“…Other studies have shown that TMS delivered over the right OFA disrupted the participants ability to match faces of two different identities using face stimuli that had been balanced for contrast, spectral power and brightness (Bona et al, 2018) or had been cropped to remove all external features (e.g. face shape and hair) (Solomon-Harris et al, 2013). These results again demonstrate that the stimuli in identity discrimination tasks of the OFA typically use faces that have subtle physical differences.…”

Faces are rich sources of social information that simultaneously convey someone’s identity, attentional focus, and emotional state. Humans process this wealth of socially relevant information in a network of face-selective regions distributed across the brain. In this chapter I review studies that have used transcranial magnetic stimulation (TMS) to study the cognitive operations and functional connections of this network. TMS has disrupted brain areas contributing to the processing of facial identity, facial expression, eye-gaze direction, head direction, trustworthiness and the auditory-visual integration of speech. TMS can also be combined with neuroimaging techniques to study how transient focal disruption of a targeted face area impacts connections across the extended face network. I also review chronometric TMS studies that have established when faces are processed across different brain areas down to a millisecond resolution.

“…Facial processing has been previously examined in various studies by non-navigated TMS (Pitcher et al, 2007; Atkinson and Adolphs, 2011; Solomon-Harris et al, 2013), by fMRI (Keenan et al, 2000; Gauthier et al, 2000; Hadjikhani and De Gelder, 2002), and in several brain lesion studies (Hier et al, 1983; Young et al, 1993; Rapcsak et al, 1998; Barton, 2014; Busigny et al, 2014). Nonetheless, nTMS, with its much higher spatial resolution and therefore increased usefulness for neuroscientists, has not been used in this context before.…”

Background: Besides motor and language function, tumor resections within the frontal and parietal lobe have also been reported to cause neuropsychological impairment like prosopagnosia.Objective: Since non-navigated transcranial magnetic stimulation (TMS) has previously been used to map neuropsychological cortical function, this study aims to evaluate the feasibility and spatial discrimination of repetitive navigated TMS (rTMS) mapping for detection of face processing impairment in healthy volunteers. The study was also designed to establish this examination for preoperative mapping in brain tumor patients.Methods: Twenty healthy and purely right-handed volunteers (11 female, 9 male) underwent rTMS mapping for cortical face processing function using 5 Hz/10 pulses. Both hemispheres were investigated randomly with an interval of 2 weeks between mapping sessions. Fifty-two predetermined cortical spots of the whole hemispheres were mapped after baseline measurement. The task consisted of 80 portraits of popular persons, which had to be named while rTMS was applied.Results: In 80% of all subjects rTMS elicited naming errors in the right middle middle frontal gyrus (mMFG). Concerning anomia errors, the highest error rate (35%) was achieved in the bilateral triangular inferior frontal gyrus (trIFG). With regard to similarly or wrongly named persons, we observed 10% error rates mainly in the bilateral frontal lobes.Conclusion: It seems feasible to map the cortical face processing function and to generate face processing impairment via rTMS. The observed localizations are well in accordance with the contemporary literature, and the mapping did not interfere with rTMS-induced language impairment. The clinical usefulness of preoperative mapping has to be evaluated subsequently.

“…Moreover, these lesion studies cannot determine if the site of the lesion was face-selective prior to brain damage. TMS cannot be applied to ventral occipito-temporal areas (e.g., in the FG), so that TMS-evoked impairments in face processing have been found only following stimulation of the lateral occipital cortex (right OFA, e.g., Pitcher et al, 2007;Solomon-Harris et al, 2013) or of the lateral temporal cortex (pSTS, e.g., Dzhelyova, Ellison, & Atkinson, 2011). Moreover, these significant TMS effects concern decreases of a few percent in accuracy rates and/or increase in RTs in face discrimination tasks, but no interruption of the ability to recognize faces.…”
