Brain-Computer Interface

 

Brain-computer interfaces(BCIs) plays a significant role in spinal cord injury,stroke or brain disease.It also helps to restore senses like sight or hearing or even memory.

BCIs implemented in brain's motor areas can record electrical signals thats represents particular movements. A computer decodes the signals and uses them to control a computer cursor or prosthetic limb.

The device would replace part of the brain's hippocampus, where short-term memory is converted to long-term memory. So far researchers has had success in rats and monkeys, and now they are  currently testing the device in humans.
