The origin of the different BSP waves is open to discussion. In this work we analyze the response curves with surface and intranuclear electrodes in cats, both before and after inducing electrolytic lesions in acute and chronic phase, in order to study the subsequent alterations. We found that waves whose origins are attributed to specific regions of the acoustic pathway when carried out with surface electrodes, fail to correspond with the results obtained by intranuclear electrodes. On the other hand, although the lesions to the lowest part of the acoustic pathway (cochlear nuclei) cause important alterations in the recordings, these alterations become smaller as the lesions are induced higher up the pathway. Thus, we believe that the origin of the different BSP waves is due to the sum of potentials of different zones of neuron activation, and not to specific locations of the acoustic pathway; this is more evident in the delayed waves.
不同BSP波的起源尚有待探讨。在这项研究中，我们分析了猫在急性期和慢性期诱导电解损伤前后，使用表面电极和核内电极记录的反应曲线，以研究随后的变化。我们发现，使用表面电极进行测量时，其起源归因于听觉通路特定区域的波，与核内电极获得的结果不一致。另一方面，尽管听觉通路最低部分（耳蜗核）的损伤会导致记录出现重要变化，但随着损伤在通路中位置升高，这些变化会变小。因此，我们认为不同BSP波的起源是由于神经元激活不同区域电位的总和，而非听觉通路的特定位置；这在延迟波中更为明显。
