Wearable Electroencephalography(EEG): What is it, Why is it Needed, and What Does it Entail?

Electroencephalography (EEG) provides a noninvasive gateway to the human brain. Modern brain–computer interfaces (BCIs) provide a communication system that enables its users to send commands to a computer using only brain activity.

This brain activity is generally measured by EEG and processed using machine learning algorithms to recognize patterns in the EEG data.

Recent developments in wearable sensors have the potential to enable brain–computer and brain–brain networks that would revolutionize the way humans communicate. In this chapter we review BCI communication techniques and wireless BCI systems. We further specify the hardware and software required to enable brain–computer and brain–brain networks. Finally, we review state of the art wearable BCI systems and explore future possibilities in wireless BCI research.

Neurological diseases are the diseases of the spine, brain, and the nerves that connect them and provides oxygenated blood. The neurovascular systems are highly dependent on the continuous supply of oxygen and nutrients, which has been supplied by the arteries and veins. The amount of oxygen and nutrients to the brain is essential for its working; therefore, a defect in the system can impair the function, and it may quickly become a life-threatening factor.

The neurovascular diseases include hemorrhage stroke, ischemic stroke, brain tumors, and more. The genetic disorders, lifestyle habits, related chronic conditions may cause the development of neurovascular diseases. During the last few years, the predominance of neurological disorders has increased significantly. For instance, epilepsy is one of the neurovascular diseases that is rising significantly across the globe.
