Animal Electroencephalography focuses on the use of electroencephalography (EEG) in studying brain electric activity. The manuscript first underscores the physiologic bases of EEG and the characteristics and usage of electrodes. Discussions focus on basic elements of nerve cell function, general nature of EEG, implantation of intracerebral electrodes, and affixing surface electrodes. The text then examines noise or artifact, electronic recording systems, and interpretation and analysis of EEG. Electronic principles of special relevance, electrode configurations, and electroencephalographs are discussed. The book takes a look at EEG correlates of physiologic and pathologic changes, as well as maturation of EEG, behavioral correlates, and internal influences. Experimentally produced brain diseases and naturally occurring brain diseases are also elaborated. The manuscript is a valuable reference for readers interested in electroencephalography.
