The human brain
contains from 50100 thousand
million (1011) cells
called neurons.
Each neuron is
connected to
about 10,00020,000 other
neurons.
The Human Brain
The human brain
has capacity to
store about 20
thousand books
of about 500
pages and 400
hundred words
per page.
The Human Brain
In these connections our brain stores and
processes all our past memories, the faces
of all people we know, stories, films, the
taste of our favorite meals, all the books
we have read, etc.
The Human Brain
We know that the brain is divided in two
symmetrical sections called hemispheres:
The hemispheres are join in
the middle for what is called
corpus callosum, a thick
bundle of some 300 million
nerve fibers that connects
the brain’s two hemispheres

In the 1860’s, Paul Broca discovered that
the left hemisphere controlled the ability
to speak language.
In the 1870’s, Carl Wernicke discovered
that the left hemisphere was as well in
charge of understanding language.

Brains scientists have realized that the two
hemispheres had different functions.
