A network of nearly 100 billion individual cells called neurons or nerve cells, allows the brain to think, remember, hear a symphony, enjoy a sunset, love and imagine. Neurons tell our bodies to move, breathe and create.
The amazing network of neurons that forms the human brain makes it the most complicated brain on the planet. The complexity of the brain, not its size, accounts for its capacity. Dolphins, whales and elephants have larger brains, though in proportion to our body size, ours is the largest. Among humans it appears that brain size doesn't affect intelligence. 句法：that forms the human brain是定语从句修饰network 短语：make sth./sb. sth. 使……成为…… 词组：account for .
