We've all felt the desire to improve our cognitive abilities. A new tool, Transcranial Magnetic Stimulation, might provide that extra boost we've been looking for.

Our cognitive capacities influence just about everything we do. We've all heard about ways of improving performance: a good night's sleep, proper diet, exercise – you've heard it all before.

Neuroscientists might have found a more technologically inspired method of improving brain function. Transcranial Magnetic Stimulation (TMS) manipulates brain activity on the surface areas of the brain.

So far, neuroscientists have used TMS to improve memory, reaction times, and many other cognitive abilities. Despite these promising results, the long-term effects are ill-understood. Will this novel technology become as commonplace as smartphones, or has our obsession with technological improvements gone too far?

Life: Connected is a video series from BBC Future focusing on how digital culture and technologies pervade everything we do.
