我们测试了下降投射在听觉加工和听觉运动整合中的作用。对分离的脑组织进行细胞内记录，对刺穿的神经元进行染色。听觉神经元响应纹状体和/或丘脑背侧的电刺激，它们整合前脑和听觉神经输入。高频刺激纹状体或丘脑改变了层状亚核环面神经元的听觉反应。我们的结果表明，层流核是前脑投影的主要目标，这为声引导行为的调制提供了基础。
We tested the role of descending projections for auditory processing and audiomotor integration in the anuran torus semicircularis. Intracellular recordings were made from isolated brain preparations, impaled neurons were stained. Auditory neurons responded to electrical stimulation of striatum and/or dorsal thalamus, they integrated forebrain and auditory nerve inputs. High frequency stimulation in striatum or thalamus changed the auditory response of torus neurons located in the laminar subnucleus. Our results suggest that the laminar nucleus is the primary target of forebrain projections, which provides a basis for modulation of acoustically guided behaviour.
