Area of Science:

  • Cognitive Neuroscience
  • Neuroimaging
  • Brain Mapping

Background:

  • The triple-code model posits distinct brain regions for number representations (verbal, visual digits, abstract magnitudes).
  • The number form area for visual digits was hypothesized to be in the ventral occipitotemporal cortex (vOTC).
  • Previous neuroimaging studies show inconsistent results regarding the location of this number form area.

Purpose of the Study:

  • To replicate findings of Grotheer et al. using Price & Ansari's passive viewing task.
  • To investigate if differing analysis methods explain discrepancies in previous neuroimaging results.
  • To rigorously test for bottom-up, sensory-driven, category-specific perception of visual number symbols.

Main Methods:

  • Replication of Grotheer et al.'s study using Price & Ansari's passive viewing paradigm.
  • Utilized contrasts reported in both Price & Ansari (2011) and Grotheer et al. (2016) studies.
  • Focused on passive viewing to assess sensory-driven perception of number symbols versus letters and nonsense symbols.

Main Results:

  • The study successfully replicated the findings of Grotheer et al. by identifying bilateral regions in the ventral occipitotemporal cortex (vOTC).
  • These vOTC regions showed greater activation for visual digits compared to letters and nonsense symbols under passive viewing conditions.
  • Analysis using contrasts from both previous studies confirmed the robustness of the vOTC findings and did not attribute discrepancies to analysis differences.

Conclusions:

  • Bilateral ventral occipitotemporal cortex (vOTC) regions are specifically activated by the visual presentation of number symbols, supporting the number form area hypothesis.
  • Passive viewing tasks are crucial for identifying sensory-driven, category-specific visual perception of number symbols.
  • The findings provide strong evidence for a dedicated neural substrate for visual number representation in the vOTC.
