(You can roll your mouse over the picture of the brain above to find out more about the parts of the brain.). Neurons. Every part of the brainâand the rest of the nervous system, for that matterâcontain neurons (more than 100 billion of them in all). Neurons are nerve cells with some very special properties.
The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body.In a typical human, the cerebral cortex (the largest part) is estimated to contain 15â33 billion neurons, each connected by synapses to several thousand other neurons. The hippocampus, strictly speaking, is found only in mammals. 2  However, the area it derives from, the medial pallium, has counterparts in all vertebrates. 3  There is evidence that this part of the brain is involved in complex events such as spatial memory and navigation in fishes, birds, reptiles, and mammals.
