A study from the UCSF Department of Radiology and Biomedical Imaging investigates the relationship between aberrant neuronal circuit mechanisms and functional abnormalities observed in Alzheimer's disease (AD) using magnetoencephalography (MEG) imaging. AD is a multifaceted neurodegenerative condition that gradually erodes cognitive function, presenting significant challenges for patients and their families. Despite extensive research, there is still a lot we don't understand about its underlying mechanisms.
