Have you ever wondered what you're brain is really capable of? Well if you have this is the page for you. In this there will be 9 facts about your brain
When we think we’re multitasking, we’re actually context-switching. That is, we’re quickly switching back-and-forth between different tasks, other than doing them at the same time.
The book Brain Rules explains how harmful “multitasking” can be: Research shows your mistake rate goes up 50 percent and it takes you double the time to do things
The cerebrum makes up 85% of the brain’s weight, and the brain makes up about 2% of a human’s body weight. The texture of the brain is like a jelly. The heaviest normal human brain weighed 4.43 pounds. It belonged to the Russian Writer Ivan Turgenev. And the smallest brain, just 2.41 pounds, belonged to a woman.
This means that dehydration, even as small as 2%, can have a negative effect on brain functions. Dehydration and a loss of sodium and electrolytes can cause acute changes in memory and attention. To prevent any loss of body or brain function, take steps to keep your body properly hydrated.
A 2 year old baby will have an 80% grown brain. It will keep growing until you’re about 18 years old. It isn’t until about the age of 25 that the human brain reaches full size. The human brain is the largest brain of all vertebrates relative to body size.
Chemical activity in your brain, the nerves or blood vessels around your skull, or the muscles of your head and neck can play a role in most headaches. Serotonin is a chemical needed for talking between nerve cells. When serotonin or estrogen levels change, the result for some is a headache or migraine. Serotonin levels may affect both sexes, while changing estrogen levels affect women only.
This is about the same as the number of stars in the Milky Way galaxy. These neurons are connected by trillions of connections, or synapses. Experts call this a “neuron forest”. Information runs between these neurons in your brain for everything we see, think, or do. These neurons move information at different speeds. The fastest speed for information to pass between neurons is about 250 mph. That being said, neurons only make up 10% of the brain.
We actually use all of it. We’re even using more than 10 percent when we sleep. Although it’s true that at any given moment all of the brain’s regions are not concurrently firing, brain researchers using imaging technology have shown that, like the body’s muscles, most are active over a 24-hour period.
The brain has a higher cholesterol requirement than any other organ. In fact, about 25% of the body’s cholesterol stays within the brain. The brain is highly dependent on cholesterol, but its cholesterol metabolism is one of a king. Because the blood-brain barrier prevents brain cells from taking up cholesterol from the blood, the brain must make its own cholesterol. The brain’s cholesterol is much more stable than the cholesterol in other organs, but when it breaks down, it is recycled into new cholesterol right in the brain.
There are no pain nerves in the brain itself. But the meninges, periosteum , and the scalp all have pain nerves. Surgery can be done on the brain and technically the brain does not feel that pain.
