Neural correlates of the number–size interference task in children
Imaging baseline contrasts revealed activations in frontal, parietal, occipital and cerebellar areas bilaterally in children, different from results usually reported for adults.
The Involvement of the Inferior Parietal Cortex in the Numerical Stroop Effect and the Distance Effect in a Two-digit Number Comparison Task
The inferior parietal cortex showed common and distinct patterns of activation for both attentional selection and number comparison processes, and its activity was modulated by the Stroop-like interference effect and the distance effect.
When brightness counts: the neuronal correlate of numerical-luminance interference.
The current results support the idea that the parietal lobe might be equipped with neuronal substrates for magnitude processing even for nonspatial dimensions.
A common representation for semantic and physical properties: a cognitive-anatomical approach.
It is proposed that the processing of semantic and physical magnitude information is carried out by a shared brain structure that subserves various comparison processes by representing various quantities on an amodal magnitude scale.
Attentional amplification of neural codes for number independent of other quantities along the dorsal visual stream
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.
Interaction of Numerosity and Time in Prefrontal and Parietal Cortex
A two-stage model of numerosity–time interactions whereby the interaction at the perceptual level occurs within the parietal region and the interaction in categorical decisions takes place in the prefrontal cortex is suggested.
Larger stimuli are judged to last longer.
The idea that magnitudes in temporal and nontemporal dimensions are not independent and implies the existence of generalized and abstract components in the magnitude representations is supported.
Encoding Goals but Not Abstract Magnitude in the Primate Prefrontal Cortex


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.
Quantity determination and the distance effect with letters, numbers, and shapes: a functional MR imaging study of number processing.
Numbers and letters, which are stimuli more associated with abstract symbolism compared with shapes, resulted in slower reaction times and an increased number of active brain regions, indicating access to a mental continuum of quantity.
A Supramodal Number Representation in Human Intraparietal Cortex
The Generality of Parietal Involvement in Visual Attention
Parietal Representation of Symbolic and Nonsymbolic Magnitude
Functional brain imaging results confirm the hypothesis that quantity is represented by a common mechanism for both symbolic and nonsymbolic stimuli in IPS.
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.
Dissociating Prefrontal and Parietal Cortex Activation during Arithmetic Processing
Functional magnetic resonance imaging findings indicate a dissociation in prefrontal and parietal cortex function during arithmetic processing and provide the first evidence for a specific role for the angular gyrus in arithmetic computation independent of other processing demands.
Matching two imagined clocks: the functional anatomy of spatial analysis in the absence of visual stimulation.
This result clarifies the nature of top-down processes in the dorsal stream of the human cerebral cortex and provides evidence for a specific convergence of the pathways of imagery and visual perception within the parietal lobes.
Perceptual comparisons through the mind’s eye
Four experiments tested a theory of memory and cognition which assumes that verbal and nonverbal information are processed in functionally distinct LTM systems, and results cannot be easily explained by current verbal coding or abstract theories of LTM representations.
