The corpus striatum were systematically explored by recording averaged potentials elicited by stimulation of the brachial plexus and sciatic nerve in 53 pigeons. It was found that the projection areas of brachial afferents were located within the neostriatum, the hyperstriatum and the ectostriatum. The sciatic projection areas overlap with the brachial projection areas in the neostriatum and a part of the hyperstriatum. Moreover, the brachial and sciatic projection are as in the striatum receive the inputs from both sides of the body. We suggest that the somatic projection areas of fore- and hindlimb are distributed diffusely in the striatum of the pigeon. That the projection area of forelimb is relatively larger is probably related with functional differentiation of the forelimb. Furthermore, the convergence of afferent impulses originating in the different regions of the body within the same brain area may be important for the integration of limb activities in pigeon.
通过记录53只鸽子臂丛神经和坐骨神经刺激诱发的平均电位，对纹状体进行了系统研究。发现臂部传入神经的投射区域位于新纹状体、上纹状体和外纹状体。坐骨神经的投射区域与新纹状体和部分上纹状体中的臂部投射区域重叠。此外，纹状体中的臂部和坐骨神经投射区域接受来自身体两侧的输入。我们认为，前肢和后肢的躯体投射区域在鸽子的纹状体中呈弥散分布。前肢投射区域相对较大可能与前肢的功能分化有关。此外，来自身体不同区域的传入冲动在同一脑区的汇聚可能对鸽子肢体活动的整合很重要。
