了解人类大脑的两个半球为什么以及如何形成 拥有明显不同程度的智力能力， 即“半球专业化”，这是一个具有挑战性的问题，具有广泛的 神经学和精神病学的进口。一个特别引人注目的例子是 这种专门化是右脑识别人脸的专门化， 根据汉密尔顿和Vermeire的工作，这是一种共享的设施 无论是猕猴还是人类。使用“分脑”猕猴，在这些猕猴中， 半球可以单独测试，建议的实验将使用 先进的成像和行为技术，努力确认 并扩展了以前的工作，并实现了更健壮的表达 这似乎是两个半球之间的内在差异。此外, 眼球运动将被记录和分析，以确定是否 半球的专门化体现在图像的图案上 收购。众所周知，切除颞叶，突出的是 包括杏仁核在内，猕猴的扫描眼睛会产生扰动 运动和视觉上明显无法识别刺激 通常会产生强烈的情绪反应，比如人类的存在。 这一点以及许多解剖学和生理学数据表明，杏仁核 可能在杏仁核内的面部识别中发挥作用 半球，以确定选择性效应是否可以在 识别各种类型的图像。实验也将是 以了解单侧大脑半球完整的杏仁核是否可以通过 大脑半球间通路，缓解损伤所致的虚弱 另一个半球的杏仁核。最后，电生理学， 实验将试图定义一种激活的假定差异 大脑半球在解决视觉助记问题，而不是 这个半球仅仅是“空闲”的。

Understanding why and how each of the two human cerebral hemispheres come to possess demonstrably different degrees of intellectual capability, i.e., "hemispheric specialization",' is a challenging problem, of wide import in neurology and psychiatry. A particularly striking example of such specialization is that of the right hemisphere in recognizing faces, a facility, according to the work of Hamilton and Vermeire, that is shared by macaques as well as man. Using "split-brain"macaques, in which each hemisphere can be tested individually, the proposed experiments will use sophisticated imaging and behavioral techniques in an effort to confirm and extend this prior work, and to achieve a more robust expression of this seemingly inherent difference between the hemispheres. In addition, eye movements will be recorded and analyzed to determine whether such hemispheric specialization is reflected in the patterns of image acquisition. It is known that removal of the temporal lobe, prominently including the amygdala, in macaques yields perturbation of scanning eye movements and a pronounced inability visually to recognize stimuli that normally produce a strong emotional response, such as the human presence. This, and much anatomical and physiological data suggest that the amygdala might play a role in facial recognition within the amygdala of one hemisphere to determine whether a selective effect can be demonstrated on recognition of various types of images. Experiments will also be undertaken to learn whether an intact amygdala in one hemisphere can, via interhemispheric pathways, alleviate the deficiency caused by damage to the amygdala in the other hemisphere. Finally, electrophysiological, experiments will seek to define presumed differences in activation of a hemisphere that is "working" on visual mnemonic problems versus a hemisphere that is merely "idle".
