Abstract

A neuron is the most fundamental cell of the brain and generates electrical activity in order to communicate with other neurons or parts of the body. Magnetoencephalography (MEG) is the measurement of the magnetic fields generated by neural activity in the brain. The corresponding technique for the electric field is electroencephalography (EEG). EEG has a long history and the first findings were reported by Richard Caton in 1875 when he measured electrical activity in the brains of rabbits and monkeys. Berger was the first to record a human EEG (he also gave the technique its name) in 1929. Since these remarkable achievements, EEG has evolved to become an important tool and is widely used for both scientific and clinical purposes. In the clinic it is particularly important for characterization of epileptic seizures.
