When we think of the word “brain”, we all recall our mental concept about this organ, that looks like a large, rubbery, grey, mass, that is heavy and sturdy in shape.
However, the truth is that the human brain looks much different than this belief, based on the concept of a ‘fixed’ brain, or, a brain chemically treated to maintain the integrity of its shape.
The video by Dr. Suzanne Stensaas of the University of Utah reveals the unfixed shape of the human brain, and its structure and texture are definitely surprising!
Moreover, the brain is an incredibly interesting organ, and we know too little about it. Here are some facts that will surprise you:
-It weighs 3 pounds and is 5 inches long
-It has billions of nerve fibers and around 86 billion neurons, and they can be of more than 10,000 types
-In early pregnancy, the neurons develop at an alarming rate of 250,000 per minute.
-It is divided into two hemispheres, which are not identical
-- Eric Holland, a neurosurgeon and cancer biologist at the Fred Hutchinson Cancer Research Center and the University of Washington, says: “The more complicated a brain gets, the more gyri and sulci, or wiggly hills and valleys, it has”
-It is about 73% water, and 63% of the ‘dry’ mass is fat
-Researchers believe that we start forgetting things as we grow older due to the fact that the brain cannot filter and delete old memories, and this prevents the absorption of new ideas and things.
-The role of the frontal area of the brain is to support complex thought, to improve the skins of planning and organizing, and understand abstract concepts
-Even though different activities use different series of neurons, we are actually using the whole brain, not just 10% of its capacity
-The brain gets about 20% of the total oxygen and blood produced in the body.
-The brain starts losing consciousness only about 8-10 seconds after the supply of blood stops
-This organ will manage to survive for 5 to 6 minutes only in case it doesn’t get oxygen after which it dies.
-The brain will start using brain cells as a last resort to survive in case of restrictive diets and deficiency of energy and nutrients.
Isn’t our brain simply amazing?
