Abstract
Brain-machine interface (BMI) is a novel device that allows the translation of brain activity like action potentials in the neurons into commands and data that can be processed by machines and used. In the hope of helping neuromuscular patients with their severe disabilities, research has rapidly increased on BMIs in the past decade and a half. BMIs have been demonstrated to control robotic limbs, wheelchairs, computer cursors, and even allowed patients that are unable to talk to synthesize speech through them. In this review article, BMIs will be reviewed from its definition to the different types, invasive or noninvasive
