Brain network organization, the emergence of cognition, and the accumulation of neurodegenerative pathology are interwoven concepts frequently studied under the umbrella of behavioral neurology, neuropsychiatry, neuropsychology, and neuropathology. One approach to studying the organization of cognitive processes is to study those with selective deficits in such networks. To understand how...
The brain is known to shrink in normal aging or neurodegenerative disease and yet the neurobiological underpinnings of the cortical atrophy remain elusive. The structural changes that represent cortical atrophy can be measured during life using the reliable and quantitative method known as magnetic resonance imaging (MRI). Primary progressive aphasia...
