Starting To Understand Neuroscience
Neuroscience is the very interesting science behind the nervous system and one of the most
fabulous tools that we have, our brain. There are three main parts of neuroscience. The
central nervous system, the peripheral nervous system and the endocrine system are the
three main parts of neuroscience. Obviously, you can classify the brain and neuroscience in
many different ways as our understanding of the mind is still very limited. We are
discovering everyday exciting things about our abilities and how they play out in the brain.
The central nervous system includes the brain and spinal cord. You brain with the help of
the nervous system controls all of your body and organs and makes everything do the job it
is supposed to. The brain communicated with the rest of the body throughout the spinal
cord and the nerve system. Your spinal cord is a thick bundle of nerves that carries
information throughout the body for the brain.
The peripheral nervous system is made up of nerve
cells or neurons that are wired together through the
body like a communication system. Neurons carry
messages around th body in the form of electrical
and chemical impulses. Unlike other body tissues
neurons have a limited ability to repair themselves.
Over time if your brain loses neurons they are
usually never replaced in your body. Still, because
of neurogenesis, depending what do you do with
your brain and how often you challenge it, you
could start to re-create new neurons. This is part of
what we is called brain plasticity, or the capacity of
the mind to rewire itself.
The endocrine system works with the brain and nerves to keep the body functioning. It
controls how we grow, our feelings, our hunger and temperature. The endocrine system
also controls our hormones. All three of these parts of the nervous system are studied in
neuroscience as well as other specific diseases and disorders that affect the brain and
In the past neuroscience was a part of biology. However over time it has become an
interdisciplinary science that coordinates with other fields such as chemistry, computer
science, engineering, mathematics and psychology. Neuroscience uses several different
approaches to study the nervous system. It can be studied on a molecular, cellular,
developmental, structural or functional level.
The history of neuroscience dates back to ancient Egypt. Manuscripts dating back to as far
as 1700 BC show that the ancient Egyptians understood the concept of brain damage even
if there understanding was elementary compared to our knowledge today. Studies of the
brain and neuroscience became much more sophisticated after the invention of the
There are several important neuroscience organizations in the United States and abroad.
Some of the most prominent include The International Brain Research Organization, The
International Society for Neurochemistry and the Society for Neuroscience. Through
advancement of individual doctors and collaboration the world of neuroscience has become
very advanced in the last 20-30 years. We are learning so much about the nervous system
and the important functions it handles in our bodies.
