Our bodily functions are governed by our nervous system, which consists of many nerve cells with extensions, or nerve fibers, which form a system of connections between the brain and spinal cord and the rest of the body. Signals in the nervous system are transferred by small electrical currents and by chemical substances. Edgar Adrian developed methods for measuring electrical signals in the nervous system, and in 1928 he found that these always have a certain size. More intensive stimuli do not result in stronger signals, but rather signals that are sent more often and through more nerve fibers.
