ABSTRACT
This chapter overviews the analysis of electrical brain activity for monitoring the functional status of the brain. Many control signals are initiated in the brain, which are then transmitted throughout the body to execute various bodily functions. Brain signals can be picked up by electrodes on the scalp, known as the electroencephalogram (EEG). The EEG signal arises from billions of neurons firing within the nervous system. These signals hold important information regarding the brain function and are affected by neurological conditions and other abnormalities. There are, for example, routine applications for the diagnosis and treatment of neurological disorders such as epilepsy. Recent research in EEG-based communication has also opened up exciting opportunities for restoring function in individuals with disabilities.
