Read the given passage and answer the questions that follow.
Environmental or genetic influences antisocial conduct of a human being , which has an impact on behaviour, such as conduct disorder. In a recent study conducted, young people with conduct disorders had their brains examined, along with controls that were healthy and did not have the disease. The thickness of various regions of the cortex and the brain’s outer layer was measured using the scanned images. It was demonstrated in the study that conduct disorder is a psychiatric condition rather than adolescent disobedience. Awareness, perception, attention, memory and language are all impacted by the cortex. The findings of the study were unexpected. They demonstrated distinct disparities between adolescents whose behavioural issues began in adolescence and those whose issues began earlier in life. Although both groups were different from healthy controls, it was discovered that distinct regions of the cortex in the teenagers who had experienced early-onset behavioural issues were thicker in comparison to the healthy participants.
Which of the following was measured in scanned images?
