Location of the left Anterior Temporal Lobe site to which repetitive Transcranial Magnetic Stimulation was applied. Crosshairs represent site of stimulation, corresponding to the co-ordinates -53, 4, -32 in MNI space.

Figure 3). For stimulation, this site was determined by co-registering cortical surface with 11 anatomical landmarks (inion, tip of the nose, left/right ear canals and left/right ear projections) some of which were marked prior to the scan with oil capsules (vertex, nasion, left/right ear tragus, and beneath lip in chin indentation).
Average reaction times for naming of high and low typicality pictures before and after the application of repetitive Transcranial Magnetic Stimulation to the left Anterior Temporal Lobe. Error bars represent +- within-participants 90% confidence intervals computed according to Loftus and Masson (, Equation 4, p. 485).

Figure 4, revealed a non-significant main effect of rTMS (F1(1, 15) = 0.51, p = 0.486; F2(1, 78) = 0.81, p = 0.371) and a main effect of typicality reliable by participants but not by items (F1(1, 15) = 5.48, p = 0.033; F2(1, 78) = 0.78, p = 0.389), which were qualified by an reliable interaction between the two, albeit it of marginal significance by participants (F1(1, 15) = 3.67, p = 0.075; F2(1, 78) = 9.99, p = 0.002). Follow-up one-tailed t-tests revealed that while the typicality effect was not significant prior to rTMS (t1(15) = 0.11, p = 0.480; t2(78) =.34, p = 0.368), it was after rTMS (t1(15) = 2.74, p = 0.008; t2(78) = 1.90, p = 0.031).
