Introduction to Electroencephalography

The book comprehensively examines the theoretical, methodological, and clinical foundations of electroencephalography as one of the leading methods for studying the functional state of the brain. It outlines the diagnostic, prognostic, and monitoring value of EEG, as well as its application in neurosurgery, functional diagnostics, psychophysiology, neuroscience, experimental psychology, and cognitive research. The place of EEG among modern brain research methods and its integration with neuroimaging techniques are emphasized.
The historical development of the method is reviewed-from early investigations to the era of full digitalization, the introduction of quantitative analysis (qEEG), source localization, and the implementation of artificial intelligence. The main EEG rhythms (delta, theta, alpha, beta), their functional significance, and age-related dynamics are described. Modern concepts of EEG genesis are presented, including the role of cortical neurons, postsynaptic potentials, thalamocortical mechanisms, neuronal synchronization, and the network organization of brain activity.
The book details EEG recording conditions, functional tests, technical aspects.
