Computational neuroscience offers insights into the dynamical properties of the brain under different states of awareness. The classification of brain states is relevant not only for the multiscale investigation of circuits and full brain networks, but also clinically relevant for the diagnosis (and eventual treatment) of disorders of sleep and consciousness, and to identify novel targets for anesthesia.

The temporal and spatial features of activity patterns generated by the brain under different states provide information about the computations carried out by the brain during different states, and the mechanisms and dynamics underlying transitions across states. The joint effort of experimentalists and computational neuroscientists results in electrophysiological, imaging, and simulated data that span space-time scales, to provide unique insights into brain dynamics and novel explanations of observed phenomena, providing new possibilities for overcoming experimental limitations.

In this workshop we bring together a wide range of experimental and clinical approaches, analysis techniques and computational models, generating multimodal and multiscale data and simulations to characterize the spontaneous spatiotemporal activity of the brain, its responsiveness, complexity, and dynamical properties under different brain states. We also open to floor to discuss which are the main open questions in the field.
