Reinterpreting The Human Brain: New Mapping Reveals 100+ New Areas

Human Brain Mapped in Unprecedented Detail (+Video)

Nearly 100 previously unidentified brain areas revealed by examination of the cerebral cortex 

Linda Geddes | July 20, 2016

Think of a spinning globe and the patchwork of countries it depicts: such maps help us to understand where we are, and that nations differ from one another. Now, neuroscientists have charted an equivalent map of the brain’s outermost layer—the cerebral cortex—subdividing each hemisphere's mountain- and valley-like folds into 180 separate parcels.
Ninety-seven of these areas have never previously been described, despite showing clear differences in structure, function and connectivity from their neighbours. The new brain map is published today in Nature.

"The 97 sections (per hemisphere) that were previously not known will allow scientists to delve much deeper into the brain’s functions. The new map can help surgeons and lead to cures for diseases like Alzheimer’s and autism as well a fresh understanding of how our most important organ develops and ages. In particular, researchers from Washington University in Saint Louis found 360 sections in the cerebral cortex, the brain’s outer layer of neural tissue. With 180 sections per hemisphere, each such section coordinates a particular activity, and the sheer abundance of new cortical areas shows how much there is still to learn about the brain’s operations.] Source:
