abstract = {Repetitive TMS (rTMS) with a frequency of 5–10 Hz is
widely used for language mapping. However, it may be
accompanied by discomfort and is limited in the number and
reliability of evoked language errors. We, here,
systematically tested the influence of different stimulation
frequencies (i.e., 10, 30, and 50 Hz) on tolerability,
number, reliability, and cortical distribution of language
errors aiming at improved language mapping. 15 right-handed,
healthy subjects (m = 8, median age: 29 yrs) were
investigated in two sessions, separated by 2–5 days. In
each session, 10, 30, and 50 Hz rTMS were applied over the
left hemisphere in a randomized order during a picture
naming task. Overall, 30 Hz rTMS evoked significantly more
errors $(20 ± 12\%)$ compared to 50 Hz
$(12 ± 8\%;$ p <.01), whereas error rates were
comparable between 30/50 and 10 Hz $(18 ± 11\%).$
Across all conditions, a significantly higher error rate was
found in Session 1 $(19 ± 13\%)$ compared to Session 2
$(13 ± 7\%,$ p <.05). The error rate was poorly
reliable between sessions for 10 (intraclass correlation
coefficient, ICC = .315) and 30 Hz (ICC = .427), whereas
50 Hz showed a moderate reliability (ICC = .597). Spatial
reliability of language errors was low to moderate with a
tendency toward increased reliability for higher
frequencies, for example, within frontal regions. Compared
to 10 Hz, both, 30 and 50 Hz were rated as less painful.
Taken together, our data favor the use of rTMS-protocols
employing higher frequencies for evoking language errors
reliably and with reduced discomfort, depending on the
region of interest.},
