Brain Facts & Addiction


“Whatever the mind of man can conceive and believe, it can achieve.” – Napoleon Hill

The mind is the most powerful part of the body. The physical and psychological functions of the brain are tremendous and often unknown. The brains ability to perceive and infer is incredible and unlike many other species.

I share this information as addiction to some substances destroy the brains ability to function properly. Addiction involves craving for something intensely, loss of control over its use, and continuing involvement with it despite adverse consequences.
Addiction changes the brain, first by subverting the way it registers pleasure and then by corrupting other normal drives such as learning and motivation. Although breaking an addiction is tough, it can be done. Brain damage is lifelong and currently irreversible. This is why it’s important to understand how the brain works, it’s facts and functions.

Brain Facts:
Brain Uses 20% of Blood
Approximately 20% of the blood flowing from the heart is pumped to the brain. The brain needs constant blood flow in order to keep up with the heavy metabolic demands of the neurons. Brain imaging techniques such as functional magnetic resonance imaging (fMRI) rely on this relationship between neural activity and blood flow to produce images of deduced brain activity.

Brain Uses 20% of Oxygen Breathed
Although the brain accounts for only 2% of the whole body’s mass, it uses 20% of all the oxygen we breathe. A continuous supply of oxygen is necessary for survival. A loss of oxygen for 10 minutes can result in significant neural damage.

Weight. The weight of the human brain is about 3 lbs.
Cerebrum. The cerebrum is the largest part of the brain and makes up 85% of the brain’s weight.
Skin. Your skin weighs twice as much as your brain.
Gray matter. The brain’s gray matter is made up of neurons, which gather and transmit signals.
White matter. The white matter is made up of dendrites and axons, which create the network by which neurons send their signals.
Gray and white. Your brain is 60% white matter and 40% gray matter.
Water. The brain is made up of about 75% water.
Neurons. Your brain consists of about 100 billion neurons.
Synapses. There are anywhere from 1,000 to 10,000 synapses for each neuron.
No pain. There are no pain receptors in the brain, so the brain can feel no pain.
Largest brain. While an elephant’s brain is physically larger than a human brain, the human brain is 2% of total body weight (compared to 0.15% of an elephant’s brain), meaning humans have the largest brain to body size.
Blood vessels. There are 100,000 miles of blood vessels in the brain.
Fat. The human brain is the fattest organ in the body and may consists of at least 60% fat.
Tickles. You can’t tickle yourself because your brain distinguished between unexpected external touch and your own touch.
Imaginary playmates. A study from Australia showed that children with imaginary playmates between the ages of 3 and 9 tended to be first-born children.
Reading faces. Without any words, you may be able to determine if someone is in a good mood, is feeling sad, or is angry just by reading the face. A small area in the brain called the amygdala is responsible for your ability to read someone else’s face for clues to how they are feeling.
Ringing in the ears. For years, medical professionals believed that tinnitus was due to a function within the mechanics of the ear, but newer evidence shows that it is actually a function of the brain.
Pain and gender. Scientists have discovered that men and women’s brains react differently to pain, which explains why they may perceive or discuss pain differently.
Supertasters. There is a class of people known as supertasters who not only have more taste buds on the tongue, but whose brain is more sensitive to the tastes of foods and drinks. In fact, they can detect some flavors that others cannot.
Cold. Some people are much more sensitive to cold and actually feel pain associated with cold. Research as shown that the reason is due to certain channels that send cold information to the brain.
Decision-making. Women tend to take longer to make a decision, but are more likely to stick with the decision, compared to men, who are more likely to change their mind after making a decision.
Exercise. Some studies indicate that while some people are naturally more active, others are naturally more inactive, which may explain why getting out and exercising is more difficult for some.
Boredom. Boredom is brought on by a lack of change of stimulation, is largely a function of perception, and is connected to the innate curiosity found in humans.
Physical illness. The connection between body and mind is a strong one. One estimate is that between 50-70% of visits to the doctor for physical ailments are attributed to psychological factors.
Sadness and shopping. Researchers have discovered that those experiencing the blues are more willing to spend more money in an attempt to alleviate their sadness.
