Almost seems like science fiction, doesn’t it? Not quite what I expected to see in the latest New England Journal of Medicine. 

It’s a small study, of only seven patients (that were awaiting epilepsy surgery). The task to remember involved learning landmarks within a virtual space. Stimulating the entorhinal cortex improved memory, however stimulating the hypothalamus directly didn’t make much difference.

An interesting proof-of-concept – I can see this being used in all kinds of applications, from the military to medicine – but it’s a long way from practical application just yet.
