Review: There’s No Hiding the Success of Incognito: The Secret Lives of the Brain - Introduction The success and popularity of David Eagleman’s newest book Incognito: The Secret Lives of the Brain is no secret. This humorous yet stimulating book explores the exciting world of our unconscious mind and all its contradictions. Eagleman is a prominent neuroscientist and director of the Laboratory for Perception and Action at Baylor College of Medicine, where he also directs the Initiative on Neuroscience and Law. Eagleman is best known for his publications on time perception, synesthesia, and neuroscience law. Book Summary Incognito can be divided into two main parts. The first half of the novel focuses on the workings of our unconscious brain. One of the most important points that Eagleman emphasizes throughout the entire novel is that the majority of our thoughts and behaviors are the result of unconscious processes that are either inaccessible to our conscious mind or function more efficiently when our conscious mind does not interfere. These unconscious processes are largely the result of evolution, learned experiences, genetics, and the influences of our environment. Our unconscious mind also plays a huge role in our perception of reality. Our perception of reality is often an illusion because we see with our brain and not our eyes. This means that we see only because our brain is able to interpret the information about the light waves detected by our eyes. Our unconscious brain modifies our perception of reality based on past experiences and often fills in missing information. The role of the conscious mind is to learn how to solve new problems. Through practice the conscious mind teaches the unconscious brain how to solve the problem so well that it rewires the brain; as a result, that solution or behavior is more efficiently produced by the unconscious mind. The conscious mind controls our unconscious subprograms by distributing control and resources and allowing communication between different areas of the brain. Our conscious mind is active when the something goes wrong with these subprograms or events violate our expectations. It also serves as a mediator between many of the rival teams that make up our unconscious including the left versus right hemisphere and the rational versus emotional systems. While the role of the conscious mind is an important one, its role seems small in comparison to all the behaviors our unconscious brain is responsible for. In the second half of Incognito, Eagleman explains the implications of the revelations about the unconscious that were the focus of previous chapters. The main implication according to Eagleman is that what we have learned about the unconscious brain conflicts with the way our justice system judges and sentences criminals. Currently, our legal system is based on the assumption that as humans we have free will and thus, are fully responsible for our actions. We are judged based on this assumption; unless it is proven that something impaired our mind’s control over our body while performing the criminal action. This presents a problem when we consider the way our brain works. Since, the majority of our thoughts and behaviors are the result of unconscious processes in the brain; this leaves very little room, if any, for the concept of free will. Additionally, not all brains are created equal because we cannot choose our genetics or the environment where we are raised, both of which are involved in shaping our unconscious brain. Eagleman argues that the question of free will should not matter in legal sentencing because research has shown that we are not as in control of our actions as we would like to think. He further argues the question of blameworthiness--the extent to which the criminal is to blame and the extent to which his biology is to blame--no longer makes sense either. This is because scientists now realize there is no distinction between our biology and decision-making. Additionally, as technology improves and we become better able to detect how behavior is caused by the microscopic details of our brain, more and more lawyers and criminals will appeal to the defense of biological mitigators, and more criminals will be judged not blameworthy. Consequently, the defense that the criminal’s actions were due to biological processes over which the criminal had no control is no longer valid. It is safe to assume that all criminals have something anomalous about their brain even though our current technology is not always sophisticated enough to detect anything. The solution Eagleman proposes is not to stop punishing criminals, but to change the way we punish them. He supports personalized sentences based on the likelihood of re-offense with those more likely of re-offense serving longer sentences. He further argues more emphasis should be on rehabilitation. Eagleman explains a new rehabilitation strategy called the prefrontal workout. The goal is to improve impulse control and through practice strengthen the neural circuits involved in long-term decision-making. Eagleman states that criminals should only be punished when their behavior is capable of being changed, or modified. If their behavior is not capable of being changed, then they should not be punished, but instead be taken into the care of the government. Overall, Eagleman suggests a legal system based our knowledge of the neural system that focuses on rehabilitation rather than punishment. Eagleman concludes by stating that while the revelation that our conscious mind is not at the center of who we are may seem like a dethronement of ourselves, this is not a something to be viewed negatively. Dethronement opens up the possibility of new discoveries, a better understanding of mankind and ourselves as individuals, as well as improved social policy. Evaluation I would strongly recommend Incognito to anyone who is interested in neuroscience, both novices and experts. While I have only started studying neuroscience this year, I was familiar with a fair amount of the topics discussed in Incognito such as how easily our perception can be tricked. At the same time, I learned about a great deal of interesting things that were new to me. For example, I had no idea about the extent to which our brains will go to provide a coherent narrative or seek patterns and explanations where none exist. The information presented is strongly grounded in massive amounts of neuroscience research that when synthesized provide an excellent overview of numerous aspects and views regarding the unconscious. It contains a great wealth of useful, innovative, and surprising information that is creatively presented in an easy to understand manner while still retaining its accuracy and thought provoking quality. Eagleman achieves this difficult feat of balancing simplicity with validity by using a variety of unique comparisons to our everyday world. Most importantly his style of writing is interactive and actively engages the reader by providing quick easy ways for the reader to experience firsthand what he is discussing while simultaneously demonstrating the truth of his claims. Eagleman proposes alterations to our legal system that are more compatible with our new understanding of the unconscious. While I agree with Eagleman’s proposed shift of focus from punishment to rehabilitation, he fails to fully explain the specifics regarding how we would actually go about implementing these changes. For example, while Eagleman makes it clear that free will and blameworthiness should not matter, he is not clear whether anything other than evidence and the jury’s determination of whether the accused committed the act should matter. Nor, does Eagleman clearly explain how we should or even could go about gaining popular approval from the people of America. He simply acknowledges that while it will be hard to make the shift from retribution to rehabilitation, that as a society we have been capable of changing social policy based on better understanding in the past. He compares his proposed to changes to the passing of the Civil Rights Act of 1968. This comparison belittles the struggle and hard won victory of the African American people, while inflating the severity of the perceived problem with the setup of the legal system. I believe this is one of the poorest comparisons he could have made and it is most definitely the worst comparison in the entire book. Additionally, the practicality of Eagleman’s proposed prefrontal workout is limited. First, the prefrontal workout is still in the early stages of research. It is not known how effective it is on improving impulse control or if it is effective for a wide range of people. Second, the technology required for the prefrontal workout is very expensive because it requires the use of real time feedback brain imaging. Many prisons will not be able to afford to buy such expensive brain imaging machines with their budgets. Also, this rehabilitation strategy would require prisons to be able to hire personnel who are trained to use brain imaging as well as properly lead the rehabilitation. The prefrontal workout as rehabilitation for criminal is not practical and would probably be better suited to the setting of a behavior health hospital. There is a significant disconnect between Eagleman’s fascinating, humorous, and well explained exploration of the functions of the unconscious mind in the first half of Incognito and his well-meaning, but poorly proposed alterations to the legal system. In spite of Eagleman’s failure to explain how we would go about implementing his proposed alterations to the justice system, he does thoroughly explain and support his reasons for believing such changes are necessary. Overall, the first part of the book which explored the role of the unconscious mind was better explained, supported, and just more enjoyable in general than Eagleman’s proposal to make the legal system more compatible with neuroscience. Even with Eagleman’s inadequate proposal in mind, I still urge anyone interested in neuroscience or psychology to read Incognito: The Secret Lives of the Brain. The brilliance of the first half of the book far outweighs the shortcomings of the second half. Incognito is the perfect balance of wit and intellect. You will be shocked and amazed when you learn how much your unconscious brain does without your knowledge. Conclusion I strongly believe even those who consider themselves experts in neuroscience will learn a thing or two from Incognito, especially since it talks about some of the most current research being done. Furthermore, the range of topics covered is so vast that it is hard to imagine anyone could already know everything mentioned. But, even if there is someone who knows it all, I still recommend reading Incognito: The Secret Lives of the Brain because David Eagleman relates neuroscience to some of very strange and humorous questions. After all who doesn’t want to know: How is it possible to get mad at yourself? Or why Topsy the elephant was electrocuted by Tomas Edison in 1916?
Review: I now think my brain is smarter than me - Introduction Incognito, The Secret Lives of the Brain by David Eagleman, a neuroscientist at Baylor College of Medicine, explores the hidden aspects of the brain. The premise of the book is that the conscious mind is the tip of the iceberg, and that the unconscious brain is an incredible complex and multilayered organ responsible for the vast majority of our actions, outside our willful control. By analyzing the various methods our unconscious brain dictates and influences our behavior, Eagleman seeks to introduce the reader to the vast world of cognitive neuroscience and psychology. Although there are many aspects of the brain that are not fully understood, Eagleman presents his ideas clearly along with research and observations from other scientists. Style and Structure Overall, Incognito was an interesting read. The style of the book is that each chapter explores a facet of the unconscious brain, from our senses to what your name might do with your personality to how our brain adapts automatically to new situations. Eagleman explains concepts using simple to understand comparisons and bases his ideas in real world incidents. For example, Eagleman discusses the idea of the brain consisting of rival components. He used Mel Gibson's drunken anti-Semetic controversy throughout Chapter 5, which I talk about later in this review, as an example of whether there are separate yet connected parts of our mind that rival the personality that we normally show to the world. However, I felt at some parts that there were too many anecdotes in a chapter and I felt disconnected from the overall concept. This book is written like a collection of short stories, and is very slim on technical jargon so the reader will not feel too encumbered or lost. Chapter 2 "The Testimony of the Senses: What Is Experience Really Like?" "Your brain is in the dark, but your mind constructs light." In essence, this is the purpose of all our sensory systems. Eagleman discusses such concepts like vision, perception, and illusion in order to describe the way our brain transforms the electrical signals from our receptor cells into a vivid environment. Eagleman begins the chapter by investigating the difference between seeing and vision. What you see is not decided by your eyes, but you see with your brain instead. He also talks about active vision, where your brain actively seeks to extract information from the world. The concept of active sensing also can apply to the other senses, as well as time. As a result, people who were blind can still perceive the world through the other senses, such as touch or sound. I liked the example of Bach y Rita's experiments and about Mike's experiences with regaining his lost sight. Chapter 3 "Mind: The Gap" In this chapter, Eagleman discusses the role of implicit memory in affecting our actions. An example that I found to be very relatable was when he explained how the brain initially devoted many resources to learn a new activity, but after repeating the activity, the brain devoted little energy to it. The brain developed new machinery in order to efficiently complete the task. He used a new video game as an example. At first, you concentrate very hard in order to learn the controls. However, after you know the ropes, your brain does not devote as much energy to that particular task. This ultimately shows the adaptability and plasticity of the brain. Chapter 5 "The Brain Is a Team of Rivals" The central concept of this chapter is how your brain is in conflict with itself. Eagleman suggests that the brain is always debating with itself in determining the decisions and actions that you take. There can be several factions with different opinions that must work together to reach a solution, so called a "team of rivals". One analogy that Eagleman used was the jury from 12 Angry Men. He discusses the idea of multiple opposing systems in the context of desire, morality, and emotions vs. rationality. In addition to generating conflict, the "team of rivals" exists to help reach a more robust and flexible solution to problems. For example, people who have challenged their brain through old age are able to stave off the symptoms of Alzheimer's disease due to their brain forming many alternate neural pathways that are required to solve complex problems. The lack of a clear and simple solution to puzzles and similar games forces the brain to argue with itself, increasing the flexibility and strength of the brain; this whole idea is called cognitive reserve. The primary lesson from this chapter is that the brain is a collection of systems that work together to drive our actions, as well as cause us to think that we are in control of most of what we do. In fact, the brain functions mostly free from our conscious input, but in the end, our conscious mind is what ultimately prevails. I thought this chapter was the best in the book. Overall Opinion and Recommendations In conclusion, Incognito reveals the depths and diversity of our brain. After reading it, I felt awed by how vast the role of the unconscious brain is. Despite what we presently know, there are still many things that are unknown. In the scope of things, the three pound wrinkled gooey organ is the culmination of us as a species, and for every new connection we make, a thousand more mysteries reveal themselves. The quote at the beginning of Incognito, "Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed" from Blaise Pascal, aptly describes the current state of humans. For people who are not studying neuroscience, this is an excellent book to gain a basic understanding of how the brain works. For students or scientists who have had previous experience with neuroscience topics, this book can serve as an excellent refresher. Unfortunately, for those looking for a difficult or more detailed discussion, this book may be simplistic. Nevertheless, I enjoyed the way Eagleman explained complicated ideas so the average person can understand.

### ⭐⭐⭐⭐ Inside Incognito
*by A***S on December 5, 2012*

Why do patients on Parkinson's medications become compulsive gamblers? Is a question asked in the book referring to Parkinson's. Tiny changes in the brain can cause changes in behavior, ranging from slight difference to more drastic change. In this book Eagleman talks about Parkinson's, which is a neurodegenerative brain disorder, which can progress slowly. One million people have been diagnosed with Parkinson's disease in addition to the 50 to 60 thousand diagnosed every year. Parkinson's disease is the number 14th cause of death in the United States. It has been known that some Parkinson's patients, who are taking the drug Pramipexote, turn into gamblers. Pramipexole is a drug that replenishes the Dopamine levels in the brain that have been lost because of the disease. Since Dopamine serves as a messenger in the reward system, the imbalances of Dopamine can trigger things such as: gambling, overeating, and or drug addiction. Incognito is a book that a neuroscientist named David Eagleman wrote, he explains the depths of the subconscious brain. He identifies questions that normal people, such as me, always asked myself. David refers to our brain as the mission control center. He explains what the brain is composed of and how it works. Further within the book he explains parts of the brain as well as what it does and how it works. He also explains situations and questions people may have asked at least once in their life. In chapter one David begins by stating what the brain is made of. The brain, as stated in the book, weighs about three pounds and is extremely complex. The brain is thought to be the most complex thing that could have been discovered. The brain is built of cells that we call neurons, which we have just studied in class. Each cell sends pluses to other cells. There are so many neurons in the brain that one neuron can connect to about ten thousand other neurons. David makes a connection between the complexity of the brain and our knowledge of it. It can be so complex to the point where it may seem forging to us, yet our brain makes us. David introduces a physicist and philosopher named Ernst Mach from the late 1800s. Ernst basically put strips side by side in order by shades. The strips range from black to gray to white and the shades in-between. This connects to seeing colors differently in different shades of light. He gives examples such as where two walls meet, near and away from the light, also in the corners of walls. David also further explains the difference between our brains and our minds. He gives examples of things we do every day to help understand this difference. We do things we aren't consciously aware of because it's like our brain automatically does it. To be able to remember certain things we do every day is actually called procedural memory. Procedural memory is a type of memory that is implicit, and implicit memory means that our brain has the knowledge that our mind can't access. Our brains are wired differently, but for the most part our brains are typically made or create to express proper and appropriate behavior. Humans are attracted to humans and other animals to their kind. For that same reason, healthy, food is our stomachs attractions because the vitamins and other minerals in the food are needed by our body to survive. Attractions are like a survival method, human's help each other survive as well as food help our body survive. Visual illusions have seemed to show deeper aspects which conclude of our thoughts are generated by our brain, as David stated. Brains change their outcomes when someone has suffered something like: a stroke, tumors, drugs, etc. several things can alter the way some behave and the way we rationalize things. Substances and trauma alter our brains function and our minds. I think this book is an easy read and flows well. Most of the book went hand and hand with my Neuroscience class. It made it a bit easier to understand the topics. This book breaks things down for us and explains it using examples and quotes from other psychologist, theologians, philosophers, in addition to physicist. I recommend this book because it's interesting to know how our brains and minds work on a daily bases. It helps understand why we do think and why we sometimes do them differently. This book was written for young adults. It breaks down Neuroscience into something that makes it less difficult to understand. It's written in a way that it doesn't make it misleading or less than what is true. I believe this book is true for the simple fact that it was like repeating my Neuroscience class in the pal of my hands. I liked how examples were provided as well as important quotes. This makes it much realistic because it isn't just one person's opinion. I think it's a good read for people who are interested in Neuroscience or are taking a Neuroscience class. I think I will be helpful as much if not more as it was for me. This book is up to date with the science we know today. Although it is updated it does refer to the past and history of science. I didn't think I would have been interested in this book but I really was. The examples and the referring to the past made it much more interesting for me. ut gave me somewhat of a visual and connection to what I had heard of in the past. In conclusion, I enjoyed this book and Eagleman's thoughts and theories'. Reading this book helps form your own theories and opinions on Neuroscience. It provides a clearer vision into Neuroscience.
