Attentional amplification of neural codes for number independent of other quantities along the dorsal visual stream
- Biology, PsychologybioRxiv
- 2019
A dedicated extraction mechanism for numerosity that operates independently of other quantitative dimensions of the stimuli is revealed, and it is suggested that later stages along the dorsal stream are most important for the explicit manipulation of numerical quantity.

Symbols Are Special: An fMRI Adaptation Study of Symbolic, Nonsymbolic, and Non-Numerical Magnitude Processing in the Human Brain
- Psychology, BiologyCerebral cortex communications
- 2021
These findings challenge the longstanding notion that the culturally acquired ability to conceptualize symbolic numbers is represented using entirely the same brain systems that support the evolutionarily ancient system used to process quantities.
Neural basis of approximate number system develops independent of visual experience
- PsychologybioRxiv
- 2019
It is found that sequences of 4, 8, 16 and 32 tones each elicited unique patterns of fMRI activity in the IPS of both sighted and congenitally blind individuals, such that the quantity a participant heard on a given trial could be reliably predicted based on the pattern of observed IPS activity.
Mapping numerical perception and operations in relation to functional and anatomical landmarks of human parietal cortex
- BiologybioRxiv
- 2019
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.

Numerosity representation is encoded in human subcortex
- Biology, PsychologyProceedings of the National Academy of Sciences
- 2017
This series of experiments demonstrates a role of the subcortex in discriminating numerosities in larger (4:1 or 3:1), but not in smaller ratios, and suggests conservation of ontogenetically and phylogenetically lower-order systems in adults’ numerical abilities.
Towards a standardization of non-symbolic numerical experiments: GeNEsIS, a flexible and user-friendly tool to generate controlled stimuli
- BiologybioRxiv
- 2021
The main aim of this tool is to provide researchers in the field of numerical cognition a manageable and precise instrument to produce visual numerical arrays controlled for all the continuous variables.

Semantic Associations between Signs and Numerical Categories in the Prefrontal Cortex
- Psychology, BiologyPLoS biology
- 2007
A cardinal role of the prefrontal cortex is suggested in establishing semantic associations between signs and abstract categories, a cognitive precursor that may ultimately give rise to symbolic thinking in linguistic humans.
Semantic and Perceptual Processing of Number Symbols: Evidence from a Cross-linguistic fMRI Adaptation Study
- Biology, PsychologyJournal of Cognitive Neuroscience
- 2013
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.
THREE PARIETAL CIRCUITS FOR NUMBER PROCESSING
- Psychology, BiologyCognitive neuropsychology
- 2003
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.
Neuronal correlates of a visual “sense of number” in primate parietal and prefrontal cortices
- Biology, PsychologyProceedings of the National Academy of Sciences
- 2013
Visual numerosity is spontaneously represented as a perceptual category in a dedicated parietofrontal network, which may form the biological foundation of a spontaneous number sense, allowing primates to intuitively estimate the number of visual items.
Representation of Number in Animals and Humans: A Neural Model
- Biology, PsychologyJournal of Cognitive Neuroscience
- 2004
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.
Monotonic Coding of Numerosity in Macaque Lateral Intraparietal Area
- Biology, PsychologyPLoS biology
- 2007
It is shown, for the first time, that a population of neurons in the lateral intraparietal area of monkeys encodes the total number of elements within their classical receptive fields in a graded fashion, across a wide range of numerical values.
Distinct Cerebral Pathways for Object Identity and Number in Human Infants
- Biology, PsychologyPLoS biology
- 2008
Brain-imaging evidence for distinct cerebral coding of number and object identity in 3-mo-old infants is presented, highlighting the developmental continuity of number sense by pointing to early functional biases in brain organization that may channel subsequent learning to restricted brain areas.
Neuronal population coding of continuous and discrete quantity in the primate posterior parietal cortex
- BiologyProceedings of the National Academy of Sciences
- 2007
It is shown that length and numerosity are encoded by functionally overlapping groups of parietal neurons, and different information-carrying processes of partly intermingled neuronal networks in the parietal lobe seem to encode various forms of abstract quantity.
Supramodal numerosity selectivity of neurons in primate prefrontal and posterior parietal cortices
- Psychology, BiologyProceedings of the National Academy of Sciences
- 2012
The finding of neurons responding to numerosity irrespective of the sensory modality supports the idea of a nonverbal, supramodal neuronal code of numerical quantity in the primate brain.
Specialization in the Human Brain: The Case of Numbers
- Biology, PsychologyFront. Hum. Neurosci.
- 2011
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.
