Arcuate fasciculus' middle and ventral temporal connections undercut by tract-tracing evidence

Controversy over the temporal cortical terminations of the left arcuate fasciculus: a reappraisal

Davide Giampiccolo et al.

Summary: The arcuate fasciculus, a white matter pathway in the dorsal fronto-temporal region, has been traditionally believed to link frontal language production regions with auditory perception in the temporal lobe. However, recent research findings indicate that the projections of the arcuate fasciculus may not be unique to the temporal lobe and that it may also play a role in other regions involved in language processing.

The Arcuate Fasciculus and language origins: Disentangling existing conceptions that influence evolutionary accounts

Yannick Becker et al.

Summary: The study discusses the importance of the Arcuate Fasciculus (AF) in language brain evolution and the issues in existing research, including the impact of different research methods and nomenclatures on AF conceptions, as well as four key evolutionary changes. The research concludes that the anatomy of the AF across primates may be more shared than previously described, providing new insights for language evolution theories.

Hodology of the superior longitudinal system of the human brain: a historical perspective, the current controversies, and a proposal

Laura Vavassori et al.

Summary: The description of human white matter pathways has greatly improved, but has also led to redundant and conflicting literature. This study provides a comprehensive illustration of the Superior Longitudinal System (SLS) and aims to address discrepancies in the field by proposing a unified approach in nomenclature and methodology.
