Summary

It is proved that the human slow auditory evoked potential (SAEP) possess intramodal (frequency) and interaural specific properties. It is shown that tonotopic and bilateral organization of the SAEP generating system is better expressed at lower stimulus intensities. It is concluded that neuron populations of the SAEP generating system which perceive less different tone stimuli overlap each other greater than those which perceive more different stimuli. The data on intramodal and interaural specificity of SAEP are discussed from the point of view of its extralemniscal origin.

Intramodal- und interauralspezifische Eigenschaften des SAEP beim Menschen

Zusammenfassung

Aus den Ergebnissen wird gefolgert, daß die SAEP intramodal- und interauralspezifische Eigenschaften besitzen. Es wird gezeigt, daß die tonotope und bilaterale Organisation des die SAEP erzeugenden Systems bei niedrigen Schallintensitäten besser ausgeprägt ist.

Die Ergebnisse demonstrieren, daß die Neuronenpopulationen des die SAEP erzeugenden Systems sich für die Perception gering unterschiedlicher Schallreize stärker überlappen, als diejenigen für die Perception unterschiedlicherer Schallreize.

Die Ergebnisse, die die intramodal- und interauralspezifischen Eigenschaften der SAEP charakterisieren, werden aus der Sicht ihres extralemniscalen Ursprungs diskutiert.
