How the Brain Works






The Sentis Brain Animation Series takes you on a tour of the brain through a series of short and sharp animations.This first in the series introduces you to the most fascinating part of your body - The Brain.


The brain is the most fascinating part of the human body. Not much to look at. It resembles a spongy massive tissue, feels like tofu and weighs roughly four tubs of butter. Our brain is actually made up of mostly water and about 10% fats. While our brain only makes up approximately 2% of the entire body's weight, it uses a massive 20% of 

the body's energy.

The brain's basic building blocks are known as neurons, and we have around 100 billion of these each with between 1000 to 10,000 connections to other neurons creating neural pathways or roads within the brain. There are literally trillions of neural connections within the brain, similar to a city's electrical power grid.
