Last Thursday, the American Museum of Natural History in New York City hosted “Neuroscience Night: Wild, Wild Brains” during Brain Awareness Week in the Spitzer Hall of Human Origins. The night was filled with interactive games and flash lectures (i.e., a series of talks no more than 30 minutes long) that showcased how our human brains compare to those of our animal counterparts, both present day and extinct.
Amy Balanoff, Ph.D., who was one of the night’s guest speakers, presented her own research on the evolutionary history of the avian (or, bird) brain. She and her colleagues use endocasts to study the brains of non-avian dinosaurs and Archaeopteryx (the first known transition between dinosaurs and flying birds) and then compare those casts to the brains of modern-day birds. An endocast is a casting of a hollow space—in this case, a fossilized cranial bone, which Balanoff created using CT imaging. Continue reading
