Non-invasive neuromodulation can improve performance on memory tasks, raising the question of its potential as a future therapeutic tool.

Research on non-invasive brain stimulation, particularly transcranial direct current stimulation (tDCS), shows encouraging but complex results. A meta-analysis published in 'Neuroscience & Biobehavioral Reviews' suggests that certain forms of stimulation can effectively modulate cortical excitability and promote learning or working memory. However, the effect is often variable from one individual to another, depending heavily on electrode placement and the timing of the stimulation. It is crucial to note that, contrary to what consumer uses sometimes suggest, current evidence does not guarantee significant and lasting cognitive improvement for a healthy individual. Science remains cautious regarding the reproducibility of results on a large scale. The idea that this could become a standard therapy is therefore still largely at the stage of experimental exploration rather than established clinical application.
