eevoke - The stimulation package for cognitive research
eevoke is a universal and highly reliable stimulation package that can present stimuli with any kind of complexity in cognitive experiments. Stimulus presentation can be visual, auditory or a combination. Moreover, eevoke can be interfaced with external devices such as photic, electrical or laser stimulators. eevoke provides optimal synchronization of the stimuli with your recordings, high flexibility and maximum ease of use.
Easy to control
Using the eevoke package, stimulation is controlled through a scenario. Scenarios contain information regarding the timing and event codes of multimedia files, and define the sequence of trials and blocks in the experiment. Both presentation and corresponding control information are interpreted in real time, resulting in a complete and highly flexible environment for stimulation.
