Knowing yourself now requires the understanding that the conscious you occupies only a small room in the mansion of the brain, and that it has little control over the reality constructed for you.
David EaglemanWhen one part of the brain makes a choice, other parts can quickly invent a story to explain why. If you show the command "Walk" to the right hemisphere (the one without language), the patient will get up and start walking. If you stop him and ask why he's leaving, his left hemisphere, cooking up an answer, will say something like "I was going to get a drink of water."
David EaglemanAfter all, across the population there are slight differences in brain function, and sometimes these translate directly into different ways of experiencing the world. And each individual believes his way is reality.
David EaglemanA mere 400 years after our fall from the center of the universe, we have experienced the fall from the center of ourselves.
David EaglemanWhen a male vole repeatedly mates with a female, a hormone called vasopressin is released in his brain. The vasopressin binds to receptors in a part of the brain called the nucleus accumbens, and the binding mediates a pleasurable feeling that becomes associated with that female. This locks in the monogamy, which is known as pair-bonding. If you block this hormone, the pair-bonding goes away.
