10 exam-style questions with answers and explanations, straight from our 1,030-question bank. Tap an answer to check yourself. When you're ready, take the scored version in the free practice test.
These 10 free BCIA-ACADEMIC-NEURO questions are organized by exam domain, so you can see how each part of the Board Certified in Neurofeedback (BCN) blueprint is tested. Reveal the answer and explanation under each question.
An irritating tone is removed whenever a participant meets the EEG criterion. Target attainment subsequently becomes more frequent. This is an example of which learning process?
Correct answer: C - Negative reinforcement
Why can a larger scalp EEG oscillation occur without an increase in average neuronal firing rate? Assume that electrode geometry and recording conditions are unchanged.
Correct answer: C - Greater synchrony of postsynaptic currents in similarly oriented cortical pyramidal cells.
An alert adult has an intermittent, arc-shaped 10-Hz rhythm maximal at C3. It remains visible when the eyes open but attenuates when the right hand moves. There is no behavioral arrest or other clinical change. How should this finding affect the recording?
Correct answer: C - Recognize a mu rhythm and continue the planned baseline recording.
An EEG digitizer is tested with a 60-Hz sinusoidal input, a sampling rate of 100 samples per second, and the analog anti-alias filter bypassed. Identify the apparent frequency in the sampled data and the measure that prevents this aliasing before it occurs.
Correct answer: B - 40 Hz; restore suitable analog anti-alias filtering before digitization.
A randomized ADHD study compares contingent EEG feedback with a credible sham condition. Participants and symptom raters remain successfully blinded. Only the contingent-feedback group learns to change the EEG target, but both groups improve similarly on the prespecified symptom outcome, with no demonstrated between-group advantage. Which conclusion respects the distinction between physiological learning and clinical efficacy?
Correct answer: A - EEG learning occurred without demonstrated symptom benefit over the sham condition.
A 70-year-old patient reports less anxiety but new mild drowsiness after a medication change. Compared with the earlier baseline, an artifact-free EEG shows more diffuse beta activity, not generalized slowing. Which newly started medication has the characteristic association with this combination?
Correct answer: B - Lorazepam
"He responds much faster now. Does that mean his attention has improved?" asks the parent of an adolescent completing follow-up testing. The same continuous-performance test requires responses to targets and no responses to nontargets. Under matched conditions, median reaction time has fallen from 480 to 360 milliseconds. Correct target responses are nearly unchanged, but responses to nontargets have risen from 7 to 22. The numbers of target and nontarget opportunities are unchanged. How should the clinician interpret the faster responses?
Correct answer: D - More commission errors suggest a speed-accuracy tradeoff, not unequivocal improvement.
Which configuration specifically implements traditional awake sensorimotor-rhythm training as an adjunct to medically managed epilepsy?
Correct answer: A - Reinforce 12-15 Hz over central sensorimotor regions during quiet wakefulness.
A proposed plan for a 12-year-old states: "The ADHD diagnosis indicates excess theta, so treatment will suppress theta until it is below the age norm." The diagnosis is well supported clinically. However, repeated alert, artifact-free recordings show age-typical theta and beta power and no elevated theta:beta ratio. The practitioner is reviewing the physiological rationale, not repeating the diagnostic evaluation. What correction is needed?
Correct answer: D - A normal ratio does not negate ADHD, but age-typical theta measurements do not demonstrate the excess being targeted.
A performance client discovers that tightening the forehead increases rewards during 20-30 Hz training. Raw EEG review shows irregular broadband fast activity that appears with the tension and disappears with relaxation. The client says, "I finally figured out how to win." Before the next block, the practitioner must ensure that the display rewards the intended neural feature rather than this new strategy. Which adjustment accomplishes that?
Correct answer: A - Gate out muscle-contaminated activity and coach relaxed, artifact-free target production.
