Common Challenges of EEG Analysis
Though EEG signal detection provides a key indicator for detection of neurological status and disorders, its biomedical application is limited. This is because of the complicated nature of EEG signal and the complexities regarding the interpretation of the signals. Some of the challenges of EEG analysis are discussed as follows: Artifacts The recordings of physiological…

Electroencephalogram (EEG)
The brain generates rhythmically potentials which originate in the individual neurons of the brain. These potentials get summated as millions of cell discharge synchronously and appear as a surface waveform, the recording of which is known as the electroencephalogram. The neurons like other cells of the body are electrically polarized at rest. The interior of…
