SYNAPTIC SELF - HOW OUR BRAINS BECOME WHO WE ARE

Despite ongoing debate about the root cause of psychological disorders, most agree that the development of the self is central to the distinction between normality and psychopathology. Yet neuroscientists have been slow to probe the biological basisfor our sense of self, focusing instead on states of consciousness. LeDoux (The Emotional Brain), professor at New York University's Center for Neural Sciences, has come up with a theory: it's the neural pathways the synaptic relationships in our brains that make us who we are. Starting with a description of basic neural anatomy (including how neurons communicate, the brain's embryological development and some of the key neural pathways), LeDoux reviews experiments and research, arguing that thebrain's synaptic connections provide the biological base for memory, which makes possible the sense of continuity and permanence fundamental to a "normal" conception of self. Writing for a general audience, he succeeds in making his subject accessible to the dedicated nonspecialist. He offers absorbing descriptions of some of the most fascinating case studies in his field, provides insight into the shortcomings of psychopharmacology and suggests new directions for research on the biology of mental illness. While some may disagree with LeDoux's conclusion that "the brain makes the self" through its synapses, he makes an important contribution to the literature on the relationship between these two entities.
