Influence of repetitive magnetic stimuli on verbal comprehension.

The influence of repetitive magnetic transcranial stimulation over the temporo-parietal cortex on verbal comprehension was investigated in 44 healthy subjects. In right-handed subjects, trains of 50 Hz magnetic stimuli over the left hemisphere produced more errors than stimulation over the right hemisphere. The result is not very clearcut, however; thus the test cannot be used for diagnostic investigation of language dominance.
