The electrophysiological audiogram of the Guinea fowl has been obtained using auditory evoked potentials from the MLD of unanesthetized birds. In restricted regions of MLD, phase-coupled responses to extreme low-frequency sinusoids (2-10 Hz) could be recorded at moderate intensities. The tonotopy of MLD extends continuously to the infrasound region at the rostrodorsal margin. Single-cell recording of infrasound responses show phase-locked firing of neurons with different phase delays for different cells.
通过未麻醉鸟类中脑外侧丘系（MLD）的听觉诱发电位，获得了珍珠鸡的电生理听力图。在MLD的特定区域，可以在中等强度下记录到对极低频正弦波（2-10赫兹）的相位耦合反应。MLD的音频定位在嘴背侧边缘连续延伸至次声区域。次声反应的单细胞记录显示，不同细胞的神经元具有不同的相位延迟，呈锁相放电。
