Among biologists, the neuroanatomists have always prided themselves on having a particularly refined sense of aesthetics. It’s a conceit that might be expected in a science that depends so heavily on visual perception. Carl E. Schoonover’s book, Portraits of the Mind: Visualizing the Brain from Antiquity to the 21st Century (Abrams, $35), offers a pictorial testament to the artistry and artistic sensibilities of neuroanatomists. From the magnificent pen-and-ink drawings of Santiago Ramón y Cajal to the quasi-impressionistic imagery in a cross-section of the hippocampus of a “Brainbow” mouse (shown at right), Schoonover’s book presents scientific images of the brain as works of art. The book begins with three historical essays, which are followed by chapters covering different types of microscopic techniques, “electricity in the brain,” neural circuitry and brain function. It’s a beautiful idea for a book, and I wish it could have been presented in a larger format—the kind typically used for art books—to suit the sensibilities of the neuroanatomist in all of us.

"Penguins are 10 times older than humans and have been here for a very, very long time," said Daniel Ksepka, Ph.D., a North Carolina State University research assistant professor. Dr. Ksepka researches the evolution of penguins and how they came to inhabit the African continent.
Because penguins have been around for over 60 million years, their fossil record is extensive. Fossils that Dr. Ksepka and his colleagues have discovered provide clues about migration patterns and the diversity of penguin species.
