In this EBook, we highlight how newly emerging techniques for non-invasive manipulation of the human brain, combined with simultaneous recordings of neural activity, contribute to the understanding of brain functions and neural dynamics in humans. A growing body of evidence indicates that the neural dynamics (e.g., oscillations, synchrony) are important in mediating information processing and networking for various functions in the human brain. Most of previous studies on human brain dynamics, however, show correlative relationships between brain functions and patterns of neural dynamics measured by imaging methods such as electroencephalography (EEG), magnetoencephalography (MEG), near-infr...
Despite increased knowledge, and more sophisticated experimental and modeling approaches, fundamental questions remain about how electricity can interact with ongoing brain function in information processing or as a medical intervention. Specifically, what biophysical and network mechanisms allow for weak electric fields to strongly influence neuronal activity and function? How can strong and weak fields induce meaningful changes in CNS function? How do abnormal endogenous electric fields contribute to pathophysiology? Topics included in the review range from the role of field effects in cortical oscillations, transcranial electrical stimulation, deep brain stimulation, modeling of field effects, and the role of field effects in neurological diseases such as epilepsy, hemifacial spasm, trigeminal neuralgia, and multiple sclerosis.
Parkinson’s Disease and Nonmotor Dysfunction fills a major gap in the current rapidly growing body of knowledge concerning Parkinson’s disease. Drs. Pfeiffer and Bodis-Wollner have correctly perceived that many nonmotor features of Parkinson’s disease are given insufficient attention in the medical literature. Unfortunately, they are often also given insufficient attention by the practicing neurologists who see these patients. As recently pointed out, there is clearly much more to Parkinson’s disease than depletion of the nigrostriatal dopamine system (1). Parkinson’s disease (not just m- tiple system atrophy) is a multisystem disorder, both pathologically and in its clinical manif...
In the modern era each new innovation poses its own special ethical dilemma. How can human society adapt to these new forms of expression, commerce, government, citizenship, and learning while holding onto its ethical and moral principles? The Changing Scope of Technoethics in Contemporary Society is a critical scholarly resource that examines the existing intellectual platform within the field of technoethics. Featuring coverage on a broad range of topics such as ethical perspectives on internet safety, technoscience, and ethical hacking communication, this book is geared towards academicians, researchers, and students seeking current research on domains of technoethics.
The concept of soldier enhancement often invokes images of dystopian futures populated with dehumanized military personnel. These futures serve as warnings in science fiction works, and yet the enhancement of soldiers' combat capability is almost as old as war itself. Today, soldier enhancement is the purpose of military training and the application of innovative technologies, but when does it begin to challenge individuals' very humanity? Bringing together the work of a diverse group of practitioners and academics, Transhumanizing War examines performance enhancement in the military from a wide range of perspectives. The book builds on two key premises: that rapid advances in science and te...
Migraine is a painful neurological condition, of which the most common symptom is an intense and disabling episodic headache. Migraine headaches are usually characterised by severe pain on one or both sides of the head. Absent serious head injuries, stroke, and tumours, the recurring severity of the pain indicates a vascular headache rather than a tension headache. Migraines are often accompanied by photophobia (hypersensitivity to light), phonophobia (hypersensitivity to sound) and nausea. Migraine is three times more common in women than in men. Some individuals can predict the onset of a migraine because it is preceded by an 'aura', visual disturbances that appear as flashing lights, zig-zag lines or a temporary loss of vision. People with migraine tend to have recurring attacks triggered by a lack of food or sleep, exposure to light, or hormonal irregularities (only in women). Anxiety, stress, or relaxation after stress can also be triggers. For many years, scientists believed that migraines were linked to
