Abstract and Keywords
Preparing a movement or waiting for a stimulus that will show up in a few seconds is accompanied by a slow negative wave in the electroencephalogram (EEG). It is the result of a summation of a large number of postsynaptic potentials (EPSPs) in the cell columns of the cortical brain areas that will—in one way or another—be involved in the processing of the future event. Three different types of anticipatory slow waves can be distinguished based on the experimental context in which they can be elicited: the Bereitschaftspotential (BP), the contingent negative variation (CNV), and the stimulus-preceding negativity (SPN). This chapter discusses these potentials in detail. First, it considers which components might be distinguished and which brain areas might be involved in their emergence. It then answers the question of which neurotransmitter systems underlie their appearance and what functions they might have.
