Virtual Dyscalculia Induced by Parietal-Lobe TMS Impairs Automatic Magnitude Processing

Roi Cohen Kadosh, Kathrin Cohen Kadosh, Teresa Schuhmann, Amanda Kaas, Rainer Goebel, Avishai Henik, Alexander T. Sack
2007 Current Biology  
People suffering from developmental dyscalculia encounter difficulties in automatically accessing numerical magnitudes [1] [2] [3] . For example, when instructed to attend to the physical size of a number while ignoring its numerical value, dyscalculic subjects, unlike healthy participants, fail to process the irrelevant dimension automatically and subsequently show a smaller size-congruity effect (difference in reaction time between incongruent [e.g., a physically large 2 and a physically

Previous imaging studies determined the intraparietal sulcus (IPS) as a central area for numerical processing [4] [5] [6] [7] [8] [9] [10] [11] . A few studies tried to identify the brain dysfunction underlying developmental dyscalculia but yielded mixed results regarding the involvement of the left [12] or the right [13] IPS. Here we applied fMRI-guided TMS neuronavigation to disrupt left-or right-IPS activation clusters in order to induce dyscalculic-like behavioral deficits in healthy volunteers. Automatic magnitude processing was impaired only during disruption of right-IPS activity. When using the identical paradigm with dyscalculic participants, we reproduced a result pattern similar to that obtained with nondyscalculic volunteers during right-IPS disruption. These findings provide direct evidence for the functional role of right IPS in automatic magnitude processing. Results fMRI Data Results for the whole-brain group and the behavioral data are presented in detail in the Supplemental Data available online. In line with previous studies [6, 8, 14] , the size-congruity effect activated the bilateral intraparietal sulcus (IPS) (Figure 1 ). In order to accurately stimulate the functionally defined region of interest along the IPS for each participant in the transcranial magnetic stimulation (TMS) experiment, we analyzed the IPS size-congruity-effect activation for each individual separately. The results revealed considerable interindividual differences in the IPS activation both in extent and in layout and, therefore, in the stimulated coordinates ( Figure 2 , Table S1 in the Supplemental Data). TMS Analysis The mean reaction times (RTs) were subjected to a three-way analysis of variance (ANOVA) with TMS (left, right, or left/right sham), comparison (numerical or physical-size comparison), and congruency (incongruent, neutral, or congruent) as within-subject factors. The main effects for congruency (congruent, 447 ms; neutral, 471 ms; incongruent, 531 ms) [F(2,8) = 13.96, p < 0.005] and comparison (physical, 449 ms; numerical, 517 ms) [F(1,4) = 62.07, p < 0.005] were significant. The congruency effect was composed of a facilitatory component (congruent minus neutral) of 24 ms [F(1,4) = 33.43, p < 0.005] and an interference component (incongruent minus neutral) of 60 ms [F(1,4) = 8.99, p < 0.05]. Most importantly, the only factor interacting with TMS was congruency [F(4,16) = 4.17, p < 0.05] (Figure 3) , and the triple interaction was not significant (p > 0.9). Additional analyses of the two-way interaction were conducted separately for each TMS stimulation site [15] . Sham IPS The simple main effect of congruency was significant [F(2,8) = 13.84, p < 0.005]. Examination of the components of the congruency effect revealed a significant facilitatory component of 27 ms [F(1,4) = 57.95, p < 0.005] and a significant interference component of 63 ms [F(1,4) = 8.05, p < 0.05]. Left IPS The simple main effect of congruency was significant [F(2,8) = 11.53, p < 0.005]. The effect was due to significant facilitatory [28 ms, F(1,4) = 30.52, p < 0.005] and interference components [78 ms, F(1,4) = 8.11, p < 0.05]. Right IPS The simple main effect of congruency was significant [F(2,8) = 11.72, p < 0.005]. However, in contrast to results from the other TMS stimulation sites, this significance
