Course Questions Pt 4 Flashcards
Which of the following is true about Differential Amplifiers?
A. The two incoming action potentials are added together and averaged, creating the raw EEG output.
B. The signals that are the same are rejected and only those that are different will be retained.
C. The signals that are different are rejected and only those that are the same will be retained.
D. A differential amplifier uses only one input.
B. The signals that are the same are rejected and only those that are different will be retained.
True or false: After the signal is amplified with the Differential Amplifier, the signal is free from artifacts.
False

False
Merzenich’s study in 1984 involved the amputation of the owl monkey’s third digit of their hand. What does this study show?
A. The areas originally associated with the third digit have the potential to regrow over some time.
B. A cortical map organization is malleable and can change as a result of a change in the somatotropic organization.
C. The somatosensory cortex can change only after the area associated with the digit is injured.
D. Sensory inputs are specific on the cortical map, regardless of deprived input.
B. A cortical map organization is malleable and can change as a result of a change in the somatotropic organization.

B. Sensitive period
C. Neuronal movement
D. Compensation
D. Compensation
Incorrect Neurofeedback training can result in Iatrogenic adverse effects (i.e headache, increased agitation, difficulty sleeping, increase in depression or anxiety, difficulty with cognition, foggy thoughts, dizziness, etc.). Because of this, it is important to:
A. Request the client to abstain from medication use due to the synergistic effect.
B. Be able to recognize the potential side effects of Neurofeedback and constantly reevaluate the training process throughout the training.
C. Ask the client to stay in the clinic for two hours after the first session to measure the client’s response.
D. None of the above, Neurofeedback rarely has adverse side effects.
B. Be able to recognize the potential side effects of Neurofeedback and constantly reevaluate the training process throughout the training.
When encountering a client who experienced adverse effects to Neurofeedback treatment, you should:
A. Suggest the use of medication to reverse the effects before there is a permanent neurophysiological change.
B. Stop the treatment immediately and refer the client to another practitioner.
C. Report the case to the Professional Standards and Ethical Principles board.
D. Stop the treatment and counter it with a different training protocol.
D. Stop the treatment and counter it with a different training protocol.
You have just completed the introductory EEG course. When you begin to use Neurofeedback with clients, a client who has been diagnosed with epilepsy presents for brain training. You have no experience in the assessment or treatment of epilepsy. What should you do?
A. Train the client regardless of experience.
B. Under the consultation of a BCIA certified mentor, you can treat this condition.
C. Refer the client to a BCIA licensed professional who has experience treating epilepsy.
D. Only after reading research about recommended protocol treatments can you treat the client.
C. Refer the client to a BCIA licensed professional who has experience treating epilepsy.
How can a practitioner assess the effectiveness of the Neurofeedback treatment?
A. Communicate one-on-one with the client using client self-report
B. A periodic questionnaire rating symptomatic severity
C. Continuous Performance Test (CPT)
D. All of the above
D. All of the above
When terminating treatment, which of the following is NOT true?
A. The clinician should communicate to the client the reasons behind the termination.
B. BCIA professionals should only continue Neurofeedback services as long as the client benefits from training.
C. If the client requires an intervention the clinician is not qualified to provide, the clinician should terminate the treatment and provide no further intervention.
D. Many state laws require clinicians to refer the client to at least 3 licensed colleagues.
C. If the client requires an intervention the clinician is not qualified to provide, the clinician should terminate the treatment and provide no further intervention.
