目的 研究鸣禽端脑古纹状体粗核（ＲＡ）壳区的神经联系。 方法 ＨＲＰ和生物素结合的葡聚糖胺（ＢＤＡ）的神经示踪技术。 结果 鸣禽古纹状体粗核壳区的传入纤维来自新纹状体听区Ｌ１、Ｌ３ 和高级发声中枢壳区（ＨＶＣ ｓｈｅｌｆ）；传出纤维投向间脑卵圆核壳（Ｏｖ ｓｈｅｌｌ）、中脑背外侧核与丘间核之间的界面区（ＭＬｄ／ＩＣｏｉｎｔｅｒｆａｃｅ）。鸣禽古纹状体粗核壳区与高级发声中枢壳区间与已报道的非鸣禽相应脑区一样存在喙－尾投射关系。 结论 鸣禽古纹状体粗核壳区及与其有联系的其他听觉－发声核团壳区可能具有多种生理功能。鸣禽壳区在进化上较为保守。
Objective To study the neural connections of the thalamic caudate nucleus (RA) shell of songbird. Methods Neurological tracing of HRP and biotin-conjugated dextran amine (BDA). Results The afferent fibers in the nucleus of the striatum of the striatum of striatum came from L1 and L3 of the auditory striatum and from the HVC shelf of the striatum, Midbrain dorsolateral nucleus and interlobular nucleus interface area (MLd / ICointerface). The striatus-caudal projection exists in the striatum of the striatum of the songbirds, which is similar to that of the corresponding brain regions of non-songbirds reported in the epicentrophic shell of the songbird. CONCLUSIONS: There are many physiological functions of the pterygocells of the striatum and other auditory-phonuclear nuclei associated with them. The shell of songbird is evolutionarily conservative.
