The power of the human brain to remember is limited, according to a professor of psychology and neuroscience.

Citing the latest research, Dr. Charan Ranganath, director of the Dynamic Memory Lab at the University of California, told CNN’s podcast “Chasing Life,” hosted by chief medical correspondent Dr. Sanjay Gupta, that people can remember only three or four things at a time.

But Ranganath said there is a way “to stuff more information inside your head.”

“Don’t try to remember more, remember better,” he advised. “Sometimes remembering better means memorizing less.”

Ranganath also suggested ways to deal with forgetfulness. One is by attaching “meaning” to information that needs to be remembered. Another is by associating it with a distinction or sensation.

Meanwhile, the power to memorize is not based on the size of the brain.

Researchers at the University of Exeter (UoE) in England studied a mother insect that could remember up to nine of its own nests among the hundreds of other nests in a colony in Surrey.

“We tend to think that something so small couldn’t do something so complex. In fact, they can remember where and when they had fed their young and what they fed them in a way that would be taxing even to human brains,” UoE Professor Jeremy Field said, reported the BBC.

Field was referring to mother digger wasps which, they observed, “rarely make errors in revisiting their nests,” with “only 1.5 percent of the 1,293 food deliveries in the study going to other females’ nests.”

Further, digger wasps feed their young in age order, adjusting the order if one dies, and they can even delay feeding their offspring that had more food in the first visit,” according to BBC.
