Question

Which of the following statements about brain size is true?
A) Elephants have a larger number of neurons in their brain than humans do.
B) Octopods have a larger number of neurons in their brains than humans do.
C) The neurons in human brains are larger than the neurons in other primates' brains.
D) The brains of leaf-eating primates are larger than the brains of fruit-eating primates.
E) The ratio of brain size to body size is larger in baleen whales than in dolphins.

Accepted Answer

Elephants have a larger total number of neurons in their brains compared to humans, primarily due to their significantly larger brain size overall. However, it's important to note that a large portion of these neurons are located in the cerebellum, which is involved in motor control, rather than the cerebral cortex, which is associated with cognitive functions.
