If you read the previous blog post on TDCS, then you will quickly understand the basics of Transcranial Magnetic Stimulation (TMS). A group led by Joel Voss at Northwestern just published a small study (16 people) in the Journal Science showing that after intensive fMRI brain mapping and five 20-minute TMS sessions, participants improved memory performance by 30%. This is quite amazing and in line with other studies. The key to this study is that the researchers first mapped the brain determining which regions of the brain synched closely with hippocampal neural networks. While a 30% improvement in memory is amazing, the work and cost involved make this technique unsuitable for the average person. However, there are easier ways to improve memory!
A couple of years ago, I published a slightly larger study (62 Stanford students) in the Journal of Appetite showing that chewing Think Gum improved memory by over 25%. The great thing about Think Gum is that it requires no brain mapping, no fMRI, no team of neuroscientists and no TMS device. All you need is $2.49 and a mouth.
