Active avoidance of potential threat is reflected in oscillatory brain activity.

ABSTRACT: Detecting and responding to real and potential threats is crucial for self-preservation. While most studies have focused on passive threat perception, the neural mechanisms underlying active defensive behaviors like avoidance remain poorly understood. A secondary analysis was conducted on previously published EEG data from 95 participants who performed a task with three cue conditions. Each trial featured a colored cue (red, yellow, or green) followed by a naturalistic image: red signaled an unavoidable electric shock, yellow an avoidable shock requiring a rapid response, and green no shock. Time-frequency analyses revealed differences in oscillatory activity within the alpha and mu rhythms across conditions. Parietal alpha activity following cue and image onset, and left central mu activi
