Neural Circuits: Our Brain’s Road System
When neurons fire together, circuits are developed, joining different parts of
the brain.
Some actions involve lots of neurons firing all at
the same time.
We call this a neural circuit. It’s a bit like road
system joining different parts of a city – but
instead, the roads are electrical signals linking
neurons in different parts of the brain.
Every time groups of neurons fire together, the brain circuit gets stronger
and faster.
Let’s say you practise kicking a football at a goal.
If you practised again and again, the part of your brain used for kicking accurately
would become denser – there would be thicker brain circuits and more of them.
