The representation of semantic knowledge in the human brain (2007, methodology): “One study compared the functional activation revealed by PET and by fMRI (using a standard whole-brain acquisition sequence) in a group of people performing a semantic categorization tas”
Image Distortion Correction in fMRI: A Quantitative Evaluation (2002, methodology): “This susceptibility-induced signal loss is a related artefact that currently limits the use of EPI for tasks involving regions in the temporal and frontal lobes (Ojemann et al., 1997; Devlin et al., 2000; Gorno-Tempini et al., 2001).”
A cortical network for semantics: (de)constructing the N400 (2008, background): “However, the anterior temporal cortex is known to be susceptible to fMRI signal artefacts, particularly in the medial region that has been implicated in N400 response generation by the intracranial studies discussed belo”
Semantic impairment in stroke aphasia versus semantic dementia: a case-series comparison. (2006, background): “Functional neuroimaging studies of normal participants performing semantic tasks point to a broadly similar neural network (as long as the findings of PET as well as fMRI studies are taken into account; Devlin et al., 2000).”
Semantic Processing in the Anterior Temporal Lobes: A Meta-analysis of the Functional Neuroimaging Literature (2010, methodology): “This key result from themeta-analysis aligns closely with Devlin et al. (2000) who demonstrated significant ATL activation in a semantic task using PET but not fMRI in a direct comparison of these two imaging methodologies.”
The Enigmatic temporal pole: a review of findings on social and emotional processing. (2007, background): “…could either mean that the TP is insensitive to the task or stimulus or it could simply reflect the fact that air-tissue inhomogeneities, a problem in imaging all neural regions near the sinuses, have diminished the BOLD signal to such a degree that no activations are visible (Devlin et al., 2000).”
Coming of age: A review of embodiment and the neuroscience of semantics (2012, unknown): “…functional imaging of the regions around the anterior temporal lobes (ATLs) has been hindered by signal drop out (e.g. Schwarzbauer et al, 2009; Devlin et al, 2000), but other techniques, such as repetitive Transcranial Magnetic Stimulation (rTMS) have produced converging evidence for the role…”
Predicting regional neurodegeneration from the healthy brain functional connectome. (2012, methodology): “…threshold of p < 0.05, FDR corrected for multiple comparisons, was used for the SD pattern to adjust for the fMRI signal loss characteristic of the temporal pole and orbitofrontal regions contained in this network, following previous approaches (Devlin et al., 2000; Seeley et al., 2009).”
