Slow vertex response (SVR) has been applied for the objective audiological examination of infants. However, there are unsolved problems concerning the modality of SVR. Especially the generator of SVR has not clearly been defined.
The purpose of this study is to investigate the generator of so called “auditory evoked cortical response” in animal experiments.
Evoked potentials were recorded between the vertex and the ear lobe.
The conclusions were as follows:
1. SVR in cats revealed similar modality to that of human subjects.
2. P2 and N2 components were greatly influenced by anesthetics.
3. Bilateral primary auditory cortex were closely related to the generator of P2 and N2 components.
4. P1 and N1 components were mainly produced at the subcortical area including the brain stem.
