• The abstract discusses the dual nature of number: as a perceptual property (cardinality) and a mathematical concept. It highlights the neural basis for processing numerical information in both humans and animals, focusing on the roles of the parietal cortex and occipitotemporal cortex in numerical cognition.

Purpose of the Study:

• To explore the neural underpinnings of numerical cognition.
• To differentiate the processing of numerical perception and symbolic representation.

Main Methods:

• Review of existing neuroimaging and behavioral studies.
• Analysis of primate and human cognitive abilities related to number.

Main Results:

• Approximate cardinality detection is a fundamental ability present across species.
• The posterior parietal cortex is implicated in numerical perception in primates.
• Semantic coding of numerical symbols converges in the parietal cortex.
• Shape coding of number symbols involves bilateral occipitotemporal cortex.

Conclusions:

• Number processing involves distinct but interacting neural systems.
• The brain utilizes both dedicated and overlapping regions for numerical perception and symbolic representation.
