海豚的听觉神经科学主要集中在听觉脑干反应上，然而，这些措施揭示了海豚在回声定位和声学交流过程中的认知过程。以往对海豚中、长潜伏期脑诱发电位（AEPs）的研究报道了不同的潜伏期、极性和幅度。这些不一致可能是由于方法上的许多差异造成的，但这些研究没有说明哪些方法上的差异可能是造成差异的原因。本研究评估了电极放置和预处理方法如何影响（Tursiops truncatus）的中潜伏期和长潜伏期AEP。当参考电极放置在前额、外耳道或背鳍前的背表面上时，测量AEP。使用或不使用数字50 Hz低通滤波器对数据进行预处理，并使用独立分量分析将与神经过程相关的信号分量与其他信号隔离。结果表明，鼻道参考电极提供了最高质量的AEP信号的传感器空间的分析，而背参考产生的组件空间的名义上的改善。这些结果为测量海豚皮层AEP提供了指导，支持了未来对其认知听觉处理的研究。在线版补充材料可通过10.1007/s 00359 -021-01502-5获得。
Auditory neuroscience in dolphins has largely focused on auditory brainstem responses; however, such measures reveal little about the cognitive processes dolphins employ during echolocation and acoustic communication. The few previous studies of mid- and long-latency auditory-evoked potentials (AEPs) in dolphins report different latencies, polarities, and magnitudes. These inconsistencies may be due to any number of differences in methodology, but these studies do not make it clear which methodological differences may account for the disparities. The present study evaluates how electrode placement and pre-processing methods affect mid- and long-latency AEPs in (Tursiops truncatus). AEPs were measured when reference electrodes were placed on the skin surface over the forehead, the external auditory meatus, or the dorsal surface anterior to the dorsal fin. Data were pre-processed with or without a digital 50-Hz low-pass filter, and the use of independent component analysis to isolate signal components related to neural processes from other signals. Results suggest that a meatus reference electrode provides the highest quality AEP signals for analyses in sensor space, whereas a dorsal reference yielded nominal improvements in component space. These results provide guidance for measuring cortical AEPs in dolphins, supporting future studies of their cognitive auditory processing.
