Unlike the aphasic syndromes, the organization of affective prosody in brain has remained controversial because affective-prosodic deficits may occur after left or right brain damage. However, different patterns of deficits are observed following left and right brain damage that suggest affective prosody is a dominant and lateralized function of the right hemisphere. Using the Aprosodia Battery, which was developed to differentiate left and right hemisphere patterns of affective-prosodic deficits, functional-anatomic evidence is presented in patients with focal ischemic strokes to support the concepts that (1) affective prosody is a dominant and lateralized function of the right hemisphere, (2) the intrahemispheric organization of affective prosody in the right hemisphere, with the partial exception of Repetition, is analogous to the organization of propositional language in the left hemisphere and (3) the aprosodic syndromes are cortically based as part of evolutionary adaptations underlying human language and communication.
与失语综合征不同，大脑中情感韵律的组织一直存在争议，因为情感韵律缺陷可能在左脑或右脑损伤后出现。然而，在左脑和右脑损伤后观察到不同的缺陷模式，这表明情感韵律是右半球的主导性和偏侧化功能。使用为区分情感韵律缺陷的左、右半球模式而开发的情感韵律测试组，对局部缺血性中风患者提供了功能解剖学证据，以支持以下观点：（1）情感韵律是右半球的主导性和偏侧化功能；（2）右半球情感韵律的半球内组织，除了重复部分外，类似于左半球命题语言的组织；（3）情感韵律缺失综合征是基于皮质的，是人类语言和交流潜在进化适应的一部分。
