In three patients stimulation of the frontal speech area resulted in one or more of the following symptoms: speech arrest, writing arrest, or impaired rapid alternating movements of the tongue, fingers or toes. Speech arrest could be altered at individual points either with or without impairment of rapid movements or writing, but writing was not impaired without concomitant difficulties with either speech or rapid finger movements. Our data suggest that the frontal speech area may function to integrate complex motor functions, some speech related and others not. We also confirm previous conclusions that Exner's writing centre is not separate from Broca's area and that the writing defect in Broca's aphasia can occur without involvement of the motor strip.
在三名患者中，刺激额叶言语区导致出现以下一种或多种症状：言语停顿、书写停顿，或舌头、手指或脚趾快速交替运动受损。言语停顿可在个别点发生改变，无论快速运动或书写是否受损，但如果没有言语或手指快速运动方面的伴随困难，书写不会受损。我们的数据表明，额叶言语区可能起到整合复杂运动功能的作用，其中一些与言语相关，另一些则无关。我们还证实了先前的结论，即埃克斯纳书写中枢与布洛卡区并非分开，布洛卡失语症中的书写缺陷可在运动区未受累的情况下出现。
