“…Regression models were constructed to predict participant accuracy on the three face tasks. Previous studies have shown diffuse changes in white matter microstructure throughout the whole brain as a function of age as well as general gender differences in white matter connectivity throughout the brain (Gong, He, & Evans, 2011; Ingalhalikar et al, 2014; Lebel et al, 2012; Thomas, Moya, et al, 2008). Therefore, we examined the relationship between the white matter measures in our sample with age and gender.…”

“…Using this framework, we tested the hypothesis that individual differences in ILF microstructure predicted inter-individual variability in face emotion recognition and face memory. In addition we examined two other long-range white matter tracts: the IFOF since there is a small literature linking this tract to face processing (Thomas, Moya, et al, 2008), and the UF as a control fiber pathway, given that our recent literature reviews found no evidence linking this tract to any of the behaviors investigated in this study (Von Der Heide et al, 2013). Our results revealed that microstructure of the right ILF and bilateral IFOF significantly predicted variability in facial emotion recognition performance, as well as face memory performance in healthy young adults.…”

“…ILF scarring or degeneration in multiple sclerosis and/or fronto-temporal dementia correlates with face identification deficits (Grossi et al, 2014; Yamasaki et al, 2004). Also, individuals with developmental or congenital prosopagnosia have reduced structural integrity of the right ILF (Grossi et al, 2014; Thomas, Moya, et al, 2008) which predicts face-recognition impairments (Thomas, Moya, et al, 2008). This raises the question of why we did not observe any effects in our face identity task.…”

“…Electrical stimulation of this tract during neurosurgery consistently results in semantic errors (Duffau, Peggy Gatignol, Mandonnet, Capelle, & Taillandier, 2008) providing strong evidence that this tract plays a significant role in semantic memory. However, there is a hint that it may also play some role in face processing as one study reported reduced structural integrity of the right IFOF in congenital prosopagnosia (Thomas, Moya, et al, 2008). In addition, two studies found a relationship between damage to the right IFOF and emotion recognition impairments (Genova et al, 2015; Philippi et al, 2009).…”

Objective The extended face network contains clusters of neurons that perform distinct functions on facial stimuli. Regions in the posterior ventral visual stream appear to perform basic perceptual functions on faces, while more anterior regions, such as the ventral anterior temporal lobe and amygdala, function to link mnemonic and affective information to faces. Anterior and posterior regions are interconnected by a long-range white matter tracts however it is not known if variation in connectivity of these pathways explains cognitive performance. Methods Here, we used diffusion imaging and deterministic tractography in a cohort of 28 neurologically normal adults ages 18–28 to examine microstructural properties of visual fiber pathways and their relationship to certain mnemonic and affective functions involved in face processing. We investigated how inter-individual variability in two tracts, the inferior longitudinal fasciculus (ILF) and the inferior fronto-occipital fasciculus (IFOF), related to performance on tests of facial emotion recognition and face memory. Results Results revealed that microstructure of both tracts predicted variability in behavioral performance indexed by both tasks, suggesting that the ILF and IFOF play a role in facilitating our ability to discriminate emotional expressions in faces, as well as to remember unique faces. Variation in a control tract, the uncinate fasciculus, did not predict performance on these tasks. Conclusions These results corroborate and extend the findings of previous neuropsychology studies investigating the effects of damage to the ILF and IFOF, and demonstrate that differences in face processing abilities are related to white matter microstructure, even in healthy individuals.
