Key result
Threat-induced acute stress rapidly decreases dorsolateral prefrontal theta and alpha power during a shooting task.
Why the study?
Monitoring modulation of cortical activity by EEG measurements is a promising tool for assessing acute stress in real-world conditions, but its effectiveness needed testing.
Does mobile EEG with independent component analysis and source localization identify increased levels of acute stress in subjects performing a shooting task?
Population
Subjects performing a stationary shooting task using an airsoft rifle
Comparison
Stressful condition with threat of being fired at vs control condition without threat
Design
EEG study with independent component analysis and source localization

Mobile EEG may detect acute stress via prefrontal changes; hypothesis-generating for cardiovascular stress applications.
Does mobile EEG with independent component analysis and source localization identify increased levels of acute stress in subjects performing a shooting task?
p-value: p=<0.05
Mobile EEG combined with independent component analysis and source localization can effectively monitor and identify cortical changes associated with acute stress in real-world environments.
Schlink et al. (2017) studied Acute Stress (n=11). Threat of being shot at with an airsoft rifle vs. Control condition (shooting without threat) was evaluated on Spectral power in the theta and alpha bands in the dorsolateral prefrontal cortex (p=<0.05). The threat of being shot at during a shooting task successfully induced acute stress and resulted in a significant decrease in spectral power in the theta and alpha bands in the dorsolateral prefrontal cortex less than a second after pulling the trigger.
