Interesting Facts About Brain

MasyaAllah, Here's An Interesting Fact about Brain.

Dimensions and size :
The average dimension or cross-sectional area of ​​the adult human brain is: 140 mm / 5.5 inches, with a length of 167 mm / 6.5 inches, and a height or width of 93 mm / 3.6 inches. The average weight of the human brain at birth is first about 350-400gram, and the average weight of the human brain in adulthood is about 1300-1400gram. When stretched / stretched, cerebral cortex in the human brain measuring about 0.23 square meters

Composition :
The human brain has the following composition: 77-78% water, 10-12% lipids, 8% protein, 1% carbohydrate, 2% organic soluble water, and 1% non-organic salt. Cerebellum in the human brain contains half of all neuron cell cells, although this cerebellum covers only 10% of the total brain. Cerebral Cortex is the largest part of the brain, which is about 85% of the total brain. Percentage of total cerebral cortex volume are: 41% frontal lobe, 22% temporal lobe, parietal lobe 19%, and occipital lobe 18%. There are nearly 100 billion neuron cells in the human brain, almost equal to the number of stars in the galaxy. The human left brain has 186 million more neuron cells than the right brain. 750-1000 milliliters, or about 3 cans of soda with our blood filled condition flowing to the brain every minute.

Time :
The human brain can survive or stay alive for 4 to 6 minutes without oxygen, but after that the cells will begin to die. The slowest time to exchange information between neurons is about 416 km / h, which is the slowest, how about the fastest? During early pregnancy, the growth rate of neurons is 250,000 neurons every minute.
