This tool allows the presentation of multimodal stimulus while analyzing electroencephalogram and evoked potentials to investigate perception mechanism and to detect individually important information. Groups of stimulus (collections of 2 or more thematic patterns) are shown with specified probability.

The subsensory stimulus presentation mode with specified masking stimulus with longer duration of presentation is used, This mode helps to distract attention of a person being tested onto other images concealing the true purpose of a studies and the content of subsensory stimulus used.

All tools for making, editing and displaying stimulation scenarios using different modality types (visual and auditory) with specified parameters of presentation are provided.

The visual stimulus are video clips, single images, groups (sequences) of images and also sign-literal stimulus. Auditory modality stimulus are of the most common formats of audio files.

The absolute synchronization of stimulation and EEG/EP recording, together with the recording of all necessary event markers, allow obtaining the accurate data for objective analysis.

3 buttons manipulator is used for marking a response (pressing a button)of a person being tested to various stimulus .
