Summary

The scalp electroencephalogram (EEG) signals detect the extracellular electrical field generated by the columns underneath the electrodes closer to the cortical surface and represent near-synchronous summated potentials (excitatory postsynaptic potential (EPSP) and inhibitory postsynaptic potential (IPSP)) generated by these columns of the cerebral cortex.14
