Event-Related Potentials (ERP) Analysis

Stim-Response Analysis

Present a variety of visual and auditory stimuli on one computer while AcqKnowledge records the stimuli event markers and psychological responses on another computer. As the stimuli are presented, the STP100W simultaneously (with 1ms resolution) sends trigger signals to the MP System for data synchronization and collection. The STP100W software (SuperLab) can be used to change the placement of visual stimuli on the screen, change the screens background color, choose from a variety of input and timing options, and provide feedback based on either response or reaction time. Different trigger channels can be paired to different visual or auditory stimuli to perform sophisticated evoked response averaging tests (e.g., P50, N100, P200, N200, P300, N300, N400, P600). The off-line averaging function in AcqKnowledge displays the averaged response to each different stimulus triggered from the STP100W system.  Use an MP System with AcqKnowledge software and the STP100W to record and analyze event-related potentials.
