Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
recruitment period : 2012.12.05-2013.03.07 type of location: medical clinic through public announcement

Pre-Assignment Details

15 participants recuired: 15 screened, 0 excluded, 3 participants dropped oupt (3 participants withdrawed because of their long-distant commute before group assisgnment)

Reporting Groups
  Description
rTMS Over MTG, STG, Sham

3 sessions of Repetitive magnetic stimulation (rTMS) were applied to participants 3 sessions of rTMS were determined by a random sequence (eg. MTG-STG-Sham, Sham-MTG-STG, STG-MTG-Sham etc..0) The sequence of stimulation was counter-balanced across subjects.

different sessions was performed after washout period (at least 3 days). The coil was placed perpendicularly to the scalp during sham rTMS sessions.

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Same patients were stimulated over 2 different regions and with sham stimulation in a random order

Reporting Groups
  Description
rTMS Over MTG, STG, Sham

3 sessions of Repetitive magnetic stimulation (rTMS) were applied to participants.

3 sessions of rTMS were determined by a random sequence (eg. MTG-STG-Sham, Sham-MTG-STG, STG-MTG-Sham etc.) MTG: middle temporal gyrus STG: superior temporal gyrus

The sequence of stimulation was counter-balanced across subjects. different sessions was performed after washout period (at least 3 days). The coil was placed perpendicularly to the scalp during sham rTMS sessions.

  Outcome Measures

1.  Primary:   The Change of Reaction Time Between Before and After Stimulation in Each Session (MTG, STG, Sham)   [ Time Frame: change between before and after the TMS stimulation for each sessions (at session 1, session 2, session 3) ]
