Facts About Our Brain
The brain performs an incredible number of tasks
- It controls body temperature, blood pressure, heart rate and breathing.
- It accepts a flood of information about the world around you from your various senses (seeing, hearing, smelling, tasting, touching, etc).
- It handles physical motion when walking, talking, standing or sitting.
- It lets you think, dream, reason and experience emotions.
- Brain imaging studies show that human feelings originate inside the brain.
- The human brain structure is almost fully developed by age 11, though some higher self-management brain functions continue to develop into the mid 20’s.
- The diameter of an individual brain neuron is 4 microns, meaning 30,000 could fit on the head of a pin.
- The human brain has 10 billion neurons, making it the most powerful learning tool in the world.
- Each single brain neuron has from 1,000 to 10,000 connections with other neurons, making up to 10 trillion neuron connections possible.
- Alcohol interferes with brain processes by weakening connections between neurons.
- The same part of the brain interprets both your physical and emotional pain.
- Stress over long periods can weaken the brain’s ability to learn and remember.
- A dog’s brain is 19 times smaller than a human adult brain; an elephant’s brain 4 to 5 times bigger than ours.
- An adult bottle-nosed dolphin’s brain is about the size of a human adult’s brain.
- The average adult’s brain weighs 3 to 4 lbs. but consumes 20% of the body’s supply of oxygen.
- Loss of oxygen for even 5 to 10 minutes can cause serious brain damage.
- Our brain requires 20% of the entire body’s blood flow.
- The human brain contains 400 miles of blood vessels.
- Brain imaging functional MRI equipment measures blood flow and provides a picture of brain activity during actual emotional experiences.
- There is no sense of pain within the brain itself. This allows neurosurgeons to probe areas of the brain while the patient is awake.
- A living brain is so soft you could cut it with a butter knife.
- Brain messages travel between neurons in just one thousandth of a second.
- Each time you have a new thought or memory, a new brain connection is made between two or more brain cells.
- Your brain generates up to 25 watts of power while you’re awake—enough to illuminate a light bulb.
