The presence of neurons in macaque temporal cortex and amygdala which fire selectively in response to social stimuli has been demonstrated by several investigators. The extent to which such neuronal populations may respond to a broad range of social features, including expressive movements and interactions, has not been fully explored due to the difficulty of presenting such complex stimuli in a controlled fashion. We describe a method for presenting moving segments of macaque behavior, visual and auditory, to animal subjects during single unit recording. The method permits a broad range of stimuli to be used both as probes and as controls. In addition, a novel technique for monitoring eye position in alert macaque subjects is described. We present results from the medial amygdala and adjacent cortex, demonstrating that neurons in these regions respond selectively to features of the social environment.
几位研究人员已经证明，猕猴颞叶皮质和杏仁核中存在对社交刺激有选择性反应的神经元。由于难以以可控方式呈现此类复杂刺激，这些神经元群体对包括表情动作和互动在内的广泛社交特征的反应程度尚未得到充分探索。我们描述了一种在单神经元记录期间向动物受试者呈现猕猴行为的视觉和听觉动态片段的方法。该方法允许将广泛的刺激用作探针和对照。此外，还描述了一种监测清醒猕猴受试者眼睛位置的新技术。我们展示了来自内侧杏仁核和相邻皮质的结果，表明这些区域的神经元对社交环境特征有选择性反应。
