Leighton Hinkley, PhD, first author of "Distinct neurophysiology during nonword repetition in logopenic and non-fluent variants of primary progressive aphasia" in Human Brain Mapping uses advanced imaging techniques to better understand neurodegenerative diseases. The research focused on Primary Progressive Aphasia (PPA), a condition within the Alzheimer's disease spectrum. In a recent interview Hinkley, a neuroscientist at the University of California, San Francisco (UCSF), explains his team's neuroimaging research.
