Components of VEP and AEP of 27 male hooded rats with chronically implanted electrodes in the anterior medial superior colliculus (CS) were measured and compared during relaxed wakefulness. Peak times of the VEP are correlated to the log of the quotient II/I of amplitudes P20-N32 (II) and P5-N10 (I) of AEP on the same recording point. The conclusion is drawn that the configuration of the collicular EP strongly depends on the distribution of neuronal elements around the electrode tip.
