Slight update – Nice things people have said about “The First Brain”

If you have read The First Brain, I would ***really*** like to hear from you, especially what can I do better. If you have any questions about it just leave a comment or send me an email at

A review at the place that ends in “-azon” would be great! Remember, I want to hear the good the bad and the ugly.
Thank you!


I feel so blessed!

If you are a reader of my blog, you know that my first book came out recently.  You’ll have to forgive me for incessantly talking about it.  After all, The First Brain is kind of my 4th child! (after these three beauties):

Not bad, huh?

Anyway, the thing is that I discovered that I love writing; I was not expecting to discover it at this stage of my life and I intend to enjoy it to the fullest. Please remember that TFB is a popular science book. I wrote it specifically with laypeople in mind; I hope everyone can enjoy it. I basically use flatworms as a vehicle to explain brain science and general neurobiology, as well as pharmacology…


I intend to keep writing even if nobody reads me. Of course, it is better if I am read, though, and one of the best rewards about it is when people, especially people you respect, have good things to say about your words. I am very grateful of the reviews left by readers at a website whose name rhymes with ‘-azon’, as I am of the reviews left by colleagues and established science writers. Here are some of them:

From the website that rhymes with “-azon:

“After reading the book I came away wiser with the knowledge of our evolutionary history. Dr. Pagan sheds light upon subjects that many of us take for granted–only to find that we have a deeper genetic history. It is not only fun to explore but will make us reflect on a more creative path. I could only wish that there were more books written similar to it. Highly recommended!”

“Professor Pagan takes us on a fascinating journey looking at these tiny flatworms, with their remarkable ability to regenerate and their astonishing longevity. This book has got something for everyone, including details about a curious experiment with zombie planarians. If you’re looking for an informative, enjoyable, easy-to-read non-fiction book exploring the origins of the brain, then I highly recommend The First Brain: The Neuroscience of Planarians.”

-Mr. Peter Cawdron, Author of:

Blogger at Thinking Sci-Fi

“This book is written in an engaging conversational style. Dr. Pagan entwines history, philosophy, scientific methods, and the joy of scientific investigation while clearly explaining the role of planarians as model animals for studying a variety of topics, such as regeneration, neurobiology, and pharmacology. This book can be read at many levels. If you want to go deeper into the topics, he provides helpful footnotes and an extensive bibliography.

I highly recommend this book, especially for budding scientists.”

Dr. Vida Kenk

From the back cover of TFB:

“There are few good books about the evolution of the brain, but this is one of those few — a journey along an ancient byway of the animal kingdom which shows just how blinkered and vertebrate-obsessed neuroscience has become. In The First Brain we learn that planarians have an array of frankly bizarre features with very real implications for the origins of our own cerebral majesty. By the end of this appealingly personal and reflective book, Pagàn has cogently argued that it is only by studying his favorite cannibalistic worm that we can truly understand ourselves.”

“Flatworms are about as alien to us as an animal can be, but they finally have an ambassador. Pagan’s engaging book walks us through why flatworms aren’t aliens at all, and why they have the distinction of being the first animals on Earth having a ‘brain.’ …A brain in many respects like our own.”

“Reading Oné Pagán’s The First Brain is a pleasure akin to sitting in the company of an especially engaging and erudite scientist as he tells of research (his own and others) on his favorite subject: in this case, the wondrous animals you and I call flatworms and biologists call planarians. Dr. Pagán’s enthusiasm for science, neurobiology and the aforementioned creatures is utterly contagious. If you begin the book (like me) not recalling exactly what a planarian is, you’ll close it wondering why you and everyone you know aren’t talking, thinking and writing about them all the time.”

In the Journal of Child Neurology:

“I highly recommend this book to any clinical pediatric neurologist, neuropathologist, or basic neuroscientist with an interest in evolution and who keeps an open mind toward novel phylogenetic perspectives of the origin of the human nervous system, in addition to the novel practical research opportunities provided by this unique animal.

In Foreword 1 of TFB:

“So remember back to when you were a child and you hadn’t heard the word science yet. You were just curious about who you were, what was around you, what everything else was. So you looked, poked, or whatever else you did, to fi nd out. Forget that this natural curiosity might have been lost, or suppressed, by school, by other demands, or by the seemingly imposing terminology of science. Want to get it back? Want to take up where you left off ? Want to feel like a kid again? Then just read this book. And, yes, it is okay to smile while reading a science book.”

TFB is available as an ebook (Kindle, Nook, as well as in iTunes). The price of the Kindle version was just reduced by Amazon… (:-)

The hardcover is available at Amazon and at the Oxford University Press’ website.  There’s even a 20% discount code from OUP.

This is a popular science book, which I hope to be enjoyed by laypeople and biologists alike.

I also wrote a science fiction story with an autism theme. I published it in two languages, check them out!
