From: Orthographic familiarity, phonological legality and number of orthographic neighbours affect the onset of ERP lexical effects

(Left) Left sagittal view of swLORETA inverse solution performed on the difference wave obtained by subtracting ERPs to quasi-words from those elicited by words in the time window 345–395 ms. Grid spacing = 5 mm; Tikhonov regularization: estimated SNR = 3; power RMS = 41.3 mV. The solution offered two strong sources of statistically significant activation explaining the surface difference-potential, one located in the left IT gyrus (BA 37), and the other in the right FG (BA37) of the temporal lobe. (Right) Right sagittal view of swLORETA inverse solution performed on the difference wave obtained by subtracting ERPs to quasi-words from those elicited by pseudo-words in the time window 345–395 ms. The linear inverse solution showed that the processing of more familiar non-words was significantly associated with stronger activity in the left FG (BA37) and in the right FG (BA37) of the temporal lobe. Power RMS = 27.7 mV.
