"The quintessence of this book is whether there possibly exist brains (central nervous systems) on other planets that might work the same or entirely differently from those found on Earth. ... For astro-neurobiological educated guesses, surmises, and ideas, this book is the first of its kind and offers a good read." (P. Chapman-Rietschi, The Observatory, April, 2016) "The illustrations are excellent, and there is an extensive bibliography. Most of the subjects are covered in many other books, but the discussion of neurosystems is original and insightful. Summing Up: Recommended. General readers, lower- and upper-division undergraduates." (T. Barker, Choice, Vol. 52 (12), August, 2015)
