Using volume electron microscopy, Burkhardt’s lab identified 17 unique cell types in Mnemiopsis leidyi — 11 of which were previously unknown — in an all-important structure called the aboral organ (center). Together, these cells help ctenophores sense light, pressure, and gravity, and the aboral organ is tightly integrated with a continuous network of fused neurons that forms the nervous system. “Having more neurons condensed at a certain place, that’s one theory [for] how the very first brains evolved,” Burkhardt said. The research was published in March 2026(opens a new tab) in Science Advances.
