简要总结
Transcranial electrical stimulation (tES) is a non-invasive form of brain stimulation that has previously been to shown to have therapeutic potential in traumatic brain injury (TBI) patients. In this study, the study team will use a brain activity monitor (electroencephalogram, EEG) and a computer-based task to observe the effects of different forms of tES, like transcranial direct current stimulation (tDCS) and transcranial pulsed current stimulation (tPCS), on impulse control and sustained attention in people with TBI. Additionally, the study team will measure how much tDCS and tPCS affect the brain activity of a specific area of the brain associated with impulse control and attention. Problems with response inhibition have been shown to make rehabilitation more difficult for people with TBI. It also reduces social functioning and can also negatively affect job performance, which ultimately lead to a decreased quality of life. A better understanding of the effects of tES in TBI patients could be informative in finding out what its therapeutic potential is for this population.

结局指标
主要结局
Average Reaction Time During Stop Signal Task
时间窗: Throughout study (1 hour)
The Stop Signal Task (SST) is an assessment which requires participants to respond to various stimuli with a specific action and to not respond when a "stop" stimulus is presented.
EEG power in all frequency bands
时间窗: Baseline and immediately post Stimulation
They will be fitted with a standard EEG cap consisting of 32 EEG electrodes placed in the 10/20 international system format, a standardized system for EEG electrode placement. Frequency bands will be measured.
