人们对理解人类语言系统的个体发生和个体发育有着相当大的兴趣，然而，在这两个领域的界面上的神经生物学工作却并不存在。语言中的句法过程建立在接收者的感觉处理和排序能力之上。虽然我们更好地了解了人类大脑中与语言相关的个体发育变化，但特定人类发育阶段的神经生物学过程如何与系统发育密切相关的物种的神经生物学过程进行比较仍然是一个谜。为了解决这一知识差距，我们测量了EEG事件相关电位（ERP）在两个猕猴使用开发的范式，以评估人类婴儿和成人的大脑电位与非相邻的顺序关系的音节三胞胎序列的处理。频繁的标准三联体序列穿插着不频繁的语音音高或非相邻的规则偏差。猴子的ERP显示出早期音高和规则偏差的不匹配反应，这与先前在人类婴儿中报道的反应惊人地相似。这与成年人后来对规则偏差的ERP反应相反。这些结果揭示了非相邻序列排序关系在灵长类动物大脑中是如何处理的，并为进化上保守的神经生理学效应提供了证据，其中一些效应与人类早期发育阶段的效应非常相似。
There is considerable interest in understanding the ontogeny and phylogeny of the human language system, yet, neurobiological work at the interface of both fields is absent. Syntactic processes in language build on sensory processing and sequencing capabilities on the side of the receiver. While we better understand language-related ontogenetic changes in the human brain, it remains a mystery how neurobiological processes at specific human development stages compare with those in phylogenetically closely related species. To address this knowledge gap, we measured EEG event-related potentials (ERPs) in two macaque monkeys using a paradigm developed to evaluate human infant and adult brain potentials associated with the processing of non-adjacent ordering relationships in sequences of syllable triplets. Frequent standard triplet sequences were interspersed with infrequent voice pitch or non-adjacent rule deviants. Monkey ERPs show early pitch and rule deviant mismatch responses that are strikingly similar to those previously reported in human infants. This stands in contrast to adults’ later ERP responses for rule deviants. The results reveal how non-adjacent sequence ordering relationships are processed in the primate brain and provide evidence for evolutionarily conserved neurophysiological effects, some of which are remarkably like those seen at an early human developmental stage.
