Fig. 4: Correlations with the theoretical RDMs in Exner’s area and left hippocampus.

During the study period, multi-voxel activation patterns in Exner’s area showed a significant effect of learning condition for the motor RDM (p = 0.013, shaded in gray). The main effects and their interaction were non-significant for the three RDMs during the test period (p > 0.1 for all). On the other hand, the left hippocampus showed significant crossover interaction with the syllabic RDM (p = 0.023), suggesting that handwriting yielded a differential impact on activation patterns between the blind and sighted groups. During the test period, the same segment of the left hippocampus showed significant condition × group interaction for the semantic RDM (p = 0.026), again suggesting that semantic information was more weakly represented for the blind relative to the sighted participants.
