In our work, we study how short-term memory and long-term memory work together. We use laboratory tasks that ask people to look for a certain object. This task is like looking for your lost keys in your house. We have people look for a specific object in array after array of objects. As you would expect, people get better as this task each time they do it. What our measures of brain activity allow us to do is see how short-term memory and long-term memory simultaneously contribute to the performance of this task. What our studies have been showing is that both of those types of memory storage contribute to how we process information at the same time. Our more recent experiments have looked at how brain stimulation improves task performance and accelerates learning. What our simultaneous measurements of brain activity show is that long-term memory appears to be the source of this accelerated learning, even though it is unfolding across just a matter of seconds to minutes.

The 20 minutes are up sooner than I imagined. I peel the device from my forehead, remove the underlying disposable electrodes, replace my glasses. The difference, I must admit, is palpable: Everything seems more finely etched, crisper. I notice more details in the world around me, and the sense of dullness that three days spent listening to press pitches from moribund industry giants has draped over my brain seems to have been peeled away. Andrew’s experience is less dramatic—he says he definitely feels more relaxed, but you can’t get less anxiety than zero. The up elevator, meanwhile, doesn’t have the same ceiling.
