Assessment of long-term habituation correlates in event-related potentials using a von mises model

In our preliminary work we were able to demonstrate habituation by analyzing attention correlates in singletrial sequences of auditory eventrelated responses (ERPs). Despite dierent quantitative studies of instantaneous phase of ERPs in longterm habituation, there has been no former studies in generative process underlying the distribution of instantaneous phase information in the context of longterm habituation and its relation to attentional binding. For this means we used a von Mises model, representing the phase information over a set of single trial responses. Additionally we use a quantitative neurofunctional model to predict the dynamics of the instantaneous phase in singletrial ERP data during the longterm habituation. Measured habituation data is used to crossvalidate the model's prediction. We conclude that the described method allows for an assessment of dynamic changes in the course of longterm habituation. The results also reinforce our neurofunctional multiscale model of longterm habituation and show the applicability of the described method for the experimental/clinical neurodiagnostic assessment of attentional binding.
