Abstract
EEG (Electroencephalography) has been widely used in neuroscience and psychology to study brain activity, including its relationship to behaviours such as aggression. Aggression is a complex behaviour that involves various neural circuits and can be triggered by multiple factors, such as psychological, environmental, and biological influences. The prefrontal cortex, especially the orbitofrontal and dorsolateral prefrontal regions, plays a key role in regulating impulsive and aggressive behaviour. Reduced activity in these areas is often linked to poor impulse control and increased aggression. EEG studies have shown that individuals exhibiting aggressive or antisocial behaviour often display abnormalities in the frontal lobe, such as decreased frontal theta or beta activity. Various research designs showed that decreased alpha waves and increased theta waves are often show significant relation with aggression. Resting-state EEG studies focus on spontaneous brain activity when an individual is at rest. Increased low-frequency (delta or theta) activity and decreased high-frequency (beta) activity in the frontal lobe can indicate dysregulation in the neural circuits responsible for emotion regulation and impulse control, which are closely tied to aggressive behaviours. However EEG is valuable for identifying the neural correlates of aggression and helping to develop targeted interventions aimed at reducing aggressive behaviour through neuromodulation techniques like neurofeedback or transcranial stimulation.
