Arthur‐Ervin Avramiea – Pre-stimulus phase and amplitude regulation of phase-locked responses are maximized in the critical state (spotlight talk)

by Arthur‐Ervin Avramiea (Vrije Universiteit Amsterdam, The Netherlands). Understanding why identical stimuli give differing neuronal responses and percepts is a central challenge in research on attention and consciousness. Ongoing oscillations reflect functional states that bias processing of incoming signals through amplitude and phase. It is not known, however, whether the effect of phase or amplitude … Continue reading Arthur‐Ervin Avramiea – Pre-stimulus phase and amplitude regulation of phase-locked responses are maximized in the critical state (spotlight talk)

Shruti Naik – Richly Structured Event-Related Variability and its Development in Early Infancy (spotlight talk)

by Shruti Naik (Neurospin, Saclay & Aix-Marseille University, Marseille, France). The neural correlates of cognition have classically been studied by averaging the neural signal over many presentations of the same stimulus. The underlying hypothesis is that the average process recovers the stereotyped response evoked by each stimulus while the ongoing background activity, of larger amplitude … Continue reading Shruti Naik – Richly Structured Event-Related Variability and its Development in Early Infancy (spotlight talk)

Fabian Schubert – Local homeostatic regulation of the spectral radius of echo-state networks (spotlight talk)

by Fabian Schubert (Institute for Theoretical Physics, Goethe University, Frankfurt am Main, Germany). Criticality is considered an important property for recurrent neural networks. Close to a critical phase transition, RNNs show improved performance in sequential information processing. While the theoretical framework of reservoir computing provides a conceptual basis for the understanding of recurrent neural computation, … Continue reading Fabian Schubert – Local homeostatic regulation of the spectral radius of echo-state networks (spotlight talk)

Fabrizio Lombardi – Criticality in Sleep: From basic physiology to emergent brain dynamics (spotlight talk)

by Fabrizio Lombardi (IST, Klosterneuburg, Austria). Sleep periods exhibit numerous intermittent transitions among sleep stages and short awakenings, with fluctuations within sleep stages that may trigger micro-states and arousals. Despite the established association between dominant brain rhythms and emergent sleep stages, origin and functions of sleep-arousals and sleep-stage transitions remain poorly understood. Empirical observations of … Continue reading Fabrizio Lombardi – Criticality in Sleep: From basic physiology to emergent brain dynamics (spotlight talk)
