Multi-Channel Sonification of Human EEG
MetadataShow full item record
The electroencephalogram (EEG) provides a diagnostically important stream of multivariate data of the activity of the human brain. Various EEG sonification strategies have been proposed but auditory space has rarely been used to give cues about the location of specific events. Here we introduce a multivariate event-based sonification that, in addition to displaying salient rhythms, uses pitch and spatial location to provide such cues. Using clinical recordings with epileptic seizures we demonstrate how the spatio-temporal characteristics of EEG rhythms can be perceived in such sonifications.
