Found : Modern brain’s ancient roots in marine worms

With no room for discussion or Q&A, a press release from European Molecular Biology Laboratory asserted, “Modern brains have an ancient core.” How ancient? At least as far back as the marine ragworm. Continuing the confident assertions, it went on to say, “Multifunctional neurons that sense the environment and release hormones are the evolutionary basis of our brains.”
The article says that neurons in this centipede-resembling annelid worm secrete hormones.
