The battle against brain attack has been joined on several fronts. This book is a record of the counterattack being waged by researchers and clinicians in Japan. Their strategies set forth here include protecting the brain from latently-progressing cerebrovascular injuries; assessing the strength of brain attacks and protecting the brain from the rapid progression of cerebrovascular disorders following the onset of stroke; and promoting recovery of brain functions after initial stroke damage with techniques of neuroregeneration. Cerebral ischemia, cerebral aneurysm and vasospasm, along with neurogenesis, infarct tolerance, hypothermia and brain-imaging technologies, are among the several areas in which scientists have contributed their expertise in this volume. The text serves to bridge basic studies and clinical applications, creating a resource for both researchers and practitioners.
