Explanation:
Detailed explanation-1: -The brain is a mosaic made up of different cell types, each with their own unique properties. The most common brain cells are neurons and non-neuron cells called glia. The average adult human brain contains approximately 100 billion neurons, and just as many-if not more-glia.
Detailed explanation-2: -The human brain has often been viewed as outstanding among mammalian brains: the most cognitively able, the largest-than-expected from body size, endowed with an overdeveloped cerebral cortex that represents over 80% of brain mass, and purportedly containing 100 billion neurons and 10× more glial cells.
Detailed explanation-3: -The human brain contains about 100 billion neurons.
