Sarah
sat on her doorstep, crying. Her day had been terrible. First she had
gotten a big fat F on her math test. She had studied really hard, but
when she was given the test, she just couldn't remember anything.
Then at recess she tripped and fell into a puddle. All the other kids
laughed at her and told her she was clumsy. Sarah tried not to cry,
but she couldn't help it. Then the other kids laughed more because
they thought she was a crybaby. Sarah never wanted to go back to
school. Everyone just thought she was dumb.
Out
of the corner of her eye, Sarah suddenly saw the bushes shake.
Scared, she jumped off the step. An ugly little creature flew out of
the bushes and landed on the sidewalk.
“Hi!”
he said.
The
little creature looked like something she had seen in her science
book. “Who are you?” Sarah asked.
“I
am Super Brain!” he replied. “I am here to help you.”
“Help
me? How? You're so small!” Sarah exclaimed.
“I
may be small, but I'm really smart. I can help you do a lot of
things.” Super Brain jumped closer.
What
are all those wormy things on your face?” Sarah asked.
Super
Brain laughed. “Those are called convolutions. They make up my
outer layer called the cortex. My cortex is divided up into sections
called lobes. This very back lobe is called the Occipital lobe. It is
what I use to help people see.”
“Wow!
What do the other lobes do?” Sarah was beginning to like Super
Brain, even if he was a little ugly.
Super
Brain pointed to the next lobe. “This one is called the parietal
lobe. It helps people feel things like pain and cold or hot.” He
then pointed to his sides. “These ones are called Temporal lobes,
and they help people hear. This last one, called the frontal lobe,
helps people with things like talking, math, and science.”
“Do
you do anything else?” Sarah asked.
“Yep!
There is a lot more that I can do,” Super Brain replied. “I can
also be divided into two sides called hemispheres. My right side
controls things like emotions and artistic and musical skills. The
left side is the logical side. It likes things like math and science
and also helps with speech.” Super Brain then pointed to his
middle. “Inside me, my corpus callosum hold the two sides together.
Together, they make up the cerebrum. Some other parts of me include
the Thalamus, Hypothalamus, and Hippocampus.”
Sarah
giggled. “Is that for hippos?”
Super
Brain laughed. “No, that is the part of me that stores short term
memories, changing them into long-term memories, so you don't ever
forget.”
“Oh,”
Sarah laughed.
“The
thalamus is kind of like a policeman directing traffic. It makes sure
all my important information gets to the right place and back. The
hypothalamus can control things like thirst and hunger,” Super
Brain finished.
Sarah's
stomach growled. “I think I'm hungry right now.” She needed to go
eat supper, but she saw one more thing she wanted to know about.
“What is that on your back?” she asked Super Brain.
“That
is called a brainstem. Part of the brainstem, called the medulla,
controls things like heartbeat and breathing. This other part back
her is called the cerebellum, and it helps with things like keeping
your balance while riding your bike or dancing.”
“Wow,
Super Brain, you are really amazing!” Sarah exclaimed.
Super
Brain winked. “God made me amazing, Sarah!”
The
next day at school, Sarah wasn't afraid of having a terrible day. She
knew Super Brain would help her, and she would do better. When she
sat down to take another test, she heard him whisper, “You can do
it, Sarah!”
Yummy...the idea of a brain hopping around and talking to me is...a comforting thought.
