Question

Which of the following statements is true about brain-computer interfaces and brain-machine interfaces?

a) They only work in virtual reality.
b) They allow direct communication between the brain and external devices.
c) They are limited to motor functions.
d) They are ineffective for medical applications.

Answer 1

Brain-computer interfaces and brain-machine interfaces allow direct communication between the brain and external devices, enabling paralyzed individuals to control computers and other tools using their thoughts. The technology has made significant advancements, but it does have limitations that need to be considered.

Step-by-step explanation:

Brain-computer interfaces (BCIs) and brain-machine interfaces (BMIs) allow direct communication between the brain and external devices, enabling paralyzed individuals to control computers and other tools using their thoughts. BCIs can use EEG recordings or implantable electrodes to capture neural signals, which are then decoded by a computer and used to control devices like computer cursors or robotic arms. While the technology has made significant advancements, it does have limitations, requiring intensive training and sometimes brain surgery for implantation.
