“…On the channel level, more negative deflections over right occipito temporal channels are described for the face condition to the scrambled face condition. The topography, latency and response characteristic are consistent with the N170 component 34 . Previous source and simultaneous EEG fMRI investigations report that the fusiform gyrus is a likely generator of the N170 response.…”

EEG is traditionally described as a neuroimaging technique with high temporal and low spatial resolution. Recent advances in biophysical modelling and signal processing make it possible to exploit information from other imaging modalities like structural MRI that provide high spatial resolution to overcome this constraint 1 . This is especially useful for investigations that require high resolution in the temporal as well as spatial domain. In addition, due to the easy application and low cost of EEG recordings, EEG is often the method of choice when working with populations, such as young children, that do not tolerate functional MRI scans well. However, in order to investigate which neural substrates are involved, anatomical information from structural MRI is still needed. Most EEG analysis packages work with standard head models that are based on adult anatomy. The accuracy of these models when used for children is limited 2 , because the composition and spatial configuration of head tissues changes dramatically over development 3 .In the present paper, we provide an overview of our recent work in utilizing head models based on individual structural MRI scans or age specific head models to reconstruct the cortical generators of high density EEG. This article describes how EEG recordings are acquired, processed, and analyzed with pediatric populations at the London Baby Lab, including laboratory setup, task design, EEG preprocessing, MRI processing, and EEG channel level and source analysis.

“…Neural evidence also provides mixed support. Rossion and colleagues replicated the N170 interference effect initially found for greebles (21) in a subsequent study with car experts (44). Furthermore, Gauthier and colleagues reported increased activation to cars and birds in the Fig.…”

Face recognition is generally thought to rely on different neurocognitive mechanisms than most types of objects, but the specificity of these mechanisms is debated. One account suggests the mechanisms are specific to upright faces, whereas the expertise view proposes the mechanisms operate on objects of high withinclass similarity with which an observer has become proficient at rapid individuation. Much of the evidence cited in support of the expertise view comes from laboratory-based training experiments involving computer-generated objects called greebles that are designed to place face-like demands on recognition mechanisms. A fundamental prediction of the expertise hypothesis is that recognition deficits with faces will be accompanied by deficits with objects of expertise. Here we present two cases of acquired prosopagnosia, Herschel and Florence, who violate this prediction: Both show normal performance in a standard greeble training procedure, along with severe deficits on a matched face training procedure. Herschel and Florence also meet several response time criteria that advocates of the expertise view suggest signal successful acquisition of greeble expertise. Furthermore, Herschel's results show that greeble learning can occur without normal functioning of the right fusiform face area, an area proposed to mediate greeble expertise. The marked dissociation between face and greeble expertise undermines greeble-based claims challenging face-specificity and indicates face recognition mechanisms are not necessary for object recognition after laboratorybased training.

“…Although experts and novices showed similar overall performance, early change effects were positively correlated with accuracy across all subjects, and positively correlated with experts' years of experience. Other research has documented expertise-related changes on ERPs (Busey & Vanderkolk, 2005;Gauthier, Curran, Curby, & Collins, 2003;Rossion, Collins, Goffaux, & Curran, 2007;Tanaka & Curran, 2001), but this is the first study to specifically relate early visual effects to change detection ability and duration of related experience by demonstrating that the ERP change effects correlated with both accuracy and years of image analysis experience.…”
