Intervention / Traitement |
|---|---|
|
Expérimental: ARM 1 - CONTROL
Subject given tDCS every day of the week (5 sessions) at 2 mA.
|
tDCS applied to to motor cortex every weekday (5 sessions), at 2mA ,during 20 minutes.Conductive rubber electrodes (7 x 5 cm = 35 cm2) covered by sponges soaked in saline will be used, held in place by a band.
The current will be gradually increased to the level of 2 mA over 30 seconds (to avoid the sensation of a flash).
Autres noms:
tDCS applied to the motor cortex every day of the week during 20 minutes, at 1mA first session, 1.5 mA second and third sessions, and 2mA fourth and fifth sessions, during 20 minutes.
Conductive rubber electrodes (7 x 5 cm = 35 cm2) covered by sponges soaked in saline will be used, held in place by a band.
The current will be gradually increased over 30 seconds (to avoid the sensation of a flash).

Expérimental: Arm 2 - INCREASING
Subjects given increasing intensity during tDCS across the week (Monday 1mA, Tuesday 1.5mA, Wednesday 1.5 mA, Thursday 2 mA, Friday 2mA).

Expérimental: ARM 3 - CYCLOSERINE
D-cycloserine (100 mg) given on the Monday and Thursday sessions, administering tDCS at 2 mA.
|
Transcranial Direct Stimulation applied to the motor cortex every day of the week (5 sessions) at 2mA, during 20 minutes. Conductive rubber electrodes (7 x 5 cm = 35 cm2) covered by sponges soaked in saline will be used, held in place by a band. The current will be gradually increased to the level of 2 mA over 30 seconds (to avoid the sensation of a flash). D-cycloserine, administered orally (capsules), 100 mg, twice a week (Monday and Thursday), prior to the tDCS session.
