Scientists are starting to discover how the cuttlefish's brain functions closely to human's by giving them 3D stimulus tests, and right in time for the Mulan remake to come out.
For the past three years, independent scientists conducted a study for the scientific journal; Science Advances. Four dedicated scientists built a program that tested the ocular capacity of the cuttlefish, in an attempt to test the brain functionality of the world's most intelligent invertebrate.
These scientists theorized that, unlike any other invertebrate, cuttlefish were able to see in 3D, which is a brain function that's typically reserved for creatures that are comprised of more advanced protein structures, like rabbits, and people.
This test for depth perception not only brought us closer to understanding the evolution of the brain in other species, but it also brought us closer to understanding one of the strangest creatures on Earth.
Cuttlefish are the most intelligent invertebrates, as aforenoted, but their brains don't function the same way as human brains do.
Unlike human brains, cuttlefish have non-segmented lobes, which means that there are no individual locations of the brain that were pre-determined to serve specific functions. Humans, for instance, have the ability to discern some feelings from other feelings, like the difference between physical pain and emotional pain. Cuttlefish don't have brains that have the capability to differentiate certain emotions from others, but we have just recently figured out that they can perceive depth better than most creatures with spines.
The three years' worth of experimenting actually broke ground in the invertebrate research community, and this was a huge step for understanding smooth vs. multi-lobed brains.
