brain size

Cerebral volume measurement

Brain size refers to the physical volume or mass of a brain, typically measured in cubic centimeters or grams.

In scientific contexts, brain size is often discussed relative to body size, since larger animals generally have larger brains: Elephants have enormous brains, but relative to body size, humans rank higher.

The term appears in debates about intelligence, though the relationship between brain size and cognitive ability is complex and often misunderstood.
