A brain–computer interface (BCI), sometimes called a direct neural interface or a brain–machine interface (BMI),
is a direct communication pathway between the brain and an external
device.It is a direct communication path between a either accept command
from the brain or send signals to it.Two way BCI would allow Brain and
external devices to exchange information in both directionsthe word
brain means the brain or nervous system of an organic life form rather
than the mind. Computer means any processing or computational device,
from simple circuits to silicon chips.Research on BCIs began in the
1970s, but it wasn’t until the mid-1990s that the first working
experimental implants in humans appeared.
