Major clinical endpoints of general anesthesia, such as the alteration of consciousness, are achieved through effects of anesthetic agents on the central nervous system, and, more precisely, on the brain. Historically, clinicians and researchers have always been interested in quantifying and characterizing those effects through recordings of surface brain electrical activity, namely electroence...
Recent research emphasizes that majority of brain disorders and psychiatric problems are accompanied by disruption in the temporal structure of brain activity. From this perspective, disruption is viewed as a disorder of the metastable balance between large-scale integration and independent processing in the brain, in favor of either independent or hyper-ordered processing. This paper proposes ...
THE brain, like the heart, produces electrical waves during life. Caton, an English physiologist, was the first to measure these electrical potentials in the exposed brain of the rabbit (1875).1 It was not until 1929, however, that Hans Berger,2 a German psychiatrist at J ena, picked up electrical waves from the human brain by means of needle electrodes inserted into the scalp, and recorded the...
