which part of the brain is involved in decision making
Prefrontal cortex Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex.[2] This brain region has been implicated in planning complex cognitive behavior, personality expression, decision making, and moderating social behavior.[3] The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals.[4]
