Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study examines the effects of the combined use of two different non-invasive brain stimulation (NIBS) techniques targeting the DLPFC on stress reactivity and recovery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Transcranial Direct Current Stimulation (tDCS) will be combined with intermittent Theta Burst Stimulation (iTBS) in order to maximize the effects coming from each of the techniques on their own. A group of 74 healthy participants wil be submitted to two different stimulation protocols (sham tDCS + active iTBS and active tDCS + active iTBS) with one-week in between and results on stress reactivity will be examined. In order to improve therapeutic protocols, this study with healthy participants is a crucial first step in order to further conduct clinical studies with psychiatric samples.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

active tDCS + active iTBS

Participants will receive 20 minutes of active tDCS, during the last 7 minutes active iTBS will be applied.

Group Type ACTIVE_COMPARATOR

active tDCS

Intervention Type DEVICE

A current of 2 milliampère (mA) through electrodes of 5x5cm.

iTBS

Intervention Type DEVICE

54 cycles with 10 bursts of 3 pulses, train duration of 2 seconds and intertrain intervals of 6 seconds, results in 1620 pulses at 110% resting motor threshold.

sham tDCS + active iTBS

Participants will receive 20 minutes of sham tDCS, during the last 7 minutes active iTBS will be applied.

Group Type SHAM_COMPARATOR

sham tDCS

Intervention Type DEVICE

Similar set-up as in the active tDCS, but stimulation is too short to cause any effects.

iTBS

Intervention Type DEVICE

54 cycles with 10 bursts of 3 pulses, train duration of 2 seconds and intertrain intervals of 6 seconds, results in 1620 pulses at 110% resting motor threshold.
