Schematic representation of the proposed functional organisation of the LIFG. The anterior-posterior organisational axis (represented by the horizontal blue-to-green arrow) might reflect a shift from lower-order perceptual processing (posterior LIFG) via affiliation with the SMN and VAN, and higher-order cognitive control (anterior LIFG) via affiliation with the FPN and DN. The dorsal-ventral axis (represented by the vertical orange-to-red arrow) might reflect a shift from domain-general executive functions (dorsal LIFG) via affiliation with the FPN and DAN and the cognitive control of information stored in long-term memory (ventral LIFG) via affiliation with the DN/SN. The word clouds illustrate functional terms associated with the LIFG clusters located at the extremes of the task-free and task-based gradients in the forward or reverse inference functional decoding analyses - terms associated with the anterior but not posterior cluster (blue); the posterior but not anterior cluster (green); the dorsal but not ventral cluster (red); the ventral but not dorsal cluster (orange); and with all four clusters (grey). The size of the word reflects the effect size of the association.
