Treatment and study plan

tDCS

Device

Multi-channel tDCS will be applied over the executive network for 20 minutes at 4mA

Sham tDCS

Device

Sham tDCS will consist of applying the same parameters as for active but the corresponding device will be turned off after 30 seconds as to simulate the initial sensation of the active current. A current of 2mA will still be used (but turned off after 30 sec). The electrodes that will be used will be the same as for the active tDCS condition and the electrodes placement as well.

Music

Other

Subjects will listen to their preferred music for 20 minutes

White Noise

Other

Subjects will listen to a white noise for 20 minutes

Primary outcomes

  1. 3-back

    Time frame: It will be measured over the course of four weeks

    The subject is presented with a sequence of stimuli, and the task consists of indicating when the current stimulus matches the one from 3 steps earlier in the sequence.

Secondary outcomes

  1. Stroop

    Time frame: It will be measured over the course of four weeks

    The subject has to name the font color of a printed word, while it can have a mismatch between the word and the color (ex: green is written in red).

  2. EEG - alpha power

    Time frame: It will be measured over the course of four weeks

    Brain activity will be measured with an electroencephalography collected at rest. We will first look at the change in alpha power (8-12Hz)

  3. EEG - beta power

    Time frame: It will be measured over the course of four weeks

    Brain activity will be measured with an electroencephalography collected at rest. We will also look at the change in other frequency bands (e.g., beta, theta, delta).
