应用高尔基、尼氏和束追踪技术对仓鸮耳蜗角状核（NA）进行了研究。NA在背外侧脑干中形成细胞柱，其部分地与耳蜗大细胞核（NM）重叠，并且在其喙侧和外侧。最高的最佳频率映射在外侧NA（NAl）中，中间在内侧NA（NAm）中，并且最低在足部区域（NAf）中。细胞密度遵循tonotopic轴，并随着最佳频率的降低而降低。NA包含四种主要的细胞类别：平面、辐射、垂直和平行。平面型和放射型根据其初级树突的数量进一步细分为双极型和多极型。平面神经元局限于一个issueband，而放射神经元的树突，可以延伸到整个issueband。垂直细胞有长的树突，垂直于等轴带。短突细胞数量最多，由于其短树突而被限制在一个等长带内。这四类神经元均投射到下丘和外侧丘系背核。J.

The cochlear nucleus angularis (NA) of the barn owl (Tyto alba) was analyzed using Golgi, Nissl, and tract tracing techniques. NA forms a column of cells in the dorsolateral brainstem that partly overlaps with, and is rostral and lateral to, the cochlear nucleus magnocellularis (NM). Highest best frequencies are mapped in lateral NA (NAl), intermediate in medial NA (NAm), and lowest in the foot region (NAf). Cell density followed the tonotopic axis and decreased with decreasing best frequency. NA contained four major cell classes: planar, radiate, vertical, and stubby. Planar and radiate classes were further subdivided into bipolar and multipolar types according to their number of primary dendrites. Planar neurons were confined to an isofrequency band, whereas radiate neurons had dendrites that could extend across an isofrequency band. Vertical cells had long dendrites oriented perpendicularly to isofrequency bands. Stubby cells were the most numerous and were confined to an isofrequency band because of their short dendrites. Neurons in each of these four classes projected to the inferior colliculus and dorsal nucleus of the lateral lemniscus. J. Comp. Neurol. 429:192–205, 2001. © 2000 Wiley‐Liss, Inc.
