Imagine
looking down through the top of your head onto the cortex of your
brain. You would see that is made up of two halves
called hemispheres: one on the left (the left brain) and
one on the right (the right brain). This is the upstairs part
of your brain!
The left and right brains are
connected by an intricate network of nerve fibres called the corpus callosum.
It was the ancient Egyptians who
first noticed that the left brain tends to control the right side of the body
and the right brain tends to control the left side of the body. Although
each hemisphere is almost identical in terms of structure, each hemisphere
operates in an entirely different way and are associated with very
different activities. This is known as specialization or
lateralization.
To learn more
about the upstairs brain and it's specialisation, use your
mouse to hover over the image below to explore your left
brain, right brain and corpus callosum.
