 Abstract: The ability to create structures out of single words is a key aspect of human language. This combinatorial capacity relies on a low-level syntactic mechanism—Merge—assembling words into hierarchies. Neuroscience has explored Merge by comparing syntax to word-lists. Here, we first review potential issues with the word-lists materials. We then perform an activation likelihood estimation (ALE) on the reported foci, to reveal functional convergence for Merge at whole-brain level. Finally, we run probabilistic tractography on an independent population to observe how these convergent activations anatomically connect. Functionally, we found that when confounding activity was removed, consistency for Merge was only observable in the left pars opercularis (BA44) and in the inferior part of the posterior superior temporal sulcus/gyrus (pSTS/STG; BA22). Structurally, we could confirm that the two regions are connected through dorsal fiber bundles. We therefore suggest that the cortical implementation of linguistic Merge consists of a left fronto-temporal interaction between BA44 (syntactic processor) and pSTS/STG (integrative processor), which communicate to each other along dorsal white matter fascicles.
