This means that some neurons in the human brain fire together over and over again between three and eight times in 1 s. Remembering all of these different things depends on an electric current that cycle three to eight times per second. Maybe you’re also thinking about what is for dinner, where you’re having dinner, and when you have to be there. ![]() For example, to understand this article, you have to remember what you just read while you are still reading. Normally, you have to remember a lot of things at once. These WM experiments show that the electric currents change depending on how much information you remember. When neurons are active, they deliver very small electric currents (much smaller than currents from wall sockets). Then, our electrical recordings show us what brain cells called “neurons” do when people remember things after a short time (usually between 1 s and 1 min). We ask people to remember things, such as numbers, words, or pictures. To investigate the working memory (WM) system, we record electrical signals from people’s brains while they hold onto and process pieces of information. We will explain why it is difficult to remember many things at the same time and then show you a few ways to improve your own memory. This article explains how brain cells build memories. While looking at the brain structures tells us where memories are built, it does not tell us how memories are built. For a picture of these brain structures and more information about the hippocampus, have a look at Ref. This part is called the hippocampus, and it is very important for long-term memories, for instance, what you remember about how the brain builds memories tomorrow or another time in the future. Another key player in the memory system is buried deep inside your brain. When you think (or think about thinking!), you use your frontal lobe. One key player is the part of your brain directly behind your forehead. The memory system is built into different parts of the brain. We will tell you about a few tricks that the human brain uses to remember a lot of things at the same time but, first it is important to understand how memory works in the brain. How does the brain support WM? And, what is happening in the brain that limits our capacity to store multiple memories at the same time? How Does the Brain Build Memories? As shown in the numbers experiment, WM has limited capacity. WM activates when you experience and remember events in your life, learn new facts, talk to people, read, and do math. ![]() Working memory (“WM” for short) is the ability to hold onto and process pieces of information. Did you remember more of the numbers this time? You just demonstrated something called working memory. Now, try again but think of the same numbers as a date: 07-04-1776. How did you do? We would guess that you remembered around half of the numbers. Then, close your eyes and try to say them aloud, in order. As an experiment, read these numbers: 07041776. Remembering a lot of things at the same time is difficult. ![]()
