Brain-controlled interfaces (BCIs) translate brain signals for controlling external devices, offering new hope for immobilized individuals. Advances in BCI technology promise to bring these powerful tools from the lab to clinical practice soon.

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Rehabilitation Technology

Background:

  • Brain-controlled interfaces (BCIs) offer a potential solution for restoring communication and movement in immobilized individuals.
  • Current BCIs utilize electrical signals recorded from the scalp, brain surface, or cerebral cortex.
  • These signals are translated into commands for prosthetic limbs and computer interfaces, with emerging somatosensory feedback.

Purpose of the Study:

  • To review the current state and future directions of brain-controlled interface technology.
  • To highlight the importance of technological advancements in translating laboratory BCI successes to clinical applications.

Main Methods:

  • Review of existing brain-controlled interface technologies and their signal acquisition methods (scalp, surface, cortical).
