A striking way in which humans differ from non-human primates is in their ability to represent numerical quantity using abstract symbols and to use these 'mental tools' to perform skills such as exact calculations. How do functional brain circuits for the symbolic representation of numerical magnitude emerge? Do neural representations of numerical magnitude change as a function of development and the learning of mental arithmetic? Current theories suggest that cultural number symbols acquire… 

Numerical Representation in the Parietal Lobes :

  • Biology, Psychology

It is argued that numerical representation is primarily non-abstract and is supported by different neuronal populations residing in the parietal cortex and also to the field of cognitive neuroscience in general.

Specialization in the Human Brain: The Case of Numbers

Using dynamic causal modeling as a tool to disentangle neuronal specialization across regions that are commonly activated, it is found that the connectivity between the left and right intraparietal sulci is format-dependent, supporting the idea that numerical representation is subserved by multiple mechanisms within the same parietal regions.

Neural connectivity patterns underlying symbolic number processing indicate mathematical achievement in children.

Effective connectivity underlying symbolic number processing may be critical as children master the associations between numerical symbols and magnitudes, and that these connectivity patterns may serve as an important indicator of mathematical achievement.

Numerical representation in the parietal lobes: abstract or not abstract?

It is argued that numerical representation is primarily non-abstract and is supported by different neuronal populations residing in the parietal cortex and also to the field of cognitive neuroscience in general.

Different Brains Process Numbers Differently: Structural Bases of Individual Differences in Spatial and Nonspatial Number Representations

It is shown that individuals' relative use of spatial and nonspatial representations has a cerebral counterpart in the structural organization of the posterior parietal cortex, suggesting that numerical cognition relies on multiple mental representations of analogue magnitude using different neural implementations that are linked to individual traits.

Semantic and Perceptual Processing of Number Symbols: Evidence from a Cross-linguistic fMRI Adaptation Study

This work uses an fMRI adaptation paradigm to examine the neural response to Hindu-Arabic numerals and Chinese numerical ideographs in a group of Chinese readers who could read both symbol types and a control group who can read only the numerals.

The Lateralization Effect of Numerical Representation

A cultural recycling hypothesis, which focused on the modulation of culture to human brain, may shed light on the evolution of the lateralization effect of numerical representation, and further implied the survival signifi- cance of numerical cognition.

Representation of Number in Animals and Humans: A Neural Model

This article addresses the representation of numerical information conveyed by nonsymbolic and symbolic stimuli and presents a concrete proposal on the linkage between higher order numerical cognition and more primitive numerical abilities and generates specific predictions on the neural substrate of number processing.

Neural representations of numerical information can engage extensive cerebral networks, but the posterior parietal cortex and the prefrontal cortex are the key structures in primates.

Interactions between number and space in parietal cortex

It is proposed that these numerical–spatial interactions arise from common parietal circuits for attention to external space and internal representations of numbers.

Neural correlates of symbolic number processing in children and adults

It is concluded that the functional neuroanatomy underlying symbolic numerical magnitude processing undergoes an ontogenetic shift towards greater parietal engagement, which may reflect maturation of underlying representations and increasing automaticity in mapping between numerical symbols and the magnitudes they represent.

Functional Imaging of Numerical Processing in Adults and 4-y-Old Children

These results support previous claims that there is a neurophysiological link between non-symbolic and symbolic numerical processing in adulthood and are the first evidence that the neural locus of adult numerical cognition takes form early in development, prior to sophisticated symbolic numerical experience.
