We overfocus on brain volume, when we should be calculating the number of neurons and neuron size varies wildly.

I can't find the original video, but Suzana Herculano-Houzel developed a technique to measure total neuron counts by liquefying the brain and then counting the cell nucleus density / volume.

This paper is really fun, "Brains matter, bodies maybe not: the case for examining neuron numbers irrespective of body size" https://www.semanticscholar.org/paper/Brains-matter%2C-bodie...
