Risky behaviour through genetic and neuroanatomic dispositions
2021
University of Pennsylvania, Philadelphia, USA
Brain scans of 25,000 people were used to investigate the basis and mechanisms of risky behaviours (drinking, smoking, driving and sexual behaviour) by determining the correlation of genetic and neuroanatomical traits. Certain genetic dispositions promote risky behaviour; moreover, functional and anatomical differences were found in the brains of risk-taking subjects. These could also be discovered in the cerebellum, which was previously thought to be predominantly responsible for fine motor skills but seems to play a role also in decision-making processes.
Genetic underpinnings of risky behaviour relate to altered neuroanatomy
