How Many Neurons in Human Brain Matter?
How many neurons in the human brain actually make up the entire mass of the human brain? Well, as a matter of fact, the answer is not that known. However, scientists have a pretty good idea what the number of neurons are, but they really do not know how they are organized. There is much debate over exactly how the brain works and how the connections among the neurons work. Even though there are very good theories that explain the processes of the brain, the actual answers remain somewhat elusive.
How many neurons in the human brain? Some research has shown that the average human brain has somewhere between one and two billion neurons. This is close to the number of neurons that exist in the mouse brain, which has about six hundred million neurons.
The question is, how many neurons are present in each particular part of the human brain? For example, the cerebral cortex, which is the part of the brain that controls speech and movement, contains around one hundred million neurons. The lateral cortex, which is the part that deals with visual tasks, contains another hundred million neurons. Another hundred million neurons can be found in the inferior system, which helps us understand how our body functions. These numbers, when put together, give us a staggering number of neurons in the human brain.
Now, how many of these neurons are actively producing myelin, which is the stuff that wires the neurons? Well, it seems that the cortex and the lateral cortex both have a fairly constant supply of new neurons, while the inferior system is constantly generating new connections. Therefore, the answer to the question of how many neurons in the human brain are being used is “a lot”. Not only are they being used at a high rate, but they are being produced at an incredibly rapid rate too. As you may imagine, this means that the number of people on this planet using their brains in some way is pretty high.
As you were learning about how the human brain works, you probably learned that our memories can’t be erased, only changed. If you’re like most people, you probably also learned that information can only be learned by experience. In other words, if you have a great aunt who lived two hundred years ago, you can never ask her how many neurons in the brain she used, because you don’t know. However, scientists have figured out how to measure this so that you can figure out just how much she retained.
How many neurons in the human brain matter much to you? As an intelligent and educated person, this is not the question that should never be asked. The real question is, how many neurons do you want to live long and healthy life? And what does your future hold for you? How will you deal with Alzheimer’s disease?
