The Neurodevelopmental Basis of Homicidal Ideation

• In Event: Poster Session 2

Abstract

Through examinations of neurological abnormalities, genetic factors, and environmental influences on abnormal neurological functioning, this paper evaluates these neurological developmental influences to evaluate the respective correlations with criminal behavior, specifically homicide. This paper examines two key brain regions: the prefrontal cortex, crucial for decision-making, and the amygdala, responsible for emotional regulation. Key areas of environmental influence include substance abuse, which can disrupt brain chemistry and increase the likelihood of violent behavior, as well as upbringing, which plays a vital role in altering brain structure and neurotransmitter systems, potentially predisposing individuals to antisocial behavior.
This paper uses case studies, including Albert Fish and Charles Whitman, alongside empirical research to explore the complex relationship between brain development and criminal behavior. This meta-analysis utilizes neuroimaging, neuropsychological assessments, and longitudinal analyses, all of which provide evidence supporting that brain development significantly influences criminal tendencies, especially homicidal ideation.
