Coordinated Activity in the Brain Measurements and Relevance to Brai
Increasing interest in the study of coordinated activity of brain cell ensembles reflects the current conceptualization of brain information processing and cognition. It is thought that cognitive processes involve not only serial stages of sensory signal

Preface The Numerous Aspects of Coordinated Activity in the Nervous System
It is reasonable to say that the ultimate goal of neuroscience is to understand how nervous systems, and brains in particular, process information. Whether it be a nematode or a primate nervous system, the foundation of information processing lies in the interactions between units, which in the case of nervous systems means neurons and glial cells. Each cell’s activity is meaningful only with respect to what other cells are doing. Hence, these multiple cellular interactions imply that some sort of coordinated activity must exist at some level. Synchronization of the cellular and network activities is one such aspect, and because of this, measures of synchronized activity are fundamental to the understanding of neuronal information processing. The search for methods and conceptual frameworks to capture coordinated activities in nervous systems has had a long history, as expressed by Varela and colleagues: “...since the
