1. Exploring the human hard drive

Whether it’s remembering our route to work, finding the keys we just put down or making sure that birthday card is posted, we all rely on our memories every day.

Most people can remember and retrieve massive amounts of information, including thousands of names and faces, different bank PINs and complex directions.

A select few can achieve amazing feats of memory, with minds that never forget. But our powers of recall pale in comparison to some other species.

We may not have the scent recognition of an elephant or a cat's short-term memory, but the human brain is the most complex machine that exists. A tiny number of people even possess "super memory".

3. Total recall

When someone has super memory, also known as hyperthymesia, their minds retain everything they process.

Rachel Riley on hyperthymesia and the only known case of this condition in the UK.

There are only a handful of cases of hyperthymesia in the world. It's controversial, and some think it doesn't even exist. But whether you have super memory or not, your brain is quite brilliant. It's made up of billions of interconnected neurons, which communicate through thousands of connections called synapses. When a connection between these is strengthened, a memory is formed. This is what our memory is based on – millions of tiny connections in our brains.

4. 86 billion brilliant bits

Some experts estimate that we can save and process about 100 terabytes of information in our heads. Click on the labels to discover the bits that make our memory work.

5. Is human memory becoming obsolete?

With the storage capability of the internet, some people argue human memory is a thing of the past. What do you think?

Yes

Digital is the way forward.

Yes

Not remembering useless trivia and facts gives our brains more capacity to think about and process more important things.

No

Brain is best.

No

If the internet went offline forever we'd lose all our information. Cerebral retrieval is the best way to form enduring memories.

Maybe

A bit of both.

The brain is incredibly powerful. Joined with the storage capacity of the internet and speed of computer processing, the human race can achieve the incredible.
