Our brain keeps the body running all day long. The brain is part of the central nervous system and receive tons of information every microsecond, faster than any supercomputer built ever. Here are surprising brain facts you need to know.
Can you “see” through your ears?
Neuroplasticity, or the brain’s capacity to reorganize and adjust itself throughout a person’s lifetime, is a truly remarkable thing. A study in 2011, published in the Proceedings of the National Academy of Sciences, University of Montreal researchers compared the brain activity of persons who were born blind and those who had normal vision. What they found is actually amazing, the part of the brain that’s normally wired to work with our eyes can instead rewire itself to process sound information instead of visual perception.
Glial cells – The microscopic unsung heroes
Did you there are at least as many glial cells that support and protect the neurons in your brain? “These microscopic unsung heroes make sure neurons have a constant supply of nutrients and oxygen, insulate neurons from each other, and even help clean up after neural damage.
Brain scans “light up” when a person is in love
Love has the power to heal, functional brain scan reveals for people who are romantically in love, show activity where dopamine, the ‘feel-good’ neurotransmitter just lightens up. Fall in love and shine!
Strange –The visual areas of the brain are in the very back
The part of your brain responsible for vision, the occipital lobe, is located in the back. Tap a little hard someone on the back of the head and they will see stars, not sounds,” says Henry Soper, PhD, a former clinical psychology faculty member in the School of Psychology at Fielding Graduate University. Your left side of your brain controls the vision on your right side and vice versa. The same applies to how our brain processes sound—on opposite sides of the head.
Our brain is shrinking
Paleoanthropological research suggests that our brains are shrinking. Skeletal evidence backs up this theory. Some scientists also support the fact that this may be because the average body size of humans has also shrunk in size over the last 10,000 years. “A larger body requires a larger nervous system, so, as our bodies grew smaller, so did our brains in response,” suggests Donald Krieff, DO, a board-certified neurosurgeon.
The brain waves of two musicians can synchronize when performing together
It’s just not smartphones that can be paired. A team of scientists at the Max Planck Institute for Human Development in Berlin, Germany, used electrodes to record the brain waves of 16 pairs of guitarists as they played the matching musical sequence. Even though the two musicians in each pair played different parts, their brain waves synchronized. “This breakthrough study suggests that there’s a neural blueprint for coordinating actions with others.
Fat is intelligence
You read it correctly; the brain is the fattiest organ in your body, consisting of a minimum of 60 percent fat. And so the reason a diet rich in healthy fats, such as omega-3s and omega-6s, is essential for brain and overall body health. “Fat stabilizes the cell walls in the brain and carries, absorbs, and stores fat-soluble vitamins in your bloodstream,” explains Brock. “It also reduces inflammation and helps the immune system regulate and function properly.”
The brain is not permanently arranged at birth
Sometimes toddlers have to undergo extensive brain resections due to medical reasons and these events may, unfortunately, mean removing the primary language center in the brain,” tells Jennifer Bickel, MD, a pediatric neurologist and director of the Comprehensive Headache Clinic at Children’s Mercy Kansas City. However, if adults undergo a similar procedure, they are often unable to communicate through written or verbal language. A child’s brain is so flexible that it will reorganize itself and the ability to use language will be retained.
Your brain’s storage capacity is virtually unlimited
There’s no such thing as knowing too much—or learning so much that you can’t retain any more information (though it can certainly feel that way after sitting through a longboard meeting). “Your brain doesn’t get ‘used up’ like the data stored in your computer or smartphone,” says Dr. Krieff. “There is endless brainpower! Although lack of sleep can affect your brain’s ability to create more memories.”
Use your brain or lose it
The brain is like a muscle, explains you can build up your ‘cognitive reserve,’ or your brain’s innate ability to get a job done, through diverse types of learning and or through a new skill. People with a stronger and healthier cognitive reserve have been shown to be more gifted in coping with unpredicted life events.
Made up of billions of neurons (or nerve cells) that communicate in trillions of connections called synapses, our brain is one of the most complex and fascinating organs in your body. Keeping your brain healthy and active is vital.
