The 80 billion neurons have between 1000 and 400,000 connections. The information is not located in the cells but in the connections. All brain cells are active and work together at the same time. Together they carry out tens of thousands of tasks simultaneously, without any central control and without us being aware of this. This gigantic network of networks of networks has no central decision maker. The most important central organ is a clock, our biological clock that synchronizes these trillions of interactions. It is a most beautiful example of what IT specialists call distributed computing, with a sophistication that is way beyond anything we can achieve with the most modern computers and computer networks, even the world wide ones.
Another superior feature of our brain is that it is amazingly fault tolerant. We can lose many cells through natural ageing or by accident, without impairing the whole system. This is possible because the brain continuously programs and reprograms itself, it wires and rewires itself, and it can change itself and heal itself, especially while we sleep. This is done all the time for individual cells or groups of cells and connections, but even big parts of the brain can take over the function of completely different parts. This way the normal losing of neurons with aging has no negative consequences. Such an amazing fault tolerance is still a faraway dream for computers, where one faulty transistor can wreck a computer chip.
