Gray matter in the brain is made up of most of the major cellular organs of the nerve cells of the central nervous system that perform basic brain functions such as muscle control, sensory perception, decision-making, and self-control.
The researchers used brain scans and genetic data studies of 12,675 participants in the UK Biobank database.

They focused on four high-risk behaviors, including smoking, drinking, rambling and speeding, and measuring the total amount of gray matter in the brains of study participants.
In the end, the study reached three conclusions. One is that there are no special regions involved in risky behavior in the brain. However, in the brains of risk takers, many areas have been anatomically altered.
The other is that a lower volume of gray matter is associated with a greater tendency to take risks in three brain regions: the amygdala, hippocampus and cerebellum.
Third, genetic factors only explain 3% of the highest risk behaviors when studying almost 300,000 people who use genetic modification methods.
The results of the previous study were confirmed after considering other resonant factors, including total brain size, age, gender, sensitivity, alcoholic status, and genetic factors.
The study authors concluded that family, environmental, and genetic factors, as well as their correlations, can promote risky behaviors.
