How our Brain Works.

The brain works in different ways and even though it is one whole organ it has different parts that make it seem like it has more.

1. What does the word "hemisphere" refer to when talking about the brain?
-This means the the brain is divided into 2 equal pieces (like the hemispheres on earth) and also can be used to say that the brain is actually two parts connected.

2. What are the major differences between the left and right sides of the brain?
-They control the opposide side they are on, personality is developed depending on how much do you have from each side.

3. What is the corpus callasum?
- The corpus collasum (from latin "corpus"=body and "callasum"= thought) is a flat bundle of neural fiber that unites the right hemisphere to the left hemisphere of the brain.

4. Explain the study performed by Paul Broca in which he discovered "Broca's Area."
- Paul Broca had two patients in which he discovered their problems. One was Lebronge a man that had damage on the left part of the frontal lobe and could only say one "word and it was "tan" which meant that his speech ability was reduced. The other was Lelong which had similar problems but could say five words: "yes", "no", "three", "always", and a mispronunciation of his name, "lelo". He was also damaged in the same part of the brain as Lebronge so this part was called Broca´s area and it is the part that controls speech and the processing of words,

5. Explain the study conducted by Roger Sperry in regard to "split brain."
- Roger and other scientists had studied many patients like one they named J.W. he had a seizure when he was 16 and throuhout the yeas he started to get epillectic attacks and they dicovered that it was caused by a damaged corpus callosum. This damage caun cause disorder in your brain and that is what causes epilepsy.

6. Explain the study conducted by Karl Wernicke which led to the discovery of Wernicke's Area."
-Wernicke thought that bot only Broca´s area was responsible for language preoblems so he deided he would study a bit of it so after alot of reasearch he found that he was right the area that is a little bit to the right of Broca´s area is also responsible for speech, this beaing true because the two are from the frontal lobe.

7. Which lobe is most responsible for vision?
- It is the optical lobe which analyzes what your eyes see.

8. Which lobe is most responsible for hearing and language?
- It is the temporal lobe, and it decodifies the language for you.

9. Which lobe is most responsible for performing math calculations?
- The Parietal lobe.

10. Which lobe is most responsible for judgment, reasoning and impulse control?
- The Frontal lobe, which also controlls the mood and personality.

We can see that the brain works in independent ways and that because of that we are what we are now. Without that it would be different.
