Intramodal and interaural interactions of the human slow auditory evoked potential.
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.
