A Criminal Brain?
Does the brain of a murderer differ from the ‘normal’ brain? Is there a gene for criminality? How does the environment interact with biology to shape criminal behaviour? In an attempt to answer such questions, we will briefly consider historical accounts of how criminal brains differ from non-criminal brains, before turning our attention to 21st century theories of frontal lobe dysfunction, genetic and epigenetic explanations, and the complex association between mental illness and criminal behaviour.
