Abstract Objective Studies have demonstrated that damage to Broca's area causes problems in phonological processing, but leaves semantic processing mostly preserved. The current investigation explored whether problems in phonological processing caused by injury to Broca's area extends to numbers. Method Patient LXM presented with an injury to the left anterior fronto-temporal cortex (including Broca's area). LXM completed a series of neuropsychological tests for general cognitive processing, mathematical processing, and language processing. Results LXM exhibited normal semantic processing but had difficulty in speech production for both words and numbers (e.g., reading characters and numbers, naming pictures, and reporting arithmetic facts). Conclusions Broca's area is likely within the neuronal circuit governing semantic-based articulation of words and numbers.

基于语义的数字和单词发音的通用神经回路：以 Broca 失语症患者为例

摘要 目的研究表明，布洛卡区的损伤会导致语音处理出现问题，但语义处理基本得以保留。目前的调查探讨了布洛卡区损伤引起的语音处理问题是否扩展到数字。方法 患者 LXM 出现左前额颞叶皮层（包括 Broca 区）损伤。LXM 完成了一系列针对一般认知处理、数学处理和语言处理的神经心理学测试。结果 LXM 表现出正常的语义处理，但在单词和数字的语音生成方面有困难（例如，阅读字符和数字、命名图片和报告算术事实）。结论 Broca'
