A fairly comprehensive survey is offered of the effects which cortical and sub-cortical electrical stimulation have on language and speech. A survey is also given of the verbal consequences of resections or coagulations which generally follow electrical stimulation.
According to reports in the literature and our own observations, which are reported in this paper, acquired stuttering may occur in conjunction with focal or diffuse damage to the central nervous system. When the lesion is focal, it may be in the right or in the left hemisphere. When the left hemisphere is injured, acquired stuttering may be concomitant with aphasia. Indeed, in some cases the stutter-like repetitions appear to be an integral part of the aphasic syndrome. In other cases, on the contrary, the two disorders seem to be relatively independent of one another. Occasionally, stuttering is the only observable disorder in the linguistic-cognitive sphere.
