A guided tour of the brain
The brain is an organ that serves as the center of the nervous system for most living things. There are only a few animals that do not have a brain like starfish or jellyfish. The brain is located in the head. It receives messages from other organs. The brain is the most complex organ. In a human, the cerebral cortex has more than a billion neurons. Each of these neurons are connected by synapses. These synapses are connected to several thousand other neurons. Neurons communicate with one another by sending messages through long fibers called axons. These axons send messages by sending pulses out. The function of the brain is to have control over the other organs of the body. Some basic types of responsiveness such
