Summary
This chapter introduces the reader to electroencephalography (EEG) including basic concepts, indications, limitations, placement of electrodes, instrument, display, parameters, calibration, safety, and the various types of EEG. EEGs are a commonly used test to evaluate various neurological conditions. Minute electrical potentials generated by neuronal synaptic activity in the superficial cerebral cortex can be detected by recording electrodes placed on the scalp, amplified, and displayed as electrographic waveforms on a screen. Subcortical structures such as the thalamus modulate this activity resulting in rhythms. EEGs can be used in a variety of different settings but like any test, have technical and practical limitations. Electrodes should be placed according to a standardized system, they should have low impedances, and the system should be bio calibrated before and after each recording. Safety and infection prevention protocols should be complied with while performing electroencephalography. [139 words/875 characters]
