How does your brain work?

You’ve come to the right place to find out. This section of the Hello Brain website describes that amazing three pounds (1.36 kg) of ever-active tissue inside your head.

Have a look around this part of the website to find out how your brain is divided up into different regions that all have their roles to play in keeping you thinking, feeling and doing.

We’ll be looking at the billions of cells that carry all-important information around your brain, the support systems that keep you going and how your brain changes over time.

You’ll find out that your brain is plastic (yes, really!) and how this means your brain can adapt to new information and experiences.

You’ll learn about the concept of ‘cognitive reserve’ – a protective reserve that seems to help some people avoid the symptoms of brain ageing or injury.

You’ll find out more about memory and attention – how do they work? Why are they important?

And we’ll take a glimpse into the future of brain research

Ready? Scroll down to get started.
