An EEG electrode on the scalp measures concerted PSPs of a large group of pyramidal neurons that result from active synapses (which arise due to APs from afferent neurons). The PSPs make the more superficial extracellular space negative compared to the deeper extracellular space.

... is, the neurons have to be aligned perpendicularly to the scalp (again, so that the summed activities does not cancel). This is shown in figure 7. Most cells that match this requirement are pyramidal cells (named after the characteristic shape of the cell body, as is visible in figure 7). ...
