Display of prolonged EEG recordings.

An interactive minicomputer system for displaying, storing and providing hard copy output of prolonged EEG recordings has been described. Perhaps the most significant feature of the system is the versatility gained by using a minicomputer. The routines developed initially solely for the display and storage of the EEG have recently been readily modified to control a different playback unit. They also form an integral part of a software package being written to set up a data base for prolonged EEG recordings and also for the study of artefacts in ambulatory recordings.
