Researchers at Wake Forest University Medical Center did a research in monkeys and it could provide a clue (提示) about how the brain manages plenty of information and remembers what it needs. They found that when monkeys were taught to remember computer art pictures, their brains reduced the level of information by sorting the pictures into several kinds for recall, such as pictures that have to do with “people”，“buildings”，“flowers” and “animals”.

The brain sorting cells (细胞) were found in the hippocampus (海马体) an area of the brain that processes sensory(感官) information into memory. It’s important for remembering all things including facts, places, or people. It might lead to some memory illness.

The researchers recorded the cell activity in the hippocampus while the monkeys were performing a memory task. Each monkey was shown one art picture, and after 30 seconds, picked it up from two to six different pictures to get a juice reward.

By recording cell activity during hundreds of these tasks, the researchers noticed that certain cells were more active when the pictures had the similar information, such as pictures of people but not other objects.

The researchers found that, however, that different monkeys sort the same pictures differently. For example, with a picture of a man in a blue coat, some monkeys placed it in the “people”，while others placed it in the “coat”.

“When you need to remember people you’ve just met at a meeting, the brain probably doesn’t memorize each person’s facial expressions,” says Sam, one of the researchers, “Instead, it records important information such as their hairstyle, height, or age, all parts that we are familiar with from meeting people in general. Our research suggests how the brain might do this, which could lead ways to improve memory in human. If we can understand how the brain works when decisions are made, we can predict when the brain will make a mistake, and correct it. This finding about how much information is processed by the brain will help us achieve that goal.”
