Scientific American Book of Love, Sex and the Brain

Who do we love? Who loves us? And why? Is love really a mystery,
or can neuroscience offer some answers to these age-old
questions?

In her third enthralling book about the brain, Judith Horstman
takes us on a lively tour of our most important sex and love organ
and the whole smorgasbord of our many kinds of love-from the
bonding of parent and child to the passion of erotic love, the
affectionate love of companionship, the role of animals in our
lives, and the love of God.

Drawing on the latest neuroscience, she explores why and how we
are born to love-how we're hardwired to crave the companionship of
others, and how very badly things can go without love. Among the
findings: parental love makes our brain bigger, sex and orgasm make
it healthier, social isolation makes it miserable-and although the
craving for romantic love can be described as an addiction,
friendship may actually be the most important loving relationship
of your life.

Based on recent studies and articles culled from the prestigious
Scientific American and Scientific American Mind
magazines, The Scientific American Book of Love, Sex, and
the Brain offers a fascinating look at how the brain controls
our loving relationships, most intimate moments, and our deep and
basic need for connection.
