The brain-computer interface (BCI) is a new technology that allows direct communication between the brain and an external device without going through the normal neuromuscular pathways. It can be used to detect and diagnose various brain disorders such as epilepsy and brain tumors, as well as restore impaired motor functions.Over the projected period, the worldwide brain-computer interface market is predicted to develop owing to an increase in the frequency of brain illnesses, brain tumors, and disability caused by stroke. According to Epilepsy Action Australia estimates from 2017, about 50 million individuals worldwide have epilepsy, with around 80% of them residing in emerging economies.
