"rTMS using cTBS protocol with the following characteristics:~* Frequency: trains of 50 Hz (3 pulses) every 200ms (frequency of 5 Hz, in the range of theta band)~* Intensity: 80% of resting motor threshold (rMT)~* Location: consecutively on the left and right temporo-occipital cortex (MNI coordinates: left hemisphere: -50, -72, 4; right hemisphere:50, -66, 0)~* Duration: 40 seconds for each hemisphere, 80 seconds in total.~* Timing: Immediately before viewing pictures in pictorial memory task (off-line)"

DEVICE

rTMS (cTBS sham)

"rTMS using cTBS protocol with the following characteristics:~* Frequency: trains of 50 Hz (3 pulses) every 200ms (frequency of 5 Hz, in the range of theta band)~* Intensity: 0%~* Location: consecutively on the left and right temporo-occipital cortex (MNI coordinates: left hemisphere: -50, -72, 4; right hemisphere:50, -66, 0)~* Duration: 40 seconds for each hemisphere, 80 seconds in total.~* Timing: Immediately before viewing pictures in pictorial memory task (off-line)"

DEVICE
