Next, we used RSA to characterize the fine-grained representational structure. Partial correlation results revealed a posterior-to-anterior gradient: posterior regions coded more for modality, while anterior regions coded more for format.

This pattern may reflect everyday statistics: numerosities within the same format—especially sequential—often co-occur, while cross-format pairings are rare. The brain may internalize these regularities, grouping numerosities by format even across senses.

Cross-decoding in conjunction-defined ROIs revealed shared representations only when numerosities shared temporal structure—even across senses. No significant decoding emerged across formats, even within the same modality.

Humans can perceive numerosity across senses and contexts, but how and where the brain abstracts numerical information from low-level input remains debated. We investigate this question by studying numerical stimuli spanning sensory modalities and presentation formats.
