Cedrus Corporation offers software and hardware solutions to present and detect the onset of stimuli and to send them to various recorders (e.g., EEG and eye tracking) simultaneously. In 1991, they released a stimulus presentation software (SuperLab) with a student-friendly, point-and-click graphical user interface that allows the design of complex behavioral and psychophysiological experiments without the need to program. Shortly thereafter, they began offering ergonomic, versatile desktop response pads for use in laboratory settings. Today, with the release of an MR-compatible response box (Lumina), Cedrus is proud to be the exclusive button response unit provider to the world’s leading suppliers of MRI accessories.
