Correction: The Use and Abuse of Transcranial Magnetic Stimulation to Modulate Corticospinal Excitability in Humans.

There is an error in the 10th sentence of the Abstract. The correct sentence is: Approximately 44% of respondents knew researchers who engaged in questionable research practices (range 30–81%), yet only 18% admitted to engaging in them (range 6–38%).

There is an error in the third and fourth sentences of the fifth paragraph in the Results. The correct sentences are: On average, 44% of respondents knew researchers who engaged in these practices (range 30–81%), whereas only 18% admitted to these practices (range 6–38%). About 80% of respondents knew researchers who screened their subjects to identify those that responded in a predictable way to various TMS protocols.

There are errors in Table 1. Please see the correct Table 1 here.
