在手术过程中暴露下丘时，记录下下丘的声诱发电位。对用90 dB的2000 Hz短纯音刺激的对侧刺激的最早反应是潜伏期为λ的正偏转。6.5 ms，随后是持续. apprx的缓慢的负偏转。这个表面阳性峰可能起源于外侧丘系。其潜伏期与从头皮记录的BSEP [脑干诱发电位]的第5顶点正波（V）相匹配。叠加在慢电位上的是几个峰。这些峰在通过过滤去除慢组分后清晰地出现。然后，这些峰具有与头皮记录的BSEP的峰VI、VII和VIII的峰宽相匹配的峰宽。
Sound-evoked potentials were recorded from the inferior colliculus in man when it was exposed during surgery. The earliest response to contralateral stimulation with 2000 Hz tone bursts at 90 dB was a positive deflection with a latency of .apprx. 6.5 ms that was followed by a slow, negative deflection that lasted .apprx. 5 ms. This surface-positive peak probably originates in the lateral lemniscus. Its latency matched that of the 5th vertex-positive wave (V) of the BSEP [brain stem evoked potential] recorded from the scalp. Superimposed on the slow potential were several peaks. These peaks emerged clearly after the slow components were removed by filtering. The peaks then had latencies that matched the latencies of peaks VI, VII and VIII of the scalp-recorded BSEP.
