NEUROFEEDBACK BCIA EXAM STUDY ACTUAL QUESTIONS AND
ANSWERS
Absolute Power - CORRECT ANSWER✅✅Measurement of raw energy output at each site during
recording compared to normative database.



Relative Power - CORRECT ANSWER✅✅Distribution of energy resources being utilized during recording
among the frequencies measured compared to normative database.



Amplitude Asymmetry - CORRECT ANSWER✅✅Average difference between signals measured
compared to normative database.



Coherence - CORRECT ANSWER✅✅Variability of neural activation and delay between sites compared to
normative database.



Phase Lag - CORRECT ANSWER✅✅Average of the delay between processing sites compared to
normative database.



Alcohol - CORRECT ANSWER✅✅Can increased beta and decrease thalpha and alpha.



Stimulants - CORRECT ANSWER✅✅Some increase in beta and possibly decrease in theta.



Caffeine - CORRECT ANSWER✅✅Suppress alpha and theta. Withdrawal may result in an increase in
alpha.



LSD & Cocaine - CORRECT ANSWER✅✅Both increase fast activity. LSD will decrease alpha; cocaine
tends to increase alpha.



Opioids - CORRECT ANSWER✅✅Increase slow alpha initially but followed by decrease in alpha and
increase in theta and delta.
