Figure 4. Gamma-augmentation elicited by naming of ambiguous and unambiguous images.

Figure 4

(A) Presented is the definition of the anatomical regions of interest; this was employed in our previous study (Matsuzaki et al., 2012; Kojima et al., 2013a). Medial occipital region: medial portion of BA 17/18. Polar occipital region: polar portion of BA 17/18. Lateral occipital region: lateral portion of BA 19/37. Inferior occipital-temporal region: inferior portion of BA 19/37. Medial temporal region: BA 27/28/34/35/36. Inferior temporal region: inferior temporal gyrus involving BA 20/37. Middle temporal region: middle temporal gyrus involving BA 21/37. Superior temporal region: BA 22/41/42. Inferior parietal region: BA 39/40. Inferior Rolandic region: BA 4/3/1/2 not more than 4 cm superior from the sylvian fissure. Medial frontal region: medial portion of BA 6/8 and posterior portion of BA 24/32/33. Dorsolateral premotor region: dorsolateral portion of BA 6. Middle/superior frontal region: lateral portion of BA 46/9/8. Inferior frontal region: inferior frontal gyrus involving BA 44/45. Orbitofrontal region: BA 47/11. (B) Red dots: electrode sites showing significant gamma-augmentation elicited by naming of ambiguous images alone. Blue dots: sites showing significant gamma-augmentation elicited by naming of unambiguous images alone. Green dots: sites showing significant gamma-augmentation elicited by both naming tasks. Black dots: sites failing to show significant gamma-augmentation during either naming task.
