LeDoux believes the answer rests in the synapses, key players in the brain's intricately designed communication system. In other words, the pathways by which a person's "hardwired" responses (nature) mesh with his or her unique life experiences (nurture) determine that person's individuality. Here, LeDoux nimbly compresses centuries of philosophy, psychology, and biology into an amazingly clear picture of humanity's journey toward understanding the self.
Equally readable is his comprehensive science lesson, where detailed circuit speak reads like an absorbing--yet often humorous--mystery novel. Skillfully presenting research studies and findings alongside their various implications, LeDoux makes a solid case for accepting a synaptic explanation of existence and provides to the reader generous helpings of knowledge, amusement, and awe along the way. --Liane Thomas --This text refers to an out of print or unavailable edition of this title.

The book is well written, flows nicely until the near end,(drags a little just after chapter 6 however, that is why a 4 not a 5 rating) i'd recommend "synaptic sickness" be moved to an appendix if it couldn't be integrated into the body of the book better. The scholarly apparatus is kept to a minimum yet the push to ratify/justify the new knowledge via experimental data and reference to other scientists work is clearly evident and makes the book a good intro to the field, as further study is facilitated. I found the use of concrete experimental examples and the prolific use of diagrams (especially figures 6.4 - 6.6) particularly good(very superior), the book was always engrossing and a stimulating read, not common in books written by scientists who are not teachers as well.
As to particularly important ideas: i would point to chapter 6= "small change" and the systematic analysis of Hebbian plasticity and how long-term potentiation supplies the synaptic justification for memory and learning the key chapter in the whole book.Read more ›
LeDoux's Synaptic Self is a wonderful book loaded with clear understandable explanations and insights (his wife, a "fantastic writer," assisted) on how the brain works based on the most current neuroscience (e.g., how neurons/synapses/neurotransmitters/neuro modulators work/don't work, implicit/explicit learning/memory mechanism explanations, nature/nurture considerations, the "mental trilogy" of cognition/emotion/motivation, and much more). The book's bottom-line, he writes, is "you are your synapses." With this book, "know thyself," and even fix thyself, seem more attainable. It's a book I'll reread/study for a while.
The following are quotes from the last chapter:
Life requires many brain functions, functions require systems, and systems are made of synaptically connected neurons. We all have the same brain systems, and the number of neurons in each brain system is more or less the same in each of us as well. However, the particular way those neurons are connected is distinct, and that uniqueness, in short, is what makes us who we are.
What is remarkable is that synapses in all of these systems are capable of being modified by experience... Emotion systems [as an example]... are programmed by evolution to respond to some stimuli, so-called innate or unconditioned stimuli, like predators or pain. However, many of the things that elicit emotions in us or motivate us to act in certain ways are not preprogrammed into our brains as part of our species heritage but have to be learned by each of us.Read more ›
Ledoux concentrates on memory, having in his last book focused on emotion. He explains memory systems from molecules to circuits, with the classical and most recent findings, including some from his own lab. He also gives a quick overview of the emotional systems of the brain, the working memory complex of the prefrontal cortex, and motivational systems of neuromodulator and brainstem and thalamocortical systems. He calls that the mental trilogy, namely cognition, emotion and motivation. Ledoux also wrote a nice chapter on some brain diseases that seem to alter these functions selectively. And thats it. Ledoux has explained the self. Or has he? Well, memory, emotion, cognition and motivation surely contribute to the making of the self, especially memory. How much of a self is left in a retrograde and anterograde severe amnesic? But this is not saying that putting them together is all the self is about. Its like saying vision, attention and waking are what consicousness is.Read more ›
