The human brain differs considerably from the brains of all other animals. It can be all kinds of things that are too difficult for animal brains or unthinkable. For example, talking, solving difficult questions (such as how the brain works) and making plans for the future. The main difference with animals is the ability that people have to share thoughts, emotions and ideas with others. a fantastic read
The functioning of the brain
The brains lie under the meninges and can be subdivided into the large brain, brain stem and cerebellum. The large brains are formed by two uniform brain halves that are interconnected by a beam. The large brains are connected to the brainstem by means of two stems.
The brain occupies only 2 percent of our body weight, but consumes as much as 20 percent of all the oxygen we absorb and even 30 percent of the energy we have at our disposal.
The big brain
Every part of the big brain can be divided into four parts:
The motor centers lie just in front of the central groove that distinguishes the frontal lobe of the lateral lobe. These motor centers provide the stimulation of for example the movement muscles in the opposite body half. So the motor part of the big brain on the left side controls the functions on the right side of the body.
Behind the central groove we find the centers that have the task of absorbing and processing the emotional stimuli. The centers for smell, taste, hearing and facial stimuli have a fixed place, just like the centers for speech and writing.
In the brain stem we find the largest central switching station for processing the incoming signals from the cerebral cortex. Here is also the control center for sexual function and sexual maturity.
Our brains are made up of about 100 billion neurons (nerve cells). The neurons are connected to each other. Each neuron can connect to about 5,000 other neurons. The connections are made through the foothills of the neurons, the dendrites. Not the number of neurons determines our thinking capacity, but more the number of dendrites. The dendrites can be made into old age. The information that we receive through our senses is processed via the short sensory memory and the short-term memory and is stripped of unnecessary information. Then this filtered information goes to the long-term memory. With the stored information we can make infinite performances. We call thinking about applying this available information.
The brain of Albert Einstein
Einstein actually had rather ordinary brains, but there was something special about it: the brain area responsible for mathematics and the sense of space and time was much more developed than normal. As a result, Einstein’s brains were 15% wider than the average person. Another special feature was that the groove in the middle of the brain stopped halfway. It is possible that more neurons were connected to each other and they worked better together.
