Introduction

BioSemi equipment is mainly used for measuring EEG, but can also be used for measuring ECG and EMG (usually in combination with EEG). Data is usually recorded with the Actiview software. See here for instructions on doing EEG research with BioSemi equipment.

Markers

To analyze EEG data, markers that signal the onset of certain events need to be sent from stimulus presentation pc to the BioSemi device. See for more information on sending markers the pages Sending Markers in E-Prime and Sending Markers in OpenSesame and the Markers and Events page for more information on markers in general.
