The human brain is an incredibly complex organ that controls every body function. It is made up of approximately 100 billion nerve cells, or neurons, which communicate with each other through electrochemical signals. These neurons are connected through an intricate network of synapses and are organized into regions specializing in different functions, such as memory, movement, and perception. The sheer number of neurons in the brain allows us to perform complex tasks such as problem-solving, language processing, and decision-making. |
