BCIA Neurofeedback & EEG 2

Question 1

Which EEG frequency band is most associated with deep sleep and delta-wave activity abnormalities in brain injury?

Accepted Answer

Delta (0.5–4 Hz)

Answer

Delta waves dominate during deep (stage 3) sleep and are pathologically elevated in waking states following traumatic brain injury.

Question 2

In QEEG (quantitative EEG), a Z-score compares an individual's brain activity against what reference?

Accepted Answer

A normative database matched for age

Answer

QEEG Z-scores express how many standard deviations an individual's EEG metrics deviate from a normative database matched for age and sometimes sex.

Question 3

The coherence measure in QEEG reflects what aspect of brain activity?

Accepted Answer

The degree of synchrony (phase relationship) between two electrode sites

Answer

Coherence quantifies the consistency of the phase relationship between two EEG channels, indicating the degree of functional connectivity between brain regions.

Question 4

Which EEG band is associated with active cognitive processing, problem-solving, and is often increased during mental tasks?

Accepted Answer

Beta (13–30 Hz)

Answer

Beta activity increases during active mental engagement, focused attention, and cognitive tasks compared to relaxed resting states.

Question 5

What is the 'Peniston Protocol' primarily used for in neurofeedback?

Accepted Answer

Substance abuse recovery via deep alpha/theta states

Answer

The Peniston Protocol uses alpha/theta training to induce hypnagogic states associated with positive imagery and emotional processing, primarily for alcoholism and PTSD.
