Abstract Spatial memory relies on efficient encoding, storage and retrieval of spatial information, which enables us to remember paths or locations objects in everyday life. Moreover, this type has been shown decline with age various neurodegenerative disorders. Parietal cortex play an important role the formation short-term representations information. The aim current study was test possibility immediate long-term enhancement, by increasing excitability parietal posterior cortex. We used transcranial direct stimulation (tDCS) over a placebo-controlled cross-over study. Participants received anodal (1.5 mA) sham tDCS P4 site (10-20 EEG system) for 20 minutes two separate sessions. Immediately after stimulation, participants completed maze task, consisted learning block, 2D recall, 3D recall. performance tested 24 hours 7 days assess potential effects. found no significant effects either delayed This case both, Our results are line some studies that suggest single brain sessions do not always produce cognitive functions.
