Over the past few years, considerable progress has been done in clarifying the neural networks underlying mentalizing. However, although the cortical architecture of this function is relatively well understood, the white matter pathways that may be involved in conveying neural signals within the mentalizing network remain to be elucidated. To gain insight into this matter, a detailed stimulation mapping of face-based mentalizing was performed in 27 patients undergoing awake surgery for a right-sided diffuse low-grade glioma (DLGG). Direct electrical stimulation (DES) was applied to both the cortical and subcortical levels. In perfect agreement with previous literature using face-based mentalizing tasks, cortical sites were identified in the posterior inferior frontal gyrus (IFG), the dorsolateral prefrontal cortex (dlPFC), and the posterior superior temporal gyrus (pSTG). Most importantly, critical sites were found along the inferior fronto-occipital fasciculus (IFOF), and within the white matter fibres supplying the dlPFC. Disconnectome analyses confirmed the very high probability of IFOF disconnection during temporal subcortical stimulation, and revealed an additional implication of the superior longitudinal fasciculus/arcuate fasciculus (SLF/AF) during prefrontal subcortical stimulations. Altogether, these findings suggest that functional integrity of both the IFOF and the SLF is required for accurately inferring complex mental states from human faces.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 March 2017.
All research outputs
#19,702,729
of 24,217,893 outputs
Outputs from Brain Structure and Function
#1,236
of 1,725 outputs
Outputs of similar age
#244,415
of 315,771 outputs
Outputs of similar age from Brain Structure and Function
#27
of 44 outputs
Altmetric has tracked 24,217,893 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,725 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.0. This one is in the 11th percentile – i.e., 11% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 315,771 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 44 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
