Abstract
The objective of the study is to explore the characteristics of emotional stimulus in adolescents with violent behavior and
to identify the correlated dysfunctional regions of the brain. An event-related functional magnetic resonance imaging was
obtained while the participants passively viewed pictures with neutral or negative affective valence. 15 male adolescents
with violent behavior, ranging in age from 12 to 18 years old, and 16 healthy age-matched control subjects were enrolled in
the study. While looking at neutral pictures, several brain regions were activated more intensely in the violent group than
the control one. After digitally subtracting the control group, these areas included the bilateral amygdala, left orbital
gyrus, bilateral fusiform gyrus, and left visual cortex. While passively viewing negative pictures, the right inferior frontal
gyrus and the middle frontal gyrus were less activated in the violent group than the control group. Male adolescents with
violent behaviors have some dysfunctions during the processing and evaluation of information from external emotional stimulus.
These individuals are inclined to interpret neutral information as threatening stimulus.
