Technology: Brain Interface

Brain-computer interface technology is a direct pathway for communication between the human brain and an external device.[1] BCI allows for bidirectional information flow unlike neuromodulation, which is the alteration of nerve activity through targeted delivery of a stimulus.[2] BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions.

brain–computer interface (BCI) also known as

  • neural-control interface (NCI)
  • mind-machine interface (MMI)
  • direct neural interface (DNI)
  • brain–machine interface (BMI)






In the Alien universe, this trope[3] is used in Alien The Cold Forge by Dr Blue Marsalis. As she suffers from a severe illness the use of her telepresence robot is the only way she can conduct her experiments. A variation on the BDI is the Neuro Visor in Prometheus which Sci-fi Interfaces has covered.
