Cortical areas involved in Arabic number reading

Abstract

Our findings strongly support the fact that the acquisition through education of specific symbolic entities, such as Arabic numbers, could result in the segregation and the specialization of anatomically distinct brain areas.

Regions in the human inferior temporal gyrus are engaged in numerosity processing across visual stimulus categories

“…However, such a stimulus preference was found only in 35.30% and 11.76% of the participants in the left and right hemisphere, respectively. These results are in contrast with previous work successfully identifying ITG-numbers (Pinel et al 1999;Roux et al 2008;Cui et al 2013;Shum et al 2013;Hermes et al 2015;Amalric and Dehaene 2016;Daitch et al 2016;M. Grotheer et al 2016;Mareike Grotheer et al 2016).…”

Neural activation patterns and connectivity in visual attention during number and non-number processing: An ERP study using Ishihara pseudoisochromatic plates

“…However, in the current study, the right inferior temporal cortex activation during number plate tasks was consistent with findings reported by others [78,79]. Additionally, during number plate tasks, the language area (LBA45) was activated, which is a similar result to that reported for a study of Arabic number reading [80]. Nonetheless, language area activation did not occur during non-number tasks in this study.…”

Segregation of Lexical and Sub-Lexical Reading Processes in the Left Perisylvian Cortex

“…The grapho-phonological conversion linked to the sublexical reading process seems to involve the anterior part of the left supramarginal gyrus. This is in line with our previous works describing the involvement of the supramarginal gyrus in phonological processing of sentence reading [19] and with the existence of a spatial segregation of the phonological process for the 2 different types of script (alphabetic versus arabic number) in this gyrus [18]. This study and the current psycholinguistic models of reading also suggest that the superior temporal gyrus and the more posterior part of the supramarginal gyrus are involved in the phonological output level of the lexical reading process.…”
