The relation between the acuity of approximate number system and the dorsal and ventral stream functions

Abstract

The aim of this study is to investigate whether the acuity in the Approximate Number System (ANS) is related to dorsal and ventral visual functions. Children and adults can approximate number of objects and perform approximate arithmetic operations via a non-symbolic, prelinguistic system called the Approximate Number System (ANS). Studies using neuroimaging techniques showed the role of the parietal cortex in decoding nonsymbolic quantity. Although it has been demonstrated that the parietal regions are involved also in visual processing such as coherence motion perception, little is known about the relationship between visual processes and the ANS.
