Is there a correlation between the size of an individual’s brain and level of intellect?

Generally speaking, there isn’t. Albert Einstein’s brain was smaller in size than average. There is synaptic connectivity, so the more you use your brain in creative ways, the more the synaptic activity increases. There’s a phenomenon called neurogenesis, which means you can grow, replace or regenerate neurons. Then there’s synaptic genesis. Mental activity remodels the brain.

Om Namah Shivay.
