Thermoregulatory Responses To Lying Based on Age and Temperature

Abstract

The main goal that was trying to be achieved throughout the course of this project was to determine if a subject is lying, based on the body temperature of an individual. This can also be known as the thermoregulatory responses in the metopic suture and the apex region between male and females. When law enforcement tries to determine whether a subject is lying, they could be able to figure it out based on the subject’s facial temperature increasing or decreasing. The two points, forehead and nose, were chosen because there is a location in the brain called the insula, which is located deep within the lateral sulcus of the brain, which shows a difference in temperature when a lie is told.  Insula activates brown adipose tissue to release heat, causing this phenomenon to occur. Ten subjects were used. Thirty questions were posed to each subject, and they were permitted to tell either the truth or a lie. After every question, the forehead and nose temperatures were taken. The results showed that when male and females lie, their temperature increases. The explanation for this is the area in the brain called the insula, which is more active in females and people over the ages of eighteen. For high insular activity to happen, it means the brain is trying hard to perform a complex task.
