Adaptation to visual numerosity changes neural numerosity selectivity [PDF]
NeuroImage, 2021 Perceiving numerosity, i.e. the set size of a group of items, is an evolutionarily preserved ability found in humans and animals. A useful method to infer the neural underpinnings of a given perceptual property is sensory adaptation.

Deprivation of Auditory Experience Influences Numerosity Discrimination, but Not Numerosity Estimation [PDF]
Brain Sciences, 2022 Number sense is the ability to estimate the number of items, and it is common to many species. Despite the numerous studies dedicated to unveiling how numerosity is processed in the human brain, to date, it is not clear whether the representation of ...

Tuned neural responses to haptic numerosity in the putamen
NeuroImage, 2021 The ability to perceive the numerosity of items in the environment is critical for behavior of species across the evolutionary tree. Though the focus of studies of numerosity perception lays on the parietal and frontal cortices, the ability to perceive ...

Stage-Specific Processing in Numerosity Working Memory: ERP Evidence for Load and Mismatch Effects in a Delayed Match-to-Sample Task [PDF]
NeuroSciNumerosity can be represented in symbolic formats and non-symbolic dot arrays. How numerosity load unfolds across WM encoding/maintenance and test-stage comparison within a single paradigm remains unclear, especially within the tested 4–6 range.

Numerosity adaptation suppresses early visual responses [PDF]
Communications BiologyHumans and many other animals possess an innate ability to rapidly perceive numerosity: the number of objects in a visual scene. Numerosity perception is influenced by adaptation, whereby previously viewed numerosities affect perception of the current ...

Number words recruit numerosity-related cortex in 3- to 5-year-old children [PDF]
Developmental Cognitive NeuroscienceLearning to map number words onto their ordinal and quantitative meanings is critical in the acquisition of formal mathematics. Previous neuroimaging work in adults suggests that the intraparietal sulcus (IPS) represents verbal, symbolic number (i.e ...

The Effects of Auditory Numerosity and Magnitude on Visual Numerosity Representation: An ERP Study [PDF]
Journal of Numerical Cognition, 2020 Numerical representation is not restricted to sensory modalities. It remains unclear how numerosity processing in different modalities interacts within the brain.

Adaptation acts directly on the sensory representation of numerosity [PDF]
Scientific ReportsLike most perceptual systems, the perception of numerosity is susceptible to adaptation. However, while adaptation to large numerosities is large and spectacular, obvious on demonstration, adapting to sparse fields (reverse adaptation) causes smaller ...

Object numerosity influence sensorimotor programs evoked by graspable object nouns [PDF]
Frontiers in PsychologyGrasping actions can be evoked and modulated by a range of linguistic and abstract concepts, including object nouns, adjectives and numbers. The present study investigated whether the grasp-compatibility effect—typically elicited by graspable object ...

Distinct neural representational geometries of numerosity in early visual and association regions across visual streams [PDF]
Communications BiologyVisual numerosity, traditionally linked to the parietal cortex, is now thought to be represented across a broader cortical network, including early visual and associative areas in both streams.
