The neural correlates of positive and negative evoked potentials

The neural correlates of positive and negative evoked potentials 

Stohr et al. (1989) write about the neural correlates of positive and negative surface potentials. 

Because of the complexity of cerebral structures, it is hardly possible to draw conclusions from the polarity of evoked potentials to the basic generators. The excited area is negatively loaded because of the current of positive ions into the
