Brain-Machine Interfaces

 

Brain machine interfaces (BMI) are technologies designed to directly record brain signals or stimulate brain networks.  CIBR researchers are investigating two different interface technologies. One uses implanted devices and one uses devices placed on the surface of the brain. Implanted devices use electrical engineering, neuroscience, and neural engineering principles to design and fabricate devices that will provide for long-time recording of neural signals. These devices are being developed to provide command signals for amputees that need to control an artificial limb; high spinal cord injured or locked-in patients (e.g. patients suffering from strokes or Amyotrophic Lateral Sclerosis) to directly interface with a computer through cursor movement or writing software. The functional performance of these devices is being studied in laboratory animals with plans to translate their use to clinical applications within the next several years. Brain surface devices (electrocorticography, or ECoG devices) are used clinically today for several neurosurgical procedures, especially those associated with intractable epilepsy. Investigations are taking place to better understand the signals recorded from these devices to determine their utility for BMI.
