Essay/Term paper: The brain 's cerebral cortex
Essay, term paper, research paper: Biology
The brain is three pounds of tissue that are part of the nervous system. It
is one of the two basic parts and contains a bout 100 billion nerve cells.
The glilia is the cells that take care of the neuron cells ands allow the
nueroin cells to carry out all of the impulses and messages that they must
send. It is divided in to parts that give you the ability to do everything
from swimming to math and more.
The brain has two hemispheres, which are mirror images of each other ,the
right and left. The cerebral cortex of the brain is the main processing
center of the brain. The surface is made up of surface of sulci and gyri.
Your brain has two sides ,and each has a distinctly different way of looking
at the world. The more we integrate those two sides, the more developed we
make ourselves. Integration not only increases our ability to creatively
solve problems, but to control physical problems such as epilepsy and
migraines. Even more startling is evidence coming to light that we have
become a "left-brain culture".
Your brain's right and left side have distinctly different ways of
looking at the world. Your two hemispheres are as different from each other
as me to you. The left brain controls the right side of the body (the
exception to this occurs with left handed people which is 15 percent of the
population) and is logical scientific, judgmental and verbal. It's
interested in the facts, and efficiency. The right brain controls the left
side of the body and deals with the creativity and imagination. It is
concerned more with the visual and emotional side of life.
As you read, your left-side is sensibly making connections and analyzing the
meaning of the words, the grammar and other complex relation-ships while
putting it into a "language" you can understand. Meanwhile, the right side
is providing emotional and even humerous cues, by looking at visual
information and causing you to find humor or sadness.
There are four lobes of the brain which divide the brain further. The four
lobes are frontal, pariental, occipital, and temporal lobes. Each one
fulfils a specific purpose. The frontal lobe deals with the motor skills,
planning, and personality it makes you move and even speak. The pariental
lobe is in charge of spatial organization of attention and body sensation.
The occipital lobe is the one that uses visual images it discerns them and
process them. The Temporal lobe is your hearing and object recognition
canter it works with memory. All of these lobes work together in performing
every day functions such as thinking, planning, and problem solving. Some
might consider the cerebrum as another lobe. The cerebrum itself deals
with balance and motor coordination. This means it allows you to understand
what direction is up and down, and it also keeps your coordination in tune.
The brain is deeper than just the cortex though. The brain stem is a also
a major section of the brain. It is a lower region below the cerebral
cortex. The thalamus is another part of the brain below the cerebral cortex.
The thalamus is acts as a relay station for incoming stimuli from our
senses. The hypothalamus is located below the thalamus and it regulates our
internal organs and systems, such as blood pressure, digestion, and hormone
secretion through the pituitary gland. The pons, also in the lower region of
the brain, stores information on pain, temperature and touch. Medulla
oblongata (or just 'medulla'). It is responsible for the automatic control
of heart rate and respiration rate when they are not
under voluntary control, meaning they happen without us making them. The
corpus collosum is the part of the brain, which integrates
the left and right side providing a pathway for learning an memory to be
transported and used.
The brain is connected with the rest of your body through the spinal cord.
The spinal cord is a major pathway in which your brain sends messages to the
rest of your body. The brain can receive information through all senses.
The brain is a complex organ, which is still not fully understood it is
being learned about more and more.
