Potentiation of the habituation of human brain potentials.
A single-trial analysis, using the cross-covariance function to locate and quantify individual visual evoked potentials (VEPs), is employed to assess run-by-run changes in the habituation function of the N1-P2 wave of the vertex VEP. The characteristic exponential form of this function is shown to be less pronounced later in the experimental session. This finding is adduced as evidence of potentiation of VEP habituation and as such is argued to provide further justification for considering VEP habituation as genuine habituation in Thompson and Spencer's (1966) system.
