Recent years have shown an increasing interest in the development of neuro-feedback systems for intracranial EEG experiments and clinical applications. Such systems may, for example, allow stimulus manipulation in response to certain characteristics of the real-time neural signal. They are of great importance for testing the predictions about the functional role of neural oscillations of various frequencies found in EEG signals. In collaboration with the research group of Dr. L.M. Talamini (Brain and Cognition program, University of Amsterdam) we have developed a neurofeedback extension for EventIDE (our stimulus presentation software) that allows designing experiments, where stimulus presentation is accurately locked to a selected phase of the online EEG signal. Below, you can see a demo of EventIDE phase-locked stimulus presentation made over a real EEG recording.
