Understanding the pattern structure of EEG signals would provide us with a key to unlock further understanding into neural dynamics. In this seminar I will demonstrate this principle using two types of data:
1) Steady state visual evoked potentials (SSVEP), studied both using ERP averages and single trial analysis.
2) Temporal structure of the signals recorded from patients with neurodegenerative disorders in rest conditions.
The structural organization (which elements are relevant) and associated functional role (how these elements play a role in brain dynamics) of electroencephalographic (EEG) oscillations are still far from being completely understood. Let us consider the separation of such oscillatory activities into background (or ongoing) potentials and transient burst pattern activities. The background EEG is constituted by regular waves, whereas bursts are transient and with higher amplitudes, with specific time-frequency properties. These bursts are organized local activities, most likely to be representative of local synchronies. How could we study their functional significance for cognitive neurodynamics?
