Interpreting Electroencephalogram (EEG) – An Introductory Review of Assessment and Measurement Procedures

Abstract

This work aims to compile various measurement and calibration techniques for Electroencephalogram (EEG). The objective is to provide an assessment of different components of an EEG and their significance in understanding different types of responses to stimuli. This review provides an overview of recommended electrode positions and lead systems for EEG with calibration and activation procedures. The different components of an EEG according to frequency bands – Gamma, Beta, Alpha, Theta and Delta have been discussed with emphasis on their interpretation and their role in several applications. The motivation behind this study is to provide a basic understanding of the composition of EEG, understanding the significance of each brain wave and the locations at which they are most prominent.
