Brief Summary
The goal of the current clinical trial is to investigate whether transcranial magnetic stimulation (TMS) over specific brain areas can influence the perception of emotional images and emotional memory. TMS is a non-invasive superficial brain stimulation generated by a magnetic field. The results of the study aim to provide valuable insights for the use of TMS in the investigation of mental processes.

Outcome Measures
Primary Outcomes (1)
Emotional valence for aversive pictures
The mean valence rating of aversive pictures as assessed by a visual analogue scale assessed directly after TMS.
Immediately after the intervention, lasting for approximately 7 minutes
Secondary Outcomes (2)
Emotional arousal
Immediately after the intervention, lasting for approximately 7 minutes
Aversive episodic memory
Approximately one hour after the intervention
Other Outcomes (3)
Emotional valence for non-aversive pictures
Immediately after the intervention, lasting for approximately 7 minutes
Emotional arousal for non-aversive pictures
Immediately after the intervention, lasting for approximately 7 minutes
Non-aversive episodic memory
Approximately one hour after the intervention
Study Arms (2)
Participants starting with experimental condition
EXPERIMENTALBilateral continuous theta burst stimulation (cTBS) 30 Hz to the temporo-occipital cortex
Participants starting with control condition
ACTIVE COMPARATORActive control condition using bilateral continuous theta burst stimulation (cTBS) 30 Hz to the superior parietal cortex
Interventions
Bilateral continuous theta burst stimulation (cTBS) 30 Hz to the temporo-occipital cortex * Frequency: trains of 30 Hz (3 pulses) every 167 ms (frequency of 6 Hz, in the range of theta band) * Intensity: 100% of resting motor threshold (rMT) * Location: consecutively on left and right temporo-occipital cortex (MNI: -47, -77, 4; 50, -69, -4) * Duration: 33.3 seconds for each side * Timing: Immediately before showing IAPS pictures (off-line)
Active control condition using bilateral continuous theta burst stimulation (cTBS) 30 Hz to the superior parietal cortex * Frequency: trains of 30 Hz (3 pulses) every 167 ms (frequency of 6 Hz, in the range of theta band) * Intensity: 100% of resting motor threshold (rMT) * Location: consecutively on left and right superior parietal cortex (MNI: -17, -70, 60; 17, -70, 60) * Duration: 33.3 seconds * Timing: Immediately before showing IAPS pictures (off-line)
