Detailed explanation-1: -For half a century, neuroscientists thought the human brain contained 100 billion nerve cells. But when neuroscientist Suzana Herculano-Houzel devised a new way to count brain cells, she came up with a different number-86 billion.
Detailed explanation-2: -Remarkably, at an average of 86 billion neurons and 85 billion nonneuronal cells (25), the human brain has just as many neurons as would be expected of a generic primate brain of its size and the same overall 1:1 nonneuronal/neuronal ratio as other primates (26).
Detailed explanation-3: -The human brain is the most complicated organ that nature has ever created: 100 billion nerve cells and many more contact points between them provide our brain with capabilities that no supercomputer can match to this day. One of its most important characteristics is its ability to learn.
Detailed explanation-4: -The nervous system is composed of more than 100 billion cells known as neurons. A neuron is a cell in the nervous system whose function it is to receive and transmit information.
