Final answer:
Repetitive habits are linked to the basal ganglia, which control movement and regulate motivation, and the cerebellum, which is involved in motor learning and implicit memory formation.
Step-by-step explanation:
The part of the brain that is related to repetitive habits is the basal ganglia. This area plays crucial roles in movement control, posture, and regulating motivation. The repetitive nature of activities performed by individuals such as computer operators or professional violinists can be understood in the context of the function of the basal ganglia.
The cerebellum is also involved in the creation of implicit memories like procedural memory, motor learning, and classical conditioning, which are important for habitual actions and skills.
In addition to these areas, studies on brain function in drug addicts suggest that dopamine action in the brain is also a significant factor in repetitive behaviors, particularly those associated with addiction. The complex interplay of these areas of the brain is necessary for the establishment and maintenance of habits and routines.
