This is a story: a story about neurobiology and aging and imaging and neurodegeneration, but most substantially it is about neuronal-circuits and networks--and how they resist the ravages of age and neuropathology. There are many ways for readers to augment their NBOA (Neurobio of Aging) knowledge, but this is a book you can read straight through and hopefully with considerable ease or at least interest. From cellular and DNA damage to neuronal pathology, from neural system dysfunction to fMRI/connectome analytics, and from clinical imaging of dementia to pharmaceutical approaches, the study of NBOA is an epic journey. This book is a good start. You can begin building a wealth of knowledge architectures in your mind.
