C)neuron size
D)brain size

Question

Quizplus · Accepted Answer

Neural efficiency refers to how effectively the brain processes information, which can be inferred from the speed of the brain's electrical responses. Studies showing correlations between IQ and the speed of these responses suggest that individuals with higher IQs may process information more efficiently, hence the concept of neural efficiency.
