Summary of the main results in neuroimaging and whole-head magnetoencephalography studies with AN.
| Studies | Clinical Groups Studied | Technique utilized | Brain areas related with AN |
|---|---|---|---|
| Piras & Marangolo (2007) | Aphasia | VLSM | left prefrontal area to left superior temporal area |
| Piras & Marangolo (2010) | Stroke | VLSM | Verbs and verb-nouns: different fronto-temporal regions |
| Libon et al. (2012) | ALS | MRI (cortical thickness) | prefrontal and parietal cortex |
| Daniele et al. (2013) | PSP, HC | SPECT | hypoperfusion inferior frontal gyrus |
| Breier & Papanicolaou (2008) | Healthy subjects | MEG | First activation: lateral occipital cortex bilaterallyLatest activation: pars opercularis, triangular part of inferior frontal gyrus (stronger in left hemisphere) |
| Soros et al. (2003) | Healthy subjects | MEG | Occipital to posterior temporoparietal and further to the left frontal cortex |
AN: action naming; ALS: amyotrophic lateral sclerosis; HC: healthy control; MEG: magnetoencephalography; MRI: magnetic resonance imaging; PSP: progressive supranuclear palsy; SPECT: single-photon emission computed tomography; VLSM: voxel-based lesion symptom mapping.
