在上橄榄复合体和外侧丘系腹侧核的单个听觉单位中检查了对声音的反应特性。单位分为十个“班级”；四个类别由单一属性（尖峰波形或对声音爆发的响应时间）定义，其余六个类别由哪只耳朵兴奋或抑制单元定义。单元还根据它们响应声音突发而产生的刺激后时间直方图的类型进行划分，并根据尖峰间间隔直方图的形状单独划分。后两个分组彼此之间以及与单元类别高度相关，并被组合成一个称为“射击模式类型”的单一分类方案。单元根据其调谐曲线的形状分为六组；还提供了调谐曲线带宽的数据。数据显示了自发放电率、最佳频率音调的阈值以及响应延迟......
Response properties to sounds were examined in single auditory units in the superior olivary complex and the ventral nucleus of the lateral lemniscus. Units were divided into ten ‘classes’; four classes were defined by single properties (spike waveshape or the timing of responses to sound bursts) and the remaining six classes were defined by which ear excited or inhibited the units. Units were also divided according to the types of poststimulus-time histograms they produced in response to sound bursts, and they were separately divided according to the shape of their inter-spike interval histograms. These latter two groupings were highly correlated with each other and with unit class, and were combined into a single classification scheme called ‘firing-pattern type’.Units were divided into six groups based on the shapes of their tuning curves; data on the bandwidths of tuning curves are also presented. Data are presented on spontaneous firing rate, thresholds to best-frequency tones, and latency of respons...
