[A program for control of competitive stimulation for inducing evoked potentials]

The Standard method of eliciting event-related potentials, the "oddball" paradigm, is insufficient as the sole technique for more differentiated problems. We therefore developed a more complex yet, in terms of variation of the stimuli, more flexible, method-competitive stimulation. This method also employs a two-stimuli paradigm, but uses independently delivered identical target and non-target stimuli with spatial separation. Since this technique requires special control mechanisms for the delivery of the stimuli, in particular with respect to the observance of time intervals between consecutive stimuli, we designed a software control program for the stimulation. This program can be run on any PC and permits great flexibility in the choice of the stimulus parameters and peripheral stimulating systems.
