A

True

54
Q

True or false:
The meta-analysis study by Cobin, Hammond and Arns, suggests that 19-channel Z-score Neurofeedback shows virtually no evidence that it is effective or superior in any way to any other forms of Neurofeedback.

True

55
Q

What does an epoch refer to?
[This was on the BCIA exam]

Q

What is optical isolation?
[This was on the BCIA exam]

A

In the context of neurofeedback, optical isolation refers to a method of separating or isolating electrical circuits or components to prevent interference or feedback loops between them. This ensures that there is no direct electrical connection between the input and output sides of the system, reducing the risk of electrical interference and feedback loops.
