How does my memory measure up?
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.

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