Many studies in the past tried to test the hypothesis that exogenous ERP components may be due to a phase reset of ongoing oscillations (Başar, 1999; see also Van der Lubbe et al., 2016). Recently, several related models have been proposed like the ERPR model (Klimesch et al., 2007), and the Firefly model (Burgess, 2012). One of the ideas of the ERPR model is that the phase-reset of specific oscillations may depend on the type of task, which may therefore lead to a different ERP waveform. Goal of the project is to focus on intra-individual EEG differences by measuring a single subject in long sessions and to use different classes of stimuli and tasks. The acquired data will shed more light on the validity of the Phase Reset model, and the possibility that phase reset of specific oscillations is task-specific. An additional goal of the project is to develop an alternative perspective that is based on resonance. The latter model may explain why there may be actually be an increase in the strength of ongoing oscillations after stimulus onset.
