That’s if you’re counting the cerebellum, which doesn’t seem to contribute much to intelligence, but is important for controlling the complicated musculature of a trunk and large body.
By cortical neuron count, humans have about 18 billion, while elephants have less than 6, comparable to a chimpanzee. (source)
Elephants are undeniably intelligent as animals go, but not at human level.
Even blue whales barely approach human level by cortical neuron count, although some cetaceans (notably orcas) exceed it.
