There probably is a significant base load and I don't think we can measure neuronal activity as well as we like to pretend. Imagine being consciously as good in trigonometry as your eye-brain... I believe size has an effect, elephants are pretty smart, and there is a general trend in the animal kingdom that would confirm this. Structural density is important too as well as type of brain matter. Some say humans are limited in head size because of birth. Look at how funny babies look with their disproportionately large head. But density is probably more an issue for humans than for elephants. The first deduction is probably ridiculous although we know that parts of the brain can be repurposed for other tasks if needed. We know there are completely functioning people that lost half their brain, just had to relearn some things.
