Humans share with nonhuman animals a quantification system for representing the number of items as nonverbal mental magnitudes. Over the past decade, the anatomical substrates and neuronal mechanisms of this quantification system have been unraveled down to the level of single neurons. Work with behaviorally trained nonhuman primates identified a parieto-frontal cortical network with individual neurons selectively tuned to the number of items. Such ‘number neurons’ can track items across space… 

Neuronal correlates of a visual “sense of number” in primate parietal and prefrontal cortices

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.

Studying number neurons provides insights into how information is maintained in working memory and transformed in tasks that require rule-based decisions and provides a window into the neuronal mechanisms of high-level brain functions.

Single-cell coding of sensory, spatial and numerical magnitudes in primate prefrontal, premotor and cingulate motor cortices

It was found that almost exclusively PFC neurons represented the different magnitude types during sample presentation and working memory periods, and Neuronal magnitude discriminability, coding strength and temporal evolution were comparable between magnitude types encoded by PFC neuron populations.

Neurons selective to the number of visual items in the corvid songbird endbrain

Comparison of both behavioral and neuronal representations of numerosity revealed that the data are best described by a logarithmically compressed scaling of numerical information, as postulated by the Weber–Fechner law.

Sensory and Working Memory Representations of Small and Large Numerosities in the Crow Endbrain

A neuronal code for sensory representation and working memory of numerosities in the crow NCL exhibiting several characteristics that are surprisingly similar to the ones found in primates is reported.

Stable numerosity representations irrespective of magnitude context in macaque prefrontal cortex

The data suggest that numerosity detectors in the PFC do not adapt their response properties to code stimuli according to changing magnitude context, and numerosity representations seem to rely on a sparse and stable ‘labeled line’ code.

Numerosity representations in crows obey the Weber–Fechner law

The detailed analysis of the performance indicates that numerosity representations in crows are scaled on a logarithmically compressed ‘number line’, which helps to resolve a classical debate in psychophysics: the mental number line seems to beLogarithmic rather than linear, and not just in primates, but across vertebrates.

Comparison of abstract decision encoding in the monkey prefrontal cortex, the presupplementary, and cingulate motor areas.

The findings highlight the role of both preSMA and CMAr in abstract cognitive processing and emphasize that both frontal areas encode decisions prior to the preparation of a motor output.

Neural basis of approximate number system develops independent of visual experience

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.



Neuronal population coding of continuous and discrete quantity in the primate posterior parietal cortex

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.

Monotonic Coding of Numerosity in Macaque Lateral Intraparietal Area

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.

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.

Tuning to non‐symbolic proportions in the human frontoparietal cortex

The identification of tuning to non‐symbolic ratio stimuli, irrespective of notation, adds to the magnitude system a remarkable level of sophistication by demonstrating automatic access to a composite, derived quantitative measure.

Contributions of primate prefrontal and posterior parietal cortices to length and numerosity representation.

Single-cell results are in good agreement with functional imaging data from humans and support the notion that representations of continuous and discrete quantities share a frontoparietal substrate, with IPS neurons constituting the putative entry stage of the processing hierarchy.

Compressed Scaling of Abstract Numerosity Representations in Adult Humans and Monkeys

A noisy nonverbal estimation system obeying Weber's Law in humans and monkeys is demonstrated and may indicate a gradual transformation of a logarithmic to linear magnitude scale in humans as the result of a cultural transformation process during the course of mathematical education.

Analog Numerical Representations in Rhesus Monkeys: Evidence for Parallel Processing

The behavioral performance of two rhesus monkeys judging the numerosities 1 to 7 during a delayed match-to-sample task shows similar discrimination performance irrespective of the exact physical appearance of the stimuli, confirming that performance was based on numerical information.

Notation-Independent Representation of Fractions in the Human Parietal Cortex

Using functional MRI adaptation, it is shown that populations of neurons in human fronto-parietal cortex are tuned to preferred fractions, generalizing across the format of presentation and demonstrating that the human brain uses the same analog magnitude code to represent both absolute and relative quantity.

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.
