Some men may be genetically inclined to have and hold a single partner, while some may not. In the near future, young women who stay current with the scientific literature may demand genetic tests of their boyfriends to assess how likely they are to make faithful husbands.

There is a looming chasm between what your brain knows and what your mind is capable of accessing.

Modern neuroimaging is like asking an astronaut in the space shuttle to look out the window and judge how America is doing.

Reductionism is not the right viewpoint for everything, and it certainly won't explain the relationship between the brain and the mind. This is because of a feature known as emergence. When you put together large numbers of pieces and parts, the whole can become something greater than the sum.

Brains are like representative democracies. They are built of multiple, overlapping experts who weigh in and compete over different choices.

In the traditionally taught view of perception, data from the sensorium pours into the brain, works its way up the sensory hierarchy, and makes itself seen, heard, smelled, tasted, felt - "perceived." But a closer examination of the data suggests this is incorrect. The brain is properly thought of as a mostly closed system that runs on its own internally generated activity.

At least 15 percent of human females possess a genetic mutation that gives them an extra (fourth) type of color photoreceptor - and this allows them to discriminate between colors that look identical to the majority of us with a mere three types of color photoreceptors.
