This Is Your Brain on Sex: The Science Behind the Search for Love Reprint Edition

Every book is written from a perspective. This one is from the perspective of a divorced mother of a five-year-old who is still quite interested in sex and/or marriage. Kayt Sukel is a thoroughly modern woman. She is career-oriented and successful. She has made a mark in the highly competitive world of authoring articles for quality magazines, and with this she makes her book debut.

Although her mastery of the science of sex sets her apart, Sukel's thinking is quite mainstream for modern American campuses. There is nothing that will challenge prevailing views. She starts out by defining love. Rather, she discourses at length on how difficult it is to arrive at a single definition.

One theme that recurs in several chapters in his the idea that sexual love involves at least three separate elements. One is pure lust, which can most closely be explained by the brain chemicals, hormones and genetic factors that she describes. Second is the feeling of being in love, the butterflies in the stomach, distracted sort of feeling that comes of being head over heels. The third is the deep, long-term commitment.

She explains all of these through the use of diagrams of areas of the brain. Our reptilian brains are in control of our most basic functions, and more lately evolved portions drive the reasoning processes which channel and control the reptilian. Although it may not be interesting exactly which areas light up under which stimuli, the very fact that sexologists and neurologists can develop that accurate picture of what's going on in the brain is really pretty amazing. In her chapter on orgasm, she modestly presents a time series of images of her own brain as she was wired into an MRI. Scientists definitely have a clue what's going on in there.

All that said, the brain is a highly complex organ. There are large numbers of chemicals: oxytocin, dopamine, and serotonin to name three, each of which fills multiple functions. There are receptors for these chemicals, which may in turn do double duty, servicing two or more of them. Hormones govern the release of them, singularly or in groups. Even at a chemical level, it is difficult to arrive at definite conclusions. This is one of Sukel's strong points. She is content to describe the science as it stands, without feeling a need to stretch beyond what scientists know. In saying that scientists do not know what makes people fall in love, what makes love last, and what exactly pheromones are and do.

She talks about a rhesus monkey named Casanova was able to suppress his desire to mate in the interests of maintaining his social standing within a rhesus community into which he had been recently introduced. Not knowing the lay of the land, so to speak, he refused to get involved with the females came on to him. This is a very telling episode. It indicates that even in our primate relatives, and presumably our ancestors, reason and the upper hand over lust. We can control our emotions. She goes on to credit us with generally knowing when to keep our pants zipped and to avoid adventures that will jeopardize our relationships, our social standing and our pocketbooks.

Sukel's last chapter deals with love of divine beings, the love of God and others. It is curiously narrow. She talks about the way that love manifests itself in the individual - the same kinds of chemical and hormonal involvement as romantic love. She does not talk about it at all from the perspective of religious people. It is useful to note that fundamentalists preachers talk ad nauseum about the three Greek words for love: eros, filios, and agape, if I remember them right. One is romantic, the second is brotherly, and the third is love of all mankind. There is kind of a misfit here: she speaks of believers loving Christ as a person, whereas Christians speak of three different ways of loving one another, but no special way of loving Christ except "with all your heart."

The question of how religious people love is interesting because however misguided their beliefs, religious people seem to be the only ones who are successful in creating offspring and passing their beliefs on down to those offspring. Whatever one may think of Mormons and Muslims, one has to respect the fact that they breed true. The rest of us do not. This is a factor which is not even discussed in Sokel's book. I think it is relevant: the evolutionary purpose of sex is actually procreation, not self-fulfillment or recreation. If you do not have offspring, and do not raise them to have their own offspring, your seed dies out. There is some kind of love involved in the process. I doubt that it can be defined very well by hormones and chemicals, but I think that there is more research to be done on the higher functions of the brain involved in religious love, and then channeling Sokel's three forms of love - lust, romance and devotion - into the process of creating and nurturing the next generation.

In a book which refuses to take a strong stand on any issue Sokel goes out of her way to stress that the chemical reactions involved in homosexual love are pretty much identical to those in heterosexual love. She repeats the claim that gay people are pretty much that way from birth. This is the best supported statement of the claim that I have encountered. Her certainty on this one issue seems rather inconsistent with her refusal to take sides on other issues, but it does give strong credence to the gay community's claims.

With so much being written about neurobiology it is surprising that there is little available at this level. The straight forward approach and evolutionary flavor helps to put things in perspective. The author may get a bit too personal, but it certainly helps to know exactly what sort of sensation is being discussed. You will gain a much better understanding about what brain parts do what, but not much on the fine points of individual development.

Very good book covering the complicated relationship between our brains and the complicated way in which they affect with whom we fall in love, who are considered to be desirable sex partners, and how the complicated interplay between genes, gene expression, environmental effects all intertwine.

Fascinating book, and a good companion to the Scientific American on Love, sex, and the brain.

Sex and love are our favorite interests and mysteries. Kayt Sukel approaches the topics with considerable, and just enough old-
fashioned disarming honesty to keep the reader chuckling, as he learns about the neurotransmitters and hormones that fuel
the birds and the bees, not to mention the prairie voles! Great read. Happy with the author and the seller.

What is the nature of love (and its close cousin lust)? Kayt Sukel breaks it down both neuroscientifically and matter-of-factly. She shows us exactly what happens in the risk/reward part of the brain when we fall in love, fall out of love, make a baby, have a child, have an orgasm, parent, cheat, or decide not to.

There's a lot more to it all than estrogen, testosterone, oxytocin, and dopamine, but you'll get great insights into why (probably) we've evolved to behave the way we do when it comes to the objects of our affection.

This is a really fascinating subject (obviously) and an enjoyable read.

The neuroscience on sexual love is very helpful to process genuine reciprocal relationship with the opposite gender, giving proper place to sexual love as an expression of the foundation of unconditional positive regard that would undergird any expression of it.

This book is a great read and very informative. Both my husband and I read this and it gave a lot of material to think about and have some really informative conversations. Dirty Minds has been a great conversation starter with friends as well! Well worth the money and time!!!!!

I gave this book 5 stars without thinking twice. I enjoyed it immensely, and I learned a lot. BUT it must be said that if you read this book as being about love, you are going to be sorely disappointed, and probably not find it as funny or insightful. If you're reading it for some sort of sex thrill... you're not going to like it unless you've got a thing for rats. And if you do, you're gonna like this. Buy it, and then never go out in public again please. This is a book about neuroscience. Pure and simple. That said, it's a damn good one and you should read it.

This book is written in a style that will make you wish Sukel had written all of your science textbooks in high school (and even some of your college ones). Conversational tones applied to well-understood scientific concepts enable even a layman to work through the science-y parts without a thesaurus, a copy of Grey's, or a DSM. Further, most chapters have a fun little part where the concepts being scientifically discussed are put in motion in real-world examples. The end result is a reader who doesn't fully understand all the neuroscience, but understands the broad strokes, the implications, the questions that have been and can be answered and, more importantly, the questions that (as of now) cannot be.
