15 cool facts about Brain

1.The Brain is the part of the body's nervous System.The Brain,spinal cord and nerves makes up our nervous system.
2.We use our brain 100%.Almost every part of the brain in active at some time. Only thing,we may not use our whole brain all at once,but we do use them fully.

3.Our brain creates connections or pathways between 100 billion of microscopic cells called Neurons.They are nerve cells that carry messages back and forth between our brain and body.

"When you sit in the same position for 15-30 minutes,may lost feeling in the feet with heavy foot unable to stand and pain".This is because nerves run through all your body and temporarily squash your nerves in that area.So the nerves in that area can't send messages back to the brain normally,and you feel a pain.Again when you stand up,the nerves are not compressed,pain last for seconds and your foot will comes to normal.

4.The brain stem is located at the base of the brain,connecting to the spinal cord.The brain stem controls the body's involuntary functions such as breathing,blood pressure and heart rate.

5.Left side of the brain controls the right side of the brain and right side of the brain controls the left side of the brain.Each side of the brain controls most functions on the opposite side of the body.

6.The pituitary gland is about the size of the pea.It is the gland which controls our growth, located inside of the brain.

7.If we have any headache or pain in the head,our brain can't feel any pain because it has no pain receptors.But rest of the head can feel the pain.

8.The cerebrum is the biggest part and it makes up most part of our brain.It handles movements,language and our sensory organs.So without the nervous system we can't walk,think or breathe.

9.The temporal lobe find on the sides of the lower part of the brain controls the memory and is the home to the brain's memory center.

10.The brain is the control center of our nervous system.Our brain controls everything we do(consciously or not).It is the command center of our body.

11.The typical brain weighs 1.4 kilograms(3 pounds).That's the weight of the average brain.

12.The cerebellum is the part of the brain that helps us to balance and be safe from falling down.

13.As we think emotions won't come from heart.Actually emotions(sad,happy,angry) come from 'amygdala'.

14.Cerebral cortex/gray matter is the brain's outer layer. It is responsible for complex brain functions, such as language and information processing.

15.The hypothalamus controls the temperature in our body like thermostat controlling the room temperature.

Going To Mars Could Damage The Brains Of Astronauts

According to lead researcher M. Kerry O’Banion in a press release, ”Galactic cosmic radiation poses a significant threat to future astronauts. The possibility that radiation exposure in space may give rise to health problems such as cancer has long been recognized. However, this study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease.”

As part of the study, the researchers exposed mice with known timeframes for developing Alzheimer’s to the type of low-level radiation that astronauts would be exposed to over time on a long space journey. The mice were then put through tests that measured their memory and cognitive ability. The mice that were exposed to radiation showed significant cognitive impairment.

The mice also showed physical signs of degradation. An examination of their brains showed differences in blood flow in their brain. Also, the mice exposed to radiation showed larger plaques of the type seen with Alzheimer’s patients.

“These findings clearly suggest that exposure to radiation in space has the potential to accelerate the development of Alzheimer’s disease,” said O’Banion. ”This is yet another factor that NASA, which is clearly concerned about the health risks to its astronauts, will need to take into account as it plans future missions.”

It’s not going to be an easy problem to solve, either. The radiation the researchers used in their testing is composed of highly charged iron particles, which are relatively common in space. Due to their size and energy, those particles can pass through the walls of a spaceship. Shielding from that radiation is no simple task.

“Because iron particles pack a bigger wallop it is extremely difficult from an engineering perspective to effectively shield against them,” said O’Banion. “One would have to essentially wrap a spacecraft in a six-foot block of lead or concrete.”
