Adult subcortex processes numbers with the same skill as infants

(Carnegie Mellon University) Despite major brain differences, many species from spiders to humans can recognize and differentiate relative quantities. Adult primates, however, are the only ones with a sophisticated cortical brain system, meaning that the others rely on a subcortex or its evolutionary equivalent.Carnegie Mellon University scientists found that the adult subcortex processes numbers at the same level as infants and perhaps other lower-order species, such as guppies and spiders.
