Image: Structural connectomes (top two rows) and corresponding florbetapir PET images (bottom two rows) in four patients with normal cognition (NC) with the lowest whole cortex amyloid burden (left) and the four patients with AD with the highest whole cortex amyloid burden (right) focused on the composite regions used in connectome versus amyloid analysis. Nodes represent the centroids of the FreeSurfer parcellations in the frontal (red), cingulate (green), temporal (light blue), and parietal (dark blue) regions. This is only a schematic intended to show the concepts and is not intended to show any visually discernible generalizable difference between the patients with NC and those with AD. Structural network metrics provide more sensitive information about the connectome than are apparent through visualization alone (Photo courtesy of RSNA).

fMRI Research Locates “Lost” Languages in the Brain

A baby’s mother tongue creates neural patterns that the unconscious fetal brain recollects years later, even if the child completely stops using the language, as can occur in the isntance of international adoption, according to a new joint study. The study offers the first neural evidence that traces of the “lost” language remain in the brain.  More...
