  • When I was a kid I didn’t read about a “2nd brain” but a series of ganglions that acted like relays down the spine. Supposedly the belief was the size of dinosaurs made it impossible for nerve signals to reach the brain from distant parts of the body in a timely manner so they had these relays that made it easier to have reflex responses while the signal was being passed on to the brain.

    The idea stemmed from misinterpretations of large cavities found in the hip region of some dinosaurs, like Stegosaurus. This cavity, which appeared somewhat brain-shaped, was likely a glycogen body, a structure similar to one found in modern birds, and its purpose in dinosaurs is not fully understood but may relate to energy storage or balance.
