Modulation of Parietal Activation by Semantic Distance in a Number Comparison Task

  title={Modulation of Parietal Activation by Semantic Distance in a Number Comparison Task},
  author={Philippe Pinel and Stanislas Dehaene and Denis Rivi{\`e}re and D. LeBihan},
The time to compare two numbers shows additive effects of number notation and of semantic distance, suggesting that the comparison task can be decomposed into distinct stages of identification and semantic processing. Using event-related fMRI and high-density ERPs, we isolated cerebral areas where activation was influenced by input notation (verbal or Arabic notation). The bilateral extrastriate cortices and a left precentral region were more activated during verbal than during Arabic…

The neural origin of the priming distance effect: Distance‐dependent recovery of parietal activation using symbolic magnitudes
It is shown that bilateral parietal activations present a distance‐dependent recovery of activation positively correlated with the distance between primes and targets, and that the relative importance of the semantic and nonsemantic pathways in a dual‐route model of number processing is modulated by symbolic notation.
Number representation in the parietal lobes
The first experiment demonstrates that repetitive Transcranial Magnetic Stimulation (rTMS) can be used on normal subjects to replicate findings from studies of patients whose ability to calculate after brain injury was impaired and suggests that parietal cortical contribution to number magnitude representation is intimately related to its role in basic sensorimotor processes.
Distinct neural mechanisms for reading Arabic vs. verbal numbers: An ERP study
The data suggest distinct mechanisms for number reading through ciphers (digits) or words, and it can be speculated that numerosity processing would involve circuits originally involved in processing space (i.e., rAG/rIPS).
The horizontal segment of the intraparietal sulcus appears as a plausible candidate for domain specificity: It is systematically activated whenever numbers are manipulated, independently of number notation, and with increasing activation as the task puts greater emphasis on quantity processing.
Mapping numerical perception and operations in relation to functional and anatomical landmarks of human parietal cortex
The results reveal a functional heterogeneity within human intraparietal cortex where the visual field map representations in superior/medial parts ofIPS and superior parietal gyrus are involved predominantly in numerosity perception, whereas numerical operations predominantly recruit lateral/inferior parts of IPS.
The Influence of verbalization on the pattern of cortical activation during mental arithmetic
The results confirm that strong verbalizers use mental speech as a form of mental imagination more strongly than weak verbalizers and suggest that the left AG has no specific affinity to the verbal domain and subserves number processing in a modality-general way.
Neural correlates of the numerical distance effect in children
It is proposed that the left IPS would be engaged in the refinement of cognitive processes involved in number comparison during development, while the right IPS would underlie the semantic representation of numbers and its activation would be mainly affected by the numerical proximity between them.


Functional anatomy of a common semantic system for words and pictures
This study studied the functional anatomy of semantic processing by using positron-emission tomography to contrast activity during two semantic tasks (probing knowledge of associations between concepts, and knowledge of the visual attributes of these concepts), performed either with words or with pictures.
Neuroanatomical Substrates of Arabic Number Processing, Numerical Comparison, and Simple Addition: A PET Study
Comparison and simple addition fact retrieval revealed a fronto-parietal network involving mainly the left intraparietal sulcus, the superior parietal lobule and the precentral gyrus, whereas addition also activated the orbito-frontal areas and the anterior insula in the right hemisphere.
Event-related fMRI analysis of the cerebral circuit for number comparison.
The results confirm the role of the right fusiform gyrus in digit identification processes, and of the inferior parietal lobule in the internal manipulation of numerical quantities, in the serial-stage model of the number comparison task.
Distinct Cortical Areas for Names of Numbers and Body Parts Independent of Language and Input Modality
These results complement the existing neuropsychological and brain-imaging literature by suggesting that within the extensive network of bilateral parietal regions active during both number and body-part processing, a subset shows category-specific responses independent of the language and modality of presentation.
Graded Functional Activation in the Visuospatial System with the Amount of Task Demand
The data suggest that the amount of activation in the various cortical regions that support visuospatial processing is related to the amount, as well as to the type, of computational demand.

How the simultaneous recording of event-related potentials (ERPs) in the same task can provide complementary information that cannot be obtained using RTs alone is described.
Differential Contributions of the Left and Right Inferior Parietal Lobules to Number Processing
Partially distinct cerebral circuits with the dorsal parietal pathway underlie distinct arithmetic operations in brain-lesioned patients.
Neural Correlates of Simple and Complex Mental Calculation
The functional anatomy of the two basic resolution strategies involved in mental calculation, namely arithmetical fact retrieval and actual computation, is revealed, questioning in particular the respective role of language and/or visuospatial cerebral areas.
Understanding dissociations in dyscalculia: a brain imaging study of the impact of number size on the cerebral networks for exact and approximate calculation.
Two cerebral networks for number processing are revealed: Rote arithmetic operations with small numbers have a greater reliance on left-lateralized regions, presumably encoding numbers in verbal format, and Approximation and exact calculation with large numbers, however, put heavier emphasis on the left and right parietal cortices.
