To the ancient Egyptians, the heart was the centre of mental activity – the brain was unimportant. However, over the centuries the relationship between the brain and though, language, and the senses has been revealed. The human brain is built around nerve cells called neurons from which Neurology gets its name. There are billions of neurons and they are in constant communication with other nerve cells. The brain deals not only with reasoning and language but also with autonomic functions (such as sweating and breathing that are not under conscious control). It also processes emotions and generates hormones.
