ost autistic children have an IQ of less than 70. They have major problems connecting socially to others and may, in severe cases, treat people like inanimate objects, neither greeting them nor acknowledging them as human beings. At times it seems that autistics don’t have a sense that “other minds” exist in the world.

Human beings exhibit an extraordinary degree of sexual plasticity compared with other creatures. We vary in what we like to do with our partners in a sexual act.

romantic love began to gain social approval in the aristocracies and courts of Europe only in the twelfth century—originally between an unmarried man and a married woman, either adulterous or unconsummated, usually ending badly. Only with the spread of democratic ideals of individualism did the idea that lovers ought to be able to choose spouses for themselves take firmer hold and gradually begin to seem completely natural and inalienable.

In Elizabethan times lovers were so enamored of each other’s body odors that it was common for a woman to keep a peeled apple in her armpit until it had absorbed her sweat and smell. She would give this “love apple” to her lover to sniff at in her absence.

we have two separate pleasure systems in our brains, one that has to do with exciting pleasure and one with satisfying pleasure. The exciting system relates to the “appetitive” pleasure that we get imagining something we desire, such as sex or a good meal. Its neurochemistry is largely dopamine-related, and it raises our tension level.
The second pleasure system has to do with the satisfaction, or consummatory pleasure, that attends actually having sex or having that meal, a calming, fulfilling pleasure. Its neurochemistry is based on the release of endorphins, which are related to opiates and give a peaceful, euphoric bliss.

We love being in love not only because it makes it easy for us to be happy but also because it makes it harder for us to be unhappy.

Evidence suggests that unlearning existing memories is necessary to make room for new memories in our networks.

Children are born helpless and will, in the critical period of sexual plasticity, do anything to avoid abandonment and to stay attached to adults, even if they must learn to love the pain and trauma that adults inflict.

Sherrington supported the idea that all of our movement occurs in response to some stimulus and that we move, not because our brains command it, but because our spinal reflexes keep us moving. This idea was called the “reflexological theory of movement” and had come to dominate neuroscience.

Normally, when we make a mistake, three things happen. First, we get a “mistake feeling,” that nagging sense that something is wrong. Second, we become anxious, and that anxiety drives us to correct the mistake. Third, when we have corrected the mistake, an automatic gearshift in our brain allows us to move on to the next thought or activity. Then both the “mistake feeling” and the anxiety disappear.
