The human brain has over 100 billion neurons.
These cells are the basis for all
your brain’s activity.
All these neurons are connected in a
network.
Each neuron communicates with many other neurons.
Some cells have
thousands of connections; others, just a few.
The number of connections
between neurons in a human brain is greater than the number of stars in
our sky.
To try to understand the complexity of this network, think
of a city like New York.
Each person is a neuron.
Then multiply the size of the city by 1,000.
The whole city is the brain, and
each person is a neuron in its network, communicating to others.
Neurons are flexible.
They are not bound to each other.
Neurons can make
and break their connections with other neurons.
Every time we learn a new
skill or learn new information, our neurons make new connections.
Networks of
neurons that are used get stronger, and networks of neurons that are not used
are lost.
In this way, the brain changes itself constantly.
Throughout your
life, these changing connections mean you can truly change your mind.
