BRAIN MACHINE INTERFACES: a ray of hope

Neuroscientists have long relished the possibility of using brain signals to control artificial devices. Already, in literature there are several devices such as brain-actuated technology, neuroprosthes or neurorobots collectively refer as hybrid brain machine interfaces (HBMI) [1]. The word hybrid means a continuous interaction between living brain and artificial electronic devices. HBMI uses mainly in two types of applications
