Over a Kilo of Special Gray Matter, Interesting Facts About the Brain

Your brain, consisting of billions of neurons (or nerve cells) that communicate with trillions of connections (synapses), is one of the most complex and fascinating organs of your body. Keeping your brain active and healthy is therefore of vital importance. Discover how powerful your grey matter is, on the basis of these interesting facts.

Sixty percent of the human brain consists of fat. This makes your brain the fattest organ in the body, with these fatty acids directly responsible for the performance of your brain. So make sure you feed it with appropriate, healthy foods.

Your brain is in development until you are twenty-five years old. Neurological development starts at the back of the brain and works its way forward. That is why the frontal lobes, which control the planning and reasoning, are the last ones to strengthen structure and connections.

The storage capacity of your brain is considered unlimited. Research seems to show that the human brain consists of approximately 86 billion neurons. Each neuron forms a connection with other neurons, so there can be up to 1 billion (1,000 trillion) connections. Over time, these neurons can combine, increasing storage capacity. In Alzheimer’s disease, however, many neurons are damaged and stop functioning, which particularly affects memories.

A piece of brain as big as a grain of sand contains about 100,000 neurons and 1 billion synapses. However, damage to neurons can have a major impact. During a stroke, for example, the blood is unable to transport oxygen to the brain. The result is that brain cells can die off and a certain part of the brain is lost.

Information in the brain travels at an impressive 430 km/hour. When a neuron is stimulated, it generates an electrical impulse that travels from cell to cell. An interruption in this standard operation can cause an epileptic seizure.

Our vertebra stops growing when we are 4 years old. This vertebra consists of both nerve cells and supporting cells and is responsible for spreading messages from your brain to your body. The spine is the main source of communication between the body and the brain. The disease ALS causes death of neurons in the brain and in the spinal vertebra, which sabotages the control of muscles.

It is a myth that only 10% of your brain is used. You use your brain completely. Neurologists confirm that your brain is fully active all the time.

A so-called ‘brain freeze’ by eating cold food is the pain caused by the cold coming into contact with the sensors in the outer layer of the brain, the meninges. As a reaction to the cold, the bloodstream contracts, causing a rapidly rising headache.

The human brain generates about 23 watts of current (enough to light up a light bulb). All that energy consumption requires for sufficient rest. Sleeping helps to keep the pathways through the brain healthy. Moreover, a lack of sleep stimulates the production of proteins associated with Alzheimer’s disease.

The human brain weighs about 1.2 to 1.3 kilograms. The weight has absolutely nothing to do with intelligence. Men usually have a slightly heavier cranium than women. Because the brain is a complicated organ that makes your life possible, you need to take good care of it!
