A good memory will often naturally decrease as years pass. It’s an unwritten law of human nature, but the good news is that we can improve our ability to remember stuff through various processes. One of them is magnetic brain stimulation, as a new study revealed by SciTechDaily.com has found.
More precisely, low frequency repetitive transcranial magnetic stimulation (aka rTMS) that’s delivered over the brain’s left prefrontal cortex will improve memory.
Episodic memory is targetted
The scientists supposed that they could improve episodic memory, meaning a neurocognitive system that’s uniquely different from other memory systems and that helps us remember experiences from the past. Also, they’re optimistic that they could generate targets of future therapies related to memory.
Simon Hanslmayr from the University of Glasgow and also one of the new study’s authors, declared as quoted by SciTechDaily.com:
Our electrophysiological results suggest that frontal stimulation affects a wider network and improves memory formation by inhibiting parietal areas. These are complex but interesting effects that require further experiments to better understand their neural basis.
We were quite surprised when we saw these effects in the first study, which was designed to investigate a different question. Therefore, we needed to replicate the effects in a second experiment to see whether this is real, and indeed it seems to be.
Forty college students had their data analyzed as they were asked to memorize words from a list. Half of these students were given slow rTMS for the left dorsolateral prefrontal cortex as they were trying to remember the words. As for the other half, they were given rTMS for a control region of their brains. For another experiment, data were collected from 24 college students who performed a similar task under both of the rTMS conditions. The conclusion was that memory performance was better in the case of words that were memorized as the left prefrontal cortex was being stimulated.
The new study was published in PLOS Biology.
