地位等级构成了人类社会的一项基本组织原则。然而，人们对处理表明状态的非语言线索的神经系统知之甚少。初步的神经心理学研究表明，腹外侧额叶和腹内侧前额叶皮质(VLPFC/VMPFC)和颞叶上皮质(STC)可能起作用。我们使用功能磁共振成像来描述这些角色的性质。分析显示，右侧VLPFC的信号变化与两个主要功能有关，归因于状态提示。状态提示行为温和，右侧VLPFC在高状态提示下比中性提示和低状态提示下信号增强。VLPFC还显示出高地位线索的信号增加，这可能与地位线索在调节配偶选择行为中所起的作用有关。连通性结果表明，VLPFC与VMPFC和STC之间存在显著的正连通性。我们建议VLPFC在处理层级线索时从这些区域提取信息，以促进社会适应行为。
Status hierarchies constitute a fundamental organizing principle of human society. However, little is known about the neural systems that process nonverbal cues that indicate status. Preliminary neuropsychological work has suggested a role for the ventrolateral and ventromedial prefrontal cortex (VLPFC/VMPFC) and the superior temporal cortex (STC). We used functional magnetic resonance imaging to delineate the nature of these roles. Analyses revealed signal changes in the right VLPFC in connection with two primary functions attributed to status cues. Status cues moderate behavior and the right VLPFC showed increased signal for high-status relative to neutral and low-status cues. The VLPFC also showed increased signal for high-status cues displayed by individuals of the opposite gender to the perceiver; this may be relevant to the role status cues play in moderating mate choice behavior. Connectivity results indicated significant positive connectivity between the VLPFC and both the VMPFC and the STC. We suggest that the VLPFC retrieves information from these regions when processing hierarchy cues to facilitate socially adaptive behavior.
