大脑皮层-刺激同一性处理过程中的神经计算还没有得到很好的理解，特别是信息如何在不同的皮层区域之间转换。在这里，我们比较了上级颞回（STG）和腹外侧前额叶皮层（vPFC）的神经元编码的身份的听觉刺激的能力，这两个领域是腹侧处理流的一部分，为听觉刺激的身份。而在这两个领域的神经元的反应是可靠的调制不同的发声，STG响应代码显着更多的发声比vPFC。总之，这些数据表明，STG和vPFC差异编码听觉身份，这表明，大量的信息处理发生在这两个领域之间。这些研究结果是一致的假设，STG和vPFC是一个功能电路的一部分，身份分析。
The neural computations that underlie the processing of auditory-stimulus identity are not well understood, especially how information is transformed across different cortical areas. Here, we compared the capacity of neurons in the superior temporal gyrus (STG) and the ventrolateral prefrontal cortex (vPFC) to code the identity of an auditory stimulus; these two areas are part of a ventral processing stream for auditory-stimulus identity. Whereas the responses of neurons in both areas are reliably modulated by different vocalizations, STG responses code significantly more vocalizations than those in the vPFC. Together, these data indicate that the STG and vPFC differentially code auditory identity, which suggests that substantial information processing takes place between these two areas. These findings are consistent with the hypothesis that the STG and the vPFC are part of a functional circuit for auditory-identity analysis.
