Abstract:
In the first part of my presentation I will talk about the phase-oscillator approximation in neuroscience and its application to studying the formation of synchronized cell assemblies in neuronal networks, as well as two phenomena that are closely related to each other: stochastic synchronization and spike-time reliability. I will also present experimental results verifying some of the theoretical predictions. In the second part of my talk, I will present some recent results from my lab on how network oscillations, like those recorded with EEG or MEG, inform us about the structure of the network. In particular, I will show that networks that generate rhythms like those observed in EEG recordings from healthy individuals have a pronounced hierarchical structure, whereas networks generating rhythms like those observed in EEG from epileptic and, especially, schizophrenic patients are less hierarchical and display lower structural complexity.
