  1. These findings seem consistent with how the neurons of various brain loci communicate. The parietal lobe has been found in recent studies utilizing PET-PIB scans to be a prominent figure in early effects of amyloid deposition and shows high correlation with hippocampus atrophy.

    fMRI studies further make a more significant correlation as well.
