Abstract

Electroencephalography (EEG) is a form of non-invasive brain imaging that records electrical activity (EEG). It's an overview of where EEG came from, briefly. In this article, we also detail the various brain imaging methods now in use. The human brain's anatomy and physiology are the next topics covered, with the intention of defining some terms. It provides context for understanding its anatomy and functionality. In this section, we'll discuss how the electrochemical currents that are recorded by scalp electrodes actually form in the brain. The techniques, potential problems, and necessary tools for EEG acquisition are discussed in this work. In modern times, the term "Electroencephalogram" (EEG) has come to mean "a recording of electrical activity of the alternating kind generated by brain regions and made at the scalp surface using metal electrodes and conductive medium". EEG recorded with electrodes placed on the brain's surface is called an electrocorticogram (ECoG), while EEG recorded with a depth probe is called an electro gramme.
