The temporal neocortical afferent connections to the amygdala were investigated in the rhesus monkey using the silver impregnation and autoradiographic tracing methods. A large topographically organized projection to the amygdala was found to originate from the anterior superior temporal gyrus (area TA), the anterior middle and inferior temporal gyri (area TE), and the medial and lateral aspects of the temporal pole (area TG). These projections terminate in discrete adjacent regions of the lateral and basal amygdaloid nuclei. The temporal pole projection terminates in the ventral two thirds of the medial one half of the lateral nucleus and in the accessory basal nucleus, the anterior superior temporal gyrus projection terminates in the ventral two thirds of the lateral one half of the lateral nucleus, and the anterior middle and inferior temporal gyri projection terminates in the dorsal parts of the lateral and lateral basal nuclei. A projection from the perirhinal cortex to the medial basal nucleus of the amygdala is also discussed. Our findings reveal that a far greater proportion of the temporal neocortex than previously described contributes afferents to the amygdala, further strengthening the view that the amygdala occupies a key anatomical position linking the neocortex with diencephalic structures.
利用银浸染法和放射自显影示踪法，在恒河猴中研究了颞叶新皮质向杏仁核的传入连接。发现有一个按地形组织的向杏仁核的大量投射，起源于颞上回前部（TA区）、颞中回和颞下回前部（TE区）以及颞极的内侧和外侧（TG区）。这些投射终止于杏仁外侧核和基底核的离散相邻区域。颞极投射终止于外侧核内侧半部的腹侧三分之二以及副基底核，颞上回前部投射终止于外侧核外侧半部的腹侧三分之二，颞中回和颞下回前部投射终止于外侧核和外侧基底核的背侧部分。还讨论了嗅周皮质向杏仁核内侧基底核的投射。我们的研究结果表明，向杏仁核传入的颞叶新皮质比例比先前描述的要大得多，进一步强化了杏仁核在连接新皮质与间脑结构中占据关键解剖位置的观点。
