- EEG and field potentials are created by the fluctuating currents of masses
- of neurons, the dendritic current arises in connection with the spike
- initiating zone on the neuron. In populations of neurons, especially
- those lined up in parallel, a summation effect is produced, which can
- be measured at the surface of the brain, the scalp, or with deep electrodes
- implanted directly in the cortex. Every electric field has its associated
- magnetic field, but it is not clear if either of these has a functional
- role. Some people refer to these as just the "noise" generated by the
- neural masses, which are helpful to us in trying to decipher what is
- going on in neural processing.
-
- I do not have them handy, but there are several references by Walter
- Freeman which explain the formation of EEG from masses of neurons.
