How does our brain work?

"If the human brain were so simple that we could understand it, we would be so simple that we couldn't.”
~Emerson M. Pugh



Even with the stunning technology scientists own in the 21st century, the brain remains to be the most complex and mystifying machine known to humans.



What does each part of the brain do?
-The frontal lobe is a part of the cerebral cortex in the brain. This part of the brain effects our reasoning. planning, problem solving, emotions, parts of speech and movement.
-The second major division in the cerebral cortex is the parietal lobe. This part of the brain processes sensory information such as touch, temperature, or pain. Our thought process also takes place in this portion of the brain.
-The occipital lobe is the third major division in the cerebral cortex. It functions to process visual information.
-Lastly, there is the temporal lobe. This major division controls hearing, memory, and learning.
-The cerebellum helps us maintain balance and posture.
-The brain stem controls several basic actions. For instance, breathing, sleeping, eating, heart beat, and blood pressure.

Mysteries of the Mind
According to livescience these are the top 9 mysteries that perplex scientists about the brain.

1) Consciousness: Your consciouness is your awarness and the sensations or your surrounding. This simple act has become a brainteaser for scientists.
2)Deep Freeze: Scientists believe that the body and the brain can be thawed and revived in the future. However, so far this is not possible.
3) Why do humans age?
4)Are thoughts and personalities controlled by genes or the enviornment?
5)Why in the world to we laugh? (HAHA~ I never quite understood that either!)
6)Why are some memories hard to forget? (With research, scientists found out that the hippocampus is resposible for storing memory.)
7)How are "phantom feelings" caused? "Phantom limb" is an anomaly which causes one to feel warmth, pressure, itching, or pain due to a mssing limb. Scientists have two theories as to why this occurs; however, they are not sure.
8)Why do we sleep? Why is sleep a crucial aspect in life?
9)Why do we dream?
