Book Description
This book is concerned with the extent to which childhood stress and trauma lead in relative maturity to major depression (MDD) and post-traumatic stress disorder (PTSD). The loss of synapses in the cortex, accompanying childhood maltreatment, is identified as a principal mechanism for developing these disorders. Considerable attention is given to identifying interventions that will restore lost synapses, so ameliorating these mental illnesses. The book describes the emergence of abnormal psychology in youth and adult life following childhood maltreatment. Of considerable immediate concern is the extent to which such maltreatment significantly enhances the tendency to suicide and suicidality. Next, consideration is given as to how personality disorders, such as obsessive-compulsive disorder, the very dangerous borderline personality disorder, and the publicly offensive narcissistic personality disorder, arise from childhood maltreatment. The classification or nosology of mental and personality disorders as well as the principal psychoanalytic approaches available for their treatment are sketched together with recent attempts to use novel constructs that bridge between symptoms (based on patients' behavior and self-descriptions). Recently, new techniques have been developed for brain imaging and non-invasive and localized brain stimulation. These show that nodes of the distributed brain network whose malfunction is closely related to major depressive disorders are likely to differ in their importance from patient to patient. Wonderfully, so-called 'closed-loop' stimulation techniques are now available for automatically adjusting the activity of individual nodes in individual patients, relieving them of their major depression. The results of our research, and that of others using magnetic resonance imaging of mature patients that have been maltreated as children, have been to identify the nodes that have lost gray matter. We have shown that this is likely due to the loss of synapses in these nodes. Finally, the central question of how synapses may be restored in these nodes to ameliorate major depressive disorders, post-traumatic stress disorder, and suicidality is considered, emphasizing the recent revolutionary discovery that the psychedelic ketamine restores synapses and has a therapeutic effect on mental health.

Book Description
How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

Book Description
This book presents the latest state of knowledge on grey matter changes in the brain following stress and trauma. Where do these changes take place and what are the underlying molecular mechanisms? These questions are addressed in several sections, providing detailed insights into the cellular and molecular alterations that occur in the brain after stress and trauma. The changes to the grey matter in certain areas of the brain are similar in stressed humans and animals, with the most likely basis for these changes being the degeneration of synaptic connections. In the book’s first sections the reader will learn about the core network of synaptic connections that are affected by stress and trauma disorders. These synaptic connections are modulated by dopamine, serotonin and Brain Derived Neurotrophic Factor (BDNF). In subsequent chapters, the NMDA-receptor mediated plasticity of these synapses is discussed, with particular attention given to how glucocorticoids can interfere with the function of BDNF and thereby affect the synapse’s physical stability. Furthermore, the reader will learn about the importance of the genetics of the glucocorticoid gene and the epigenetic control of BDNF in connection with synaptic plasticity. The authors conclude by integrating the observations summarized in the previous sections so as to present plausible hypotheses regarding the identity of the networks, synapses and molecular pathways that support fear and extinction. Providing an up-to-date overview of the mechanisms of synaptic plasticity and physiological changes in the stressed and traumatized brain, this book will appeal to researchers, clinicians and students in the neurosciences.

Book Description
This volume presents a comprehensive overview of childhood trauma, considering the psychopathological definition and its neurobiological implications as well as its impact on different psychiatric disorders. The focus on childhood trauma rather than that occurring in adulthood is important due to its general “neuro-psyco-socio” and its specific biological implications, since trauma during childhood impacts directly on neurodevelopment. It has been suggested that early life stress increases vulnerability to psychiatric disorders; however, the exact mechanisms of this association are not yet completely understood. Although childhood trauma could be considered too unspecific to be an important risk factor for individual psychiatric disorders since it seems to occur across the board, it impacts differently on different psychiatric disorders, and it can modulate their clinical expression. Therefore, the assessment of early trauma needs to be included in the clinical evaluation of patients with psychiatric disorders. The volume will be an invaluable tool for psychiatrists, helping them to select suitable pharmacological, psychotherapeutic and rehabilitative treatments.

Book Description
The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Book Description
The instant New York Times bestseller “Excellent…Outstanding for its breadth of research, the liveliness of the writing, and the depth of humanity it conveys.” – Wall Street Journal One of our great behavioral scientists, the bestselling author of Behave, plumbs the depths of the science and philosophy of decision-making to mount a devastating case against free will, an argument with profound consequences Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do. Determined offers a marvelous synthesis of what we know about how consciousness works—the tight weave between reason and emotion and between stimulus and response in the moment and over a life. One by one, Sapolsky tackles all the major arguments for free will and takes them out, cutting a path through the thickets of chaos and complexity science and quantum physics, as well as touching ground on some of the wilder shores of philosophy. He shows us that the history of medicine is in no small part the history of learning that fewer and fewer things are somebody’s “fault”; for example, for centuries we thought seizures were a sign of demonic possession. Yet, as he acknowledges, it’s very hard, and at times impossible, to uncouple from our zeal to judge others and to judge ourselves. Sapolsky applies the new understanding of life beyond free will to some of our most essential questions around punishment, morality, and living well together. By the end, Sapolsky argues that while living our daily lives recognizing that we have no free will is going to be monumentally difficult, doing so is not going to result in anarchy, pointlessness, and existential malaise. Instead, it will make for a much more humane world.
