Quantity processing studies typically assume functional homology between regions within macaque and human intraparietal sulcus (IPS), where apparently similar locations respond to broadly similar tasks. However, macaque single cell neurophysiology is difficult to compare to human functional magnetic resonance imaging (fMRI); particularly in multivoxel pattern analysis and adaptation paradigms, or where different tasks are used. fMRI approaches incorporating neural tuning models allow closer comparison, revealing human numerosity-selective responses only outside the IPS. Extensive functional similarities support this novel homology of physical quantity processing. Human IPS instead houses a network responding to comparisons of physical quantities, symbolic numbers, and other stimulus features. This network likely reflects interactions between physical quantity processing, spatial processing, and (in humans) linguistic processing.
数量处理研究通常假设猕猴和人类顶内沟（IPS）内的区域具有功能同源性，在这些区域中，明显相似的位置对大致相似的任务做出反应。然而，猕猴的单细胞神经生理学很难与人类的功能磁共振成像（fMRI）相比较；特别是在多体素模式分析和适应范式中，或者使用不同的任务时。结合神经调谐模型的 fMRI 方法可以进行更密切的比较，结果表明，人类对数量的选择性反应仅出现在 IPS 之外。广泛的功能相似性支持了这种物理数量处理的新同型性。人类的 IPS 则包含一个网络，对物理数量、符号数字和其他刺激特征的比较做出反应。这个网络可能反映了物理数量处理、空间处理以及（在人类中）语言处理之间的相互作用。
