Over the years, the capacity of the human brain has become a question in the medical field. Recently, a US scientist, Paul Reber, a professor of psychology at Northwestern University also discussed the same thing.

Reber revealed that the most important human organ consists of billions of neurons. Each neuron consists of a thousand relationships with other neurons, making connections reach trillions of them. But what is the capacity of the brain?

"If every neuron can only help store one memory, running out of storage space will be a problem. You might only have a few gigabytes of storage space, similar to storage on an iPod or USB flash drive," Reber opens.

But neurons are interconnected so that each one helps with many memories at a time, exponentially increasing the memory storage capacity of the brain for something closer.

"The storage memory is around 2.5 petabytes (or one million gigabytes). For comparison, if your brain works like a digital video recorder on television, 2.5 petabytes will be enough to record three million hours of TV shows. You have to leave the TV on and on "It's been for more than 300 years to use all of that storage," he continued.

Nevertheless, Reber continued that large brain storage capacity is precisely difficult to calculate. First, this is because humans don't know how to measure the size of their memory. Second, certain memories involve more detailed memory and thus take up more space; Other memories are forgotten and thus space becomes free. In addition, some information doesn't need to be remembered.
