Indigenous sign-systems, such as pictographs, petroglyphs, hieroglyphs, and khipu, are usually understood as relics from an inaccessible past. That is far from the truth, however, as Edgar Garcia makes clear in Signs of the Americas. Rather than being dead languages, these sign-systems have always been living, evolving signifiers, responsive to their circumstances and able to continuously redefine themselves and the nature of the world. Garcia tells the story of the present life of these sign-systems, examining the contemporary impact they have had on poetry, prose, visual art, legal philosophy, political activism, and environmental thinking. In doing so, he brings together a wide range of indigenous and non-indigenous authors and artists of the Americas, from Aztec priests and Amazonian shamans to Simon Ortiz, Gerald Vizenor, Jaime de Angulo, Charles Olson, Cy Twombly, Gloria Anzald a, William Burroughs, Louise Erdrich, Cecilia Vicu a, and many others. From these sources, Garcia depicts the culture of a modern, interconnected hemisphere, revealing that while these "signs of the Americas" have suffered expropriation, misuse, and mistranslation, they have also created their own systems of knowing and being. These indigenous systems help us to rethink categories of race, gender, nationalism, and history. Producing a new way of thinking about our interconnected hemisphere, this ambitious, energizing book redefines what constitutes a "world" in world literature.

Waking and the Reticular Activating System in Health and Disease provides a comprehensive overview on the "activating" properties of the RAS. In health, the RAS provides the basis against which we assess the external world, and in disease it distorts that world and shatters our self-image. This book describes the physiology of each process, how it is disturbed in each disorder, and what the most appropriate treatment should be.

Dr. Garcia-Rill discusses the understanding of the RAS as a system not only modulating waking, but also in charge of survival mechanisms such as fight vs flight responses and reflexes. The full spectrum of these functions helps explain the complexity of symptoms evident in such disorders as disparate as schizophrenia and Parkinson s disease. The purpose is to develop an understanding of this homeostatic mechanism that has synergistic action with other mechanisms such as appetite. The author addresses the mechanisms that control waking and arousal, and especially how those mechanisms malfunction in certain neurological and psychiatric disorders.

Nine short essays exploring the K'iche' Maya story of creation, the Popol Vuh. Written during the lockdown in Chicago in the depths of the COVID-19 pandemic, these essays consider the Popol Vuh as a work that was also written during a time of feverish social, political, and epidemiological crisis as Spanish missionaries and colonial military deepened their conquest of indigenous peoples and cultures in Mesoamerica. What separates the Popol Vuh from many other creation texts is the disposition of the gods engaged in creation. Whereas the book of Genesis is declarative in telling the story of the world's creation, the Popol Vuh is interrogative and analytical: the gods, for example, question whether people actually need to be created, given the many perfect animals they have already placed on earth. Emergency uses the historical emergency of the Popol Vuh to frame the ongoing emergencies of colonialism that have surfaced all too clearly in the global health crisis of COVID-19. In doing so, these essays reveal how the authors of the Popol Vuh-while implicated in deep social crisis-nonetheless insisted on transforming emergency into scenes of social, political, and intellectual emergence, translating crisis into creativity and world creation.

Arousal in Neurological and Psychiatric Diseases focuses on the dysregulation of arousal found in many neurological and psychiatric disorders. Chapters describe the physiology of each process, how it presents in each disorder, and the most appropriate treatment(s). The book also imparts the understanding of the RAS as a system that not only modulates waking, but also survival mechanisms, such as fight vs. flight responses and other reflexes. This book helps neuroscientists, sleep researchers, neurologists and psychiatrists understand the basic mechanisms that modulate arousal in health and disease. In addition, it promotes therapies that can alter the severity and manifestation of multiple disorders.
