Perceiving numerosity (the number of items in a collection) is a fundamental ability for all animals. However, this poses a significant theoretical challenge from a neurocomputational perspective, as it is unclear how a discrete value is encoded in the brain when neural signals are inherently continuous. From a series of psychophysical, neural, and computational modeling studies, I propose algorithmic-level mechanisms for the sensory representation of numerosity. The core of the proposal is that numerosity perception emerges as a byproduct of canonical perceptual principles such as center-surround receptive field properties, divisive normalization, and coarse-to-fine processing. According to this view, number sense does not emerge from the representation of numbers but rather from the representation of normalized local contrast. These findings call for a clear distinction between percepts and concepts of number and further investigations about the neural processes beyond the initial sensory representational stage needed to construct the conceptual content of number.<\/p>\n","protected":false},"featured_media":0,"template":"","acf":[],"_links":{"self":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event\/4881"}],"collection":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event"}],"about":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/types\/event"}],"version-history":[{"count":5,"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event\/4881\/revisions"}],"predecessor-version":[{"id":4886,"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event\/4881\/revisions\/4886"}],"wp:attachment":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/media?parent=4881"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
