eevoke is a stimulation package for cognitive research that can present media such as images, sound or movies as stimulus to the patient or subject.eevoke runs on a PC with the Microsoft Windows XP operating system. Stimulus presentations can be visual, auditory or a combination of these. Besides, eevoke can be interfaced with external devices such as flash, electrical or pain stimulators. Trigger information is sent to external devices by means of serial or parallel port connection. eevoke provides optimal synchronization of the stimuli with your recordings and maximum ease of use. Using the eevoke package, stimulations are controlled through a scenario. Scenarios contain information regarding timing, response pads, event codes, and multimedia files. This way, both presentation and corresponding controlling information are running in parallel, yielding a highly flexible and adaptable environment for stimulation.eevoke supports dual-monitor display. This neat feature allows to run the experiment on the subject's display and at the same time monitor the stimuli as well as the reactions of the subject on a control display.
