or bradygastria. It’s also possible to evaluate the EGG signal using the phase-space techniques associated with non-linear dynamics. Plotting EGG rate against a delayed version of itself in X/Y mode can point to patterns not otherwise evident in the time series data.

Eyes are the window to the soul and, more importantly, the brain. Psychophysiology, neuroscience, and consumer neuroscience researchers use eye tracking technology to understand emotion, behavior, subject response, decision-making, and human performance—and to help improve products and services. But not everyone knows where to start or how and why to use this important technology. A panel of eye tracking experts will present typical use cases and the latest eye tracking technology.
Watch this on-demand presentation with Q&A to learn the fundamentals of eye tracking!
Register NowCorrelating Driver Fatigue and Altitude Change In ongoing efforts to make our roads ever safer, frequent studies are published researching driver fatigue. In this study, researchers used wearable Eye Tracking technology and recorded eye movement, blink rate, and other physiological signals with the BIOPAC MP160 Data Acquisition Unit. The purpose of the study was to […]
