Our brain is our most complexorgan. It’s a command centre foreverything we think, do and feel.
We’re born with almost all the braincells we’ll have throughout our lives,so our brain doesn’t grow as much asit develops.
To do this, it needs neuralconnections—billions of them. Theseconnections—called synapses—aretiny, each about 10,000 times smaller
Our brain thrives on connections
Billions of synapses form in the early years
than the thickness of a piece of paper.
The basic architecture of the
brain is built over time, beginning
before birth and continuing until
we’re adults, with more connections
forming in our first six years than
at any other time in life (we also
go through another spurt of brain
development during our teen years).
During those intensive early years,
our brain makes about 700 new
neural connections every second—
billions by the time we’re three years
It’s no wonder toddlers are burstingwith life, energy and curiosity.
As we grow, our brain continuesto form new neural connections ata slower rate. At the same time, ourbrain also goes through synapticpruning, shutting down some circuitsthat are not used so the remaining
More neural connections are formed in our first six years than at any other time in life, laying the foundation for lifelong health.
