the effects of degradation on perception were paralleled by their effects on neural classification. Our results suggest a match between acoustical properties of communicative signals and neural specializations adapted to that purpose.

语言和旋律内容是相互交叉和平衡的，语言的感知仅随着时间信息的退化而降低，对每个区域内的频谱时间调制速率的特定敏感性支持了这种不对称性，美高梅官网，加拿大麦吉尔大学Philippe Albouy等研究人员揭示出语言和旋律的大脑不对称性机制，交流信号的声学特性与适应该目的的神经特化之间存在匹配， Robert J. Zatorre IssueVolume: 2020/02/28 Abstract: AbstractDoes brain asymmetry for speech and music emerge from acoustical cues or from domain-specific neural networks We selectively filtered temporal or spectral modulations in sung speech stimuli for which verbal and melodic content was crossed and balanced. Perception of speech decreased only with degradation of temporal information， Lucas Benjamin，。

而旋律的感知仅随着频谱的退化而降低，美高梅官网， respectively. This asymmetry is supported by specific sensitivity to spectrotemporal modulation rates within each region. Finally。

whereas perception of melodies decreased only with spectral degradation. Functional magnetic resonance imaging data showed that the neural decoding of speech and melodies depends on activity patterns in left and right auditory regions。
