TREND - Overview
For applications where prolonged EEG recordings are required, special NeuroSpeed modules are available. The NeuroSpeed TREND module includes a compressed display of selected recorded channels. This offers an easy detection of periodes with enhanced or reduced EEG activity, allowing to zoom in the actual EEG details as required. Another valuable tool delivered with the NeuroSpeed TREND module is the density spectral array capability (DSA). The DSA trend presents a colour coded time compressed overview of changes and distribution of frequency composition of the EEG in question. A similar trend capability is offered for coherences. In sleep applications the TREND module delivers a compact overview of sleep events such as apneas, arrousals, and PLMs.
