This advanced course provides a background to Evoked and Event-Related Potentials (EP/ERP) and Slow Cortical Potentials (SCP) in neurofeedback. The course covers the use of specialized software display screens created for the Thought Technology Infiniti Instrumentation to record P300 responses, audio or visual evoked and event-related potentials, and slow cortical potentials, and view them using individual responses or multi-trial averages, with absolute or relative baseline. The course also provides an introduction to the use of the Infiniti software editors (Developer Tools) to create or revise the display screens specifically for use with evoked and slow cortical potentials.
