Exact and approximate judgements of visual and auditory numerosity: an fMRI studyManuela Piazza
Institute of Cognitive Neuroscience, University College London, London, UK
Brain Res 1106:177-88. 2006..Counting activates additional left prefrontal, parietal, and bilateral premotor areas, again independently from stimulus modality. These results dissociate two neuronal systems that underlie different numerosity judgements...
How humans count: numerosity and the parietal cortexManuela Piazza
Center for Mind Brain Sciences, University of Trento, Italy
Neuroscientist 15:261-73. 2009....
A magnitude code common to numerosities and number symbols in human intraparietal cortexManuela Piazza
Institut National de la Sante et de la Recherche Medicale INSERM, Cognitive Neuroimaging Unit, Service Hospitalier Frederic Joliot, F 91401 Orsay, France
Neuron 53:293-305. 2007..They support the idea that symbols acquire meaning by linking neural populations coding symbol shapes to those holding nonsymbolic representations of quantities...
Interactions between number and space in parietal cortexEdward M Hubbard
INSERM Unit 562 Cognitive Neuroimaging, Service Hospitalier Frederic Joliot, 4 Place du General Leclerc, F94101 Orsay, France
Nat Rev Neurosci 6:435-48. 2005....
Does subitizing reflect numerical estimation?Susannah K Revkin
INSERM, U562, Cognitive Neuroimaging Unit, Gif Yvette, France
Psychol Sci 19:607-14. 2008....
Neural mechanisms of attentional shifts due to irrelevant spatial and numerical cuesMariagrazia Ranzini
INSERM, U562, Cognitive Neuroimaging Unit, Gif Yvette, France
Neuropsychologia 47:2615-24. 2009....
Distributed and overlapping cerebral representations of number, size, and luminance during comparative judgmentsPhilippe Pinel
INSERM Unit 562, Service Hospitalier Frederic Joliot, CEA DRM DSV, 4 Place du General Leclerc, 91401 Orsay Cedex, France
Neuron 41:983-93. 2004....
Subitizing reflects visuo-spatial object individuation capacityManuela Piazza
Center for Mind Brain Sciences, University of Trento, Italy
Cognition 121:147-53. 2011..Here we provide first direct evidence for the alternative object indexing hypothesis, and show that subitizing reflects a domain general mechanism shared with other tasks that require multiple object individuation...
The role of attentional priority and saliency in determining capacity limits in enumeration and visual working memoryDavid Melcher
Center for Mind Brain Sciences CIMeC, University of Trento, Rovereto, Italy
PLoS ONE 6:e29296. 2011..Overall, the pattern of results suggests that our abilities to enumerate and remember small groups of stimuli are grounded in an attentional priority or salience map which represents the location of important items...
Neurocognitive start-up tools for symbolic number representationsManuela Piazza
INSERM, U562, Cognitive Neuroimaging Unit, CEA SAC DSV DRM Neurospin Center, Bât 145, Point Courier 156, F 91191 Gif sur Yvette Cedex, France
Trends Cogn Sci 14:542-51. 2010....
Verbal numerosity estimation deficit in the context of spared semantic representation of numbers: a neuropsychological study of a patient with frontal lesionsSusannah K Revkin
INSERM, U562, Cognitive Neuroimaging Unit, F 91191 Gif Yvette, France
Neuropsychologia 46:2463-75. 2008..This case study allows disentangling different processes involved in estimation and contributes to a better understanding of the cognitive estimation deficits frequently reported for patients with frontal lesions...
Single-trial classification of parallel pre-attentive and serial attentive processes using functional magnetic resonance imagingManuela Piazza
Inserm U562 NeuroImagerie Cognitive, Service Hospitalier Frederic Joliot, CEA DRM DSV, 4 Place du General Leclerc, F 91401 Orsay Cedex, France
Proc Biol Sci 270:1237-45. 2003..Beyond the subitizing/counting debate, this approach may prove useful to probe the attentional demands of other cognitive tasks...
Tuning curves for approximate numerosity in the human intraparietal sulcusManuela Piazza
, CEA/DSV, 91401 Orsay Cedex, France
Neuron 44:547-55. 2004..Anatomically, the intraparietal site coding for number in humans is compatible with that observed in macaque monkeys. Our results therefore suggest an evolutionary basis for human elementary arithmetic...
Are subitizing and counting implemented as separate or functionally overlapping processes?Manuela Piazza
Institute of Cognitive Neuroscience, London, United Kingdom
Neuroimage 15:435-46. 2002..Results speak against the idea of the two processes being implemented in separable neural systems...
