Background: Memory enhancement is one of the most challenging issues in neurorehabilitation. Memory functions are affected by different neurological conditions as well as by normal aging. Recent data suggest that it may be possible to improve performance on some of the memory tests by physiological modulation of the activity within a neural loop, which plays a crucial role in the formation and maintenance of associative memory, the main parts of which are the hippocampus and the lateral parietal cortex.
Aim: To examine whether anodal transcranial direct current stimulation (tDCS) over the right parietal cortex would have an effect on associative memory between objects and locations.
Methods: Ten healthy right-handed participants (5 males, aged 20–28) were enrolled in a cross-over placebo-controlled study. We applied 20-min anodal or sham tDCS of 1.5 mA over the P4 site of 10–20 EEG system, and participants completed an object-location test immediately after, as well as 24 h, and 7 da...ys after stimulation. The object-location test consisted of recognition and recall tasks.
Results: For the recall task the repeated measures ANOVA showed a significant main effect of stimulation (F(1,9) = 6.32, p < .05, partial eta squared = .41), the main effect of time (F(2,18) = 3.48, p = .05, partial eta squared = .28), as well as interaction effect (F (2,18) = 4.57, p < .05, partial eta squared = .34). On the other hand, no significant effects were observed on the recognition task.
Conclusions: The results indicate that a single tDCS session over the parietal cortex has the potential to improve delayed recall of object-location associations.
