The inferior longitudinal fasciculus (ILF) is a long-range, associative white matter pathway that connects the occipital and temporal-occipital areas of the brain to the anterior temporal areas. In view of the ILF’s anatomic connections, it has been suggested that this pathway has a major role in a relatively large array of brain functions. Until recently, however, the literature data on these potential functions were scarce. Here, we review the key findings of recent anatomic, neuromodulation, and neuropsychological studies. We also summarize reports on how this tract is disrupted in a wide range of brain disorders, including psychopathologic, neurodevelopmental, and neurologic diseases. Our review reveals that the ILF is a multilayered, bidirectional tract involved in processing and modulating visual cues and thus in visually guided decisions and behaviors. Accordingly, sudden disruption of the ILF by neurologic insult is mainly associated with neuropsychological impairments of visual cognition (e.g., visual agnosia, prosopagnosia, and alexia). Furthermore, disruption of the ILF may constitute the pathophysiologic basis for visual hallucinations and socio-emotional impairments in schizophrenia, as well as emotional difficulties in autism spectrum disorder. Degeneration of the ILF in neurodegenerative diseases affecting the temporal lobe may explain (at least in part) the gradual onset of semantic and lexical access difficulties. Although some of the functions mediated by the ILF appear to be relatively lateralized, observations from neurosurgery suggest that disruption of the tract’s anterior portion can be dynamically compensated for by the contralateral portion. This might explain why bilateral disruption of the ILF in either acute or progressive disease is highly detrimental in neuropsychological terms.

“…This would exclude mere IFR difficulties without complete impairment of the function, which are found in a large fraction of the population with right posterior brain damage (Benton & Van Allen, ; Valentine, Powell, Davidoff, Letson, & Greenwood, ; Young, Newcombe, de Haan, Small, & Hay, ), but also IFR impairments occurring during development, in a system that has not reached a high level of expertise at IFR (i.e., no ‘childhood prosopagnosia’, Young & Ellis, ). In the same vein, IFR difficulties in patients with a long history of temporal epilepsy (e.g., Drane et al ., ), neurodegenerative disorders such as Alzheimer's disease (e.g., Lavallée et al ., ), the right temporal pole variant of frontotemporal dementia (Rtv‐FTLD (e.g., Busigny, Robaye, Dricot, & Rossion, ; Joubert et al ., ) or yet diffuse low‐grade gliomas (e.g., Corrivetti, Herbet, Moritz‐Gasser, & Duffau, ) should not be labelled (i.e., put in the same basket) as cases of prosopagnosia.…”

The sudden inability to recognize individual faces following brain damage was first reported in a scientific journal 150 years ago and termed ‘prosopagnosia’ 70 years ago. While the term originally identified a face‐selective neurological condition, it is now obscured by a sequence of imprecisions. First, prosopagnosia is routinely used to define symptoms of individual face recognition (IFR) difficulties in the context of visual object agnosia or other neurological conditions, or even in the normal population. Second, this over‐expansive definition has lent support to a long‐standing within‐category recognition account of prosopagnosia, that is, that the impairment of IFR reflects a general impairment in recognizing within‐category objects. However, stringent experimental studies of classical cases of prosopagnosia following brain damage show that their core impairment is not in recognizing physically similar exemplars within non‐face object categories. Instead, the impairment presents specifically for recognizing exemplars of the category of faces. Moreover, compared to typical observers, the impairment appears even more severe for recognizing individual faces against physically dissimilar than similar distractors. Here, I argue that we need to limit accordingly our definition of prosopagnosia to a clinical (i.e., neurological) condition in which there is no basic‐level object recognition impairment. Other criteria for prosopagnosia are proposed, with the hope that this conservative definition enables the study of human IFR processes in isolation, and supports progress in understanding the nature of these processes.

“…It often occurs in cases with bilateral lesions in the occipital temporal cortex, especially the fusiform gyrus (Damasio et al, 1982), but also due to unilateral lesions in the right occipital temporal cortex (Benton, 1990;Takahashi et al, 1995;Wada and Yamamoto, 2001) and, in rare occasions, even on the left side (Mattson et al, 2000). Such lesions can be a side effect of neurosurgical operations of epilepsy or brain tumor (Mesad et al, 2003;Barton, 2008;Corrivetti et al, 2017). Generally, functional deficits are prevented, or at least reduced, by means of neuroimaging techniques.…”

Face recognition is impaired in patients with prosopagnosia, which may occur as a side effect of neurosurgical procedures. Face selective regions on the ventral temporal cortex have been localized with electrical cortical stimulation (ECS), electrocorticography (ECoG), and functional magnetic resonance imagining (fMRI). This is the first group study using within-patient comparisons to validate face selective regions mapping, utilizing the aforementioned modalities. Five patients underwent surgical treatment of intractable epilepsy and joined the study. Subdural grid electrodes were implanted on their ventral temporal cortices to localize seizure foci and face selective regions as part of the functional mapping protocol. Face selective regions were identified in all patients with fMRI, four patients with ECoG, and two patients with ECS. From 177 tested electrode locations in the region of interest (ROI), which is defined by the fusiform gyrus and the inferior temporal gyrus, 54 face locations were identified by at least one modality in all patients. fMRI mapping showed the highest detection rate, revealing 70.4% for face selective locations, whereas ECoG and ECS identified 64.8 and 31.5%, respectively. Thus, 28 face locations were co-localized by at least two modalities, with detection rates of 89.3% for fMRI, 85.7% for ECoG and 53.6 % for ECS. All five patients had no face recognition deficits after surgery, even though five of the face selective locations, one obtained by ECoG and the other four by fMRI, were within 10 mm to the resected volumes. Moreover, fMRI included a quite large volume artifact on the ventral temporal cortex in the ROI from the anatomical structures of the temporal base. In conclusion, ECS was not sensitive in several patients, whereas ECoG and fMRI even showed activation within 10 mm to the resected volumes. Considering the potential signal drop-out in fMRI makes ECoG the most reliable tool to identify face selective locations in this study. A multimodal approach can improve the specificity of ECoG and fMRI, while simultaneously minimizing the number of required ECS sessions. Hence, all modalities should be considered in a clinical mapping protocol entailing combined results of co-localized face selective locations.
