Surely not? Wouldn't a mammal and lizard brain of the same absolute  
size have quite a different amount of cortical folding (favouring the  
mammal)?

I imagine a large lizard (like a Komodo monitor) and a small rodent  
could possibly have the same brain volume - I also imagine the  
monitor's brain would be far less convoluted.
