Decoding the Brain: A Comprehensive Review of EEG Technologies in the Study of Human Brain Electrical Signals (KEY IJP************384)

• Mohar Singh Gurjar,Kamal Saini

Abstract

Electroencephalography by far is the most famous non-invasive instrument for real time analysis of brain electrical functions. It detects electrical signals through electrodes placed on the scalp and provides that instant window for the inside working of cognition. Winters, Emerson and Yang have made the EEG absolutely needed in emotion, workload and brain machine interface studies for revealing the neural mechanisms.The survey reports on recent developments in EEG technologies involving successes, limitations and future directions. It focuses on five pioneering research studies employing state of the art machines learning to decode emotion, task load, pain perception and intention from brain waves. Besides, the review outlines EEGs strength, weakness and promising landing zone for neuroscience and clinical applications as the technology possibilities become more manifest.
