[HTML][HTML] Earliest accumulation of β-amyloid occurs within the default-mode network and concurrently affects brain connectivity
It is not known exactly where amyloid-β (Aβ) fibrils begin to accumulate in individuals with
Alzheimer's disease (AD). Recently, we showed that abnormal levels of Aβ42 in …
