8/ We believe this work offers new insights into the IFOF’s role beyond semantics and invites further exploration into its broad executive functions.

7/ Clinically, this pathway’s importance in neurosurgery is clear: it should be considered a key target for preservation in both hemispheres (against the myth of a non-dominant right hemisphere).

6/ This unified view links language, visual processing, motor cognition, theory of mind, reading, attention, and emotion recognitionβ€”grounding cognitive control in top-down modulation of visual features. It also posits a role for the right IFOF in social semantic control.

5/ Using stimulation, we propose it can be subdivided in two-layers:
πŸ”Ή Ventral IFOF: Cognitive control for conceptual/symbolic content (including language).
πŸ”Ή Dorsal IFOF: Cognitive control for perceptual content

4/ We propose that the IFOF overlays cortical regions involved in semantic control and the multiple demand system, representing an executive, prefrontal connection for top-down modulation of visual features. It is language-sensitive, but not language-specific.

3/ Our review challenges the idea that the IFOF evolved for language. Gathered data indicate that this pathway is present along the primate lineageβ€”far earlier than languageβ€”suggesting it originally supported top-down cognitive control of visual features for goal-directed behaviour.

2/ Since then, the IFOF has been considered the major anatomical pathway linking language to meaning, but objections have emerged suggesting its function goes beyond language.
