Too far off? No!
According to a study reported by BBC, memory boosting by electric stimulation is achievable. Of course, at the moment brain stimulation via electric current could only be performed in research labs.
Participants in the study were subject to some slightly itchy, electric stimulation at targeted areas of the brain for 20 minutes daily, for four days in a roll.
At the end of the experiment, the participants’ performance in word-memory games improved, especially for those who had struggled the most with the memory games at the start of the study.
Apparently, stimulating the front of the brain, or the prefrontal cortex, improves working memory, which is required for problem-solving. And stimulating the back of the brain or the parietal cortex? That correlates with improvements in long-term memory.
Such improvements in selective memory are reported to last for at least one month.
