最近的研究表明，听觉皮质分离系统根据蝙蝠下丘中央核的听觉经验，调节和改进正在进行的信号处理，并重新组织频率图。然而，是否所有受皮质迷走神经影响的丘神经元都参与了这两种类型的调制，目前还没有确定。在这项研究中，我们证明了一组(51%)的丘神经元只参与正在进行的信号处理的皮质分离调制，而第二组(49%)的丘神经元既参与正在进行的信号处理的调制，也参与听觉系统的重组。
Recent studies show that the auditory corticofugal system modulates and improves ongoing signal processing and reorganizes frequency map according to auditory experience in the central nucleus of bat inferior colliculus. However, whether all corticofugally affected collicular neurons are involved in both types of modulation has not been determined. In this study, we demonstrate that one group (51%) of collicular neurons participates only in corticofugal modulation of ongoing signal processing, while a second group (49%) of collicular neurons participates in both modulation of ongoing signal processing and in reorganization of the auditory system.
