"Synapses, the spaces between neurons, are the channels through which we think, act, imagine, feel, and remember. In short, they enable each of us to function as a single, integrated individual--from moment to moment, from year to year. Here, world-renowned brain expert Joseph LeDoux tells a groundbreaking and profound story: how the brain, and particularly its synapses, creates and maintains personality. Rather than taking sides in the age-old nature versus nurture debate, LeDoux illustrates how both contribute to synaptic connectivity and personality, broadening our understanding of who we are and what it means to be human."--Back cover.
