	In addition to the cursor feedback paradigm, BCI2000 comes with a multi-purpose [[User Reference:StimulusPresentationTask\|Stimulus Presentation]] module.		In addition to the cursor feedback paradigm, BCI2000 comes with a multi-purpose [[User Reference:StimulusPresentationTask\|Stimulus Presentation]] module.
	This module ~~has~~ many of the ~~features of~~ dedicated programs like [http://www.neurobs.com/presentation Presentation] or [http://www.pstnet.com/products/e-prime/ e-Prime]. In BCI research, the BCI2000 StimulusPresentation module is often used for [[User Tutorial:Obtaining Mu Rhythm Parameters in an Initial Session\|an initial Mu rhythm session]]. Still, it has very good [[User Reference:Timing\|timing precision]], and thus makes its use suitable for a wide range of psychophysiological experiments such as the ERP experiments described [[User Tutorial:Introduction to the P300 Response\|here]]. In addition, it can be used in conjunction with the P3SignalProcessing module (which can average and classify ERPs) to provide real-time feedback to evoked potentials.		This module is able to deliver visual and auditory stimuli in user-defined or pseudo-random sequences, and may respond to input from external devices. Thus, in many situations, it omits the need for dedicated programs like [http://www.neurobs.com/presentation Presentation] or [http://www.pstnet.com/products/e-prime/ e-Prime].

	Once you clicked ''Set Config,'' the ''Start'' button will be active (assuming all parameters have been validated and accepted). Press "Start" to start a simulated feedback session. During the session, you will see a cursor that moves from the left to the right at a constant. You will also see one of two targets highlighted on the right side of the screen. Your task is to move the cursor up or down such that it hits the highlighted target. In simulation mode, you can move this cursor by moving the mouse cursor up and down. In BCI experiments, the subject's task is to use brain signals, rather than the mouse, to move the cursor.

In BCI experiments, the subject's task is to use brain signals, rather than the mouse, to move the cursor.

	The period during which the cursor moves from left to right is called a ''trial.'' During operation, a number of trials will follow each other. Many trials make up one experimental ''run,'' where each run usually lasts about 3-5 minutes. When the run is finished, BCI2000 will stop operation on its own, and the ''Start'' button will change to ''Resume.'' At that time, the corresponding data file has been closed. Clicking ''Resume'' each time, you may add as many runs to the current ''Session'' as you like. All runs within a session will be stored as separate files in that session's data directory.
