Numerosity (the number of objects in a set), like color or movement, is a basic property of the environment. Animal and human brains have been endowed by evolution by mechanisms based on parietal circuitry for representing numerosity in an highly abstract, although approximate fashion. These mechanisms are functional at a very early age in humans and spontaneously deployed in the wild by animals of different species. The recent years have witnessed terrific advances in unveiling the neural code…

Numerosity, Abstraction, and the Emergence of Symbolic Thinking

In this paper we tentatively propose that one of the feral cognitive bases for modern symbolic thinking may be numerosity, that is, the ability to appreciate and understand numbers. We proffer that

The Language–Number Interface in the Brain: A Complex Parametric Study of Quantifiers and Quantities

A new fMRI paradigm is used in an attempt to dissociate Estimation from Comparison, and at the same time uncover the neural relation between numerosity and language, to fortify the homology of Estimation and Comparison between humans and monkeys.

Parametric Representation of Tactile Numerosity in Working Memory

A delayed match-to-numerosity paradigm to test what brain regions retain approximate numerosity memoranda found numerosity-specific WM representations in the right LPFC as well as in the supplementary motor area and the left premotor cortex extending into the superior frontal gyrus, thus bridging the gap in abstract quantity WM literature.

Newborn infants perceive abstract numbers

It is shown that newborn infants spontaneously associate stationary, visual-spatial arrays of 4–18 objects with auditory sequences of events on the basis of number, providing evidence for abstract numerical representations at the start of postnatal experience.

Distributed versus focused attention (count vs estimate).

An overview of how numerosity is represented in the visual domain and its relation to different modes of attention suggests that a focused attention mode is more suitable for enumeration, whereas a distributed attention modes is better for estimation.

Topology-defined units in numerosity perception

It is proposed that numbers or the primitive units counted in numerosity perception are influenced by topological invariants, such as connectivity and the inside/outside relationship.

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.

Symbols and quantities in parietal cortex: elements of a mathematical theory of number representation and manipulation

In this chapter, I put together the first elements of a mathematical theory relating neurobiological observations to psychological laws in the domain of numerical cognition. The starting point is the

Development of Elementary Numerical Abilities: A Neuronal Model

The computer simulations account for several phenomena in the numerical domain, including the distance effect and Fechner's law for numbers, and demonstrate that infants' numerosity detection abilities may be explained without assuming that infants can count.

Newborn infants perceive abstract numbers

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.

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.

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.
