NEUROBIOLOGY OF HEMISPHERIC SPECIALIZATION IN PRIMATES

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 结构磁共振成像（MRI）和正电子发射断层扫描（PET）的研究进行检查神经解剖学和神经生理学相关的行为侧化。 使用基于体素的形态学，我们发现，猿类显示左半球不对称的前盖和后颞叶的灰质。 使用PET，我们发现声音和手势交流与几个重要的大脑区域的活动有关，包括额盖，尾状核和扣带回。 我们还发现，黑猩猩在处理特定物种的声音时，右半球表现出明显的激活。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Structural magnetic resonance imaging (MRI) and positron emission tomography (PET) studies were conducted examining neuroanatomical and neurophysiological correlates of behavioral lateralization. Using voxel-based morphology, we have found that apes show left hemisphere asymmetries in the frontal operculum and posterior temporal lobe for gray matter. Using PET, we have found that vocal and gestural communication is associated with activity in several important brain areas including the frontal operculum, caudate and cingulate gyrus. We have also found that chimpanzees show pronounced right hemisphere activation in the processing of species-specific sounds.
