1 region, 2 functions: Brain cells' multitasking key to understanding overall brain function

egory-based decision-making tasks."

What does the brain gain from this territorial arrangement?

"There has long been a tendency to look at the many distinct anatomical areas of the cerebral cortex of the brain and to assume that each area is like a specialized module that plays a very specific function." Freedman said. "Our results support the growing sense that most, if not all, of these brain areas have multiple overlapping roles."

A brain that includes such overlapping functional centers may be more efficient, Freedman suggests. "It makes mapping these regions more complicated for scientists like us, but it may boost the brain's capacity. If each area can do a number of different things, you can squeeze a lot more function into the same space."

A next step is to understand how neuronal category representations develop in LIP neurons during the learning process, the authors said.
