Actiview is free open source software used for recording with BioSemi (mainly for EEG) equipment. 

Availability, support and advice

Actiview is available for researchers at FSW Leiden and comes preinstalled on all lab computers (see the Software List to check which version).


To analyze EEG data, markers that signal the onset of certain events need to be sent from stimulus presentation pc to the BioSemi device. These markers will be visible during recording in Actiview. 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.
