Resumé: In order to study the most subjective cognitive functions, we need to interact directly with them. From a neuroengineering perspective, this means that we need a technology allowing us to monitor and interact with cognitive functions in real-time. We will investigate a novel paradigm: the cognitive brain-computer interface. EEG signals have been shown to contain information correlated to cognitive functions (see e.g. Gazzaniga, 2009), which could be observed even in single trial acquisitions, for instance using time-frequency representations (Vialatte et al., 2007; Vialatte et al., 2009). Our working hypothesis is that it is possible to monitor the markers of such cognitive activity on short time scales (between 0,1s and 10s) with sufficient reliability. The goal of this research project is to monitor the neural correlates of cognitive functions in real-time. We will specifically study the local and large-scale synchrony effects (time-frequency structure, complexity measures, stationarity and non-linearity measures, mutual information, coherence and correlation, state-space based synchrony, etc.), as they are likely to convey key information about the neural correlates of cognition. These investigations will be performed within the boundaries of real-time constraints.
