【摘要】 回声定位蝙蝠由于其听觉系统的特殊性及重要性,可以反馈地调节后继所发声信号的声学特征。在中枢,这些反馈调节有很大一部分发生在脑干尤其是中脑,包括旁外侧丘系被盖区、中脑导水管周围灰质、臂旁核、中央听觉束核以及上丘等区域及核团,它们分别对回声定位声的不同方面进行了重要的调控。这种调控对蝙蝠的特殊捕食行为有着重要的生物学意义。更多还原

【Abstract】 For the particularity and importance in auditory system of echolocating bats, they can modulate the following vocal features in feedback way. In central nerve system, the feedback mostly occurs in brainstem especially the midbrain, including paralemniscal tegmental area, periaqueductal gray, parabrachial nucleus, nucleus of the central acoustic tract, superior colliculus and other areas or nucleus. They make prominent modulation in different aspects of echolocating vocality respectively. This modulation has crucial biological signification in specific prey behavior in echolocating bats.更多还原
