5. Human brain isn’t the firm and is gray mass.
6. Living brain tissue is a squishy, pink and jelly like organ thanks to the loads of blood and high water content of the tissue.
7. Our brain is amazing. All scientific and technological achievements of human civilization come from the brain.
8. Getting a drink to keep human brain hydrated from dehydration feeling.

12. If stretched or stressed out the cerebral cortex would be 0.23 sq.m (2.5 sq.ft), the area of a night table.

Structure (Composition)
14. The composition of the brain is 77 to 78% water, 10 to 12% lipids, 8% protein, 1% carbs, 2% soluble organics, 1% inorganic salt.
15. The breakdown of intracranial contents by volume (1,700 ml, 100%): brain is 1,400 ml (80%); blood = 150 ml (10%); cerebrospinal fluid = 150 ml (10%).
16. The cerebral cortex is approximately 85% of the brain.
17. The cerebellum contains half of all the neurons in the brain but encompasses only 10% of the brain.
18. Percentage (%) of whole cerebral cortex volume = frontal lobe 41%, temporal lobe 22%, parietal lobe 19%, occipital lobe 18%.
19. Human brain contains approximately 100 billion neurons, the equal number of stars in our galaxy.
20. Brain left hemisphere consists 186 million more neurons than the right hemisphere.
21. 750-1000ml of blood flow through the brain every minute or about 3 full soda cans.
22. The brain will consume 46cm3 (1/5 cups) of oxygen from the blood in that minute.
23. The same oxygen consumed 6% by the brain's white substance and 94% by the grey substance.
Living Period / Duration
24. The brain could remain alive for about 4-6 minutes without oxygen. After this prescribed time cells or tissues of brain begin dying or failing.
25. The slowest speed of information traveling among neurons is 416 km/hour or 260 mph, that as "slow" as todays’ supercar's top speed (the Bugatti EB 16.4 Veyron clocked at 253 mph).
26. 10 seconds is the period of time until unconsciousness after the loss of blood supply to the brain.
27. Time until reflex loss after loss of blood supply to the brain is 40-110 seconds.
28. The rate of neuron growth during early pregnancy is about 250,000 neurons per minute.
Miscellaneous Infesting and Fun Facts About The Human Brain

31. The energy used by the human brain is enough to light a bulb of 25 watt.
32. More electrical impulses are generated in one day by a single human brain than by all the telephones in the world.
33. How much does human brain think? The number of thoughts is 70,000 approximately which the human brain produces on an average day.
34. After age 30, the brain shrinks a quarter of a percent (0.25%) in mass each year.
