BCIA Neurofeedback & EEG 3

Question 1

In LORETA (Low Resolution Brain Electromagnetic Tomography) neurofeedback, what advantage does it offer over single-channel training?

Accepted Answer

It targets specific internal brain regions (source localization) rather than scalp surface signals

Answer

It is less expensive to implement

Answer

It requires fewer electrodes

Answer

It provides faster client feedback

Question 2

Eye blink artifacts in EEG recordings are caused by which physiological source?

Accepted Answer

The electrooculogram (EOG) from eyelid movement

Answer

Scalp muscle tension

Answer

Cardiac electrical activity

Answer

Respiration movement

Question 3

In neurofeedback training, an 'inhibit' band refers to which type of training goal?

Accepted Answer

Rewarding the client when the frequency band stays below a threshold

Answer

Increasing the amplitude of the target frequency

Answer

Providing no feedback for that frequency range

Answer

Using the band as a reference baseline only

Question 4

Neurofeedback training for epilepsy commonly seeks to enhance which EEG rhythm over the sensorimotor cortex?

Accepted Answer

SMR (12–15 Hz)

Answer

Theta

Answer

Alpha

Answer

High beta

Question 5

What does 'electrode impedance' of less than 5 kΩ indicate before a neurofeedback session?

Accepted Answer

Good skin-electrode contact ensuring clean signal acquisition

Answer

The amplifier gain is too high

Answer

The session can be skipped

Answer

The client is too relaxed

Question 6

Which hemisphere is typically dominant for language processing in most right-handed individuals?

Accepted Answer

Left hemisphere

Answer

Right hemisphere

Answer

Both hemispheres equally

Answer

The frontal midline only
