How does Sacks see the theme of 'what science leaves out' play into the chapter? What does he thinks this leaves out?

Sacks argues that current neuroscience has trouble accounting for the role of higher cognitive faculties, and individual judgment specifically. As a result of leaving out this important element of cognition, neuroscientists are often out of touch with the reality of a patient's struggle and do not get a complete empirical picture of their patient. This covers the 'what science leaves out' theme by arguing that scientists often attend too much to the more mechanistic aspects of the mind and the brain.
