| What are the 5 Main Areas in the Brain called? | -Cerebrum
-Cerebellum
-Medulla
-Hypothalamus
-Pituitary |
| What does the Cerebrum do? | -This controls:
Intelligence
Personality
Conscious Though
High Level Functions [Language] |
| What does the Cerebellum do? | -This controls:
Balance
Co-ordination of Movement
Muscular Activity |
| What does the Medulla do? | -This Controls
Unconscious Activities [Breathing, Heart Rate] |
| What does the Hypothalamus do? | -This Controls
Temperature
Water Balance
Pituitary Gland [Controls what it Releases] |
| What does the Pituitary do? | -This does
Hormonal Production [Menstrual Cycle...] |
| What is Brain Function exactly? How much is known? | -This is saying how the Brain works. If you Experiment with Brain Function, your experimenting with how the Brain Works
-This field of Science is pretty vague, compared to other Fields |
| What was the most common way to find out Brain Function in History? Name an Example | -To study people with Brain Damage, as if part of a Brain is Damaged, and one of the Body's Stop Responding, a Link could be Established
-Example could be Paul Broca [1824-1880] He found out the Broca Area, which is all about Language. He did Experiments with people that had Speech Problems, and he found out All of them had Lesions on the Broca Area [Lesions are Wounds, tumors etc...]
-This was a Massive Discovery, which would open the door to this Science |
| How can Strokes happen? What can they Cause? | -Simply block Blood Flow to the Brain.
-Example can be that after a Stroke, people lost control of Muscles in One Side of the Body
-Others can be Vision Problems [Back part of the Brain] and Memory [Front Part of the Brain] |
| What is PET, how can it Help with the Brain | -PET is Positron Emission Tomography.
-Here, Water is given to the Brain that has Radioactive Oxygen.
-The Radioactive Water can give off Gama Rays, which can be Detected
-If a part of the Brain is Working, More Gama Rays will be seen. |
| Why is it Hard to study the Brain Function? | -People with Brain Damage won't live as long [Usually]
-People that have Brain Damage from Injury are Rare, and may not give Consent.
-People with Horrible Brain Damage may not even be able to Agree to it, meaning the Family has to choose. This is an Ethical Issue.
-The Brain functions in a Machine, could be Different Outside a Machine, and we would not know |
| Why can Treating Problems in the Brain be Hard? | The Brain can go wrong, in Many Ways
-Very Hard to repair the Nervous System. Neurones in the CNS don't Repair Fast, and no manmade way is made to Repair Neurones
-If a Problem happens in a Hard Accessible Part, Treating could be more Difficult.
-Treating can lead to Permanent Damage. [Surgery of Brain Tumor could lead to Parts of Brain being Damaged] |
| What are Symptoms of a Sever Head Injury | -Unconsciousness
-Concussion [Mental Function drops]
-Fits or Seizures
-Hard to Talk, See, Hear and Walk |
