Brak interwencji: Healthy control group
No intervention is conducted in the healthy control group.

Eksperymentalny: Intervention group of amphetamine addiction
A 20-minute tACS intervention of real-stimulus is conducted twice a day for a total of 10 days in the intervention group of amphetamine addiction.
|
The adhesive electrodes were placed at F3 and F4 positions of the 64-bit EEG caps of the 10-20 system, corresponding to bilateral prefrontal lobes respectively.
Before the intervention, the individual alpha frequency (IAF) of the subjects was measured according to the average peak value of α waves at dorsolateral prefrontal cortex in the closed state.
Then an alternating current at θ frequency (θ = IAF - 5Hz) was applied to each subject based on its IAF value.
The amplitude of stimulation was increased with a step of 20μA starting from 0. When the subjects had a slight prickling sensation or optical illusion, the stimulation current was decreased with a step of 20μA until the sensation disappeared.
The current value at this time was used as the stimulation current of the subjects.

Pozorny komparator: Control group of amphetamine addiction
A 20-minute tACS intervention of sham-stimulus is conducted twice a day for a total of 10 days in the control group of amphetamine addiction.
|
The adhesive electrodes were placed at F3 and F4 positions of the 64-bit EEG caps of the 10-20 system, corresponding to bilateral prefrontal lobes respectively.
The actual stimulation waveform was just implemented in the first 60 s (or more longer) and then faded out.
