Which region is associated with voluntary initiation and sustained attention?

• A. Parietal lobe
• B. Prefrontal cortex
• C. Occipital lobe
• D. Cerebellum

Answer: (B)

Voluntary initiation and sustained attention rely on executive control processes housed in the prefrontal cortex. This region supports goal-directed behavior, planning, and maintaining task rules in working memory, which allows you to start a task without external prompts and to keep focusing over time despite distractions. It works with the frontal-parietal control network to implement top-down control, shaping attention to task-relevant information and suppressing irrelevant input. The parietal lobe contributes more to directing attention and spatial aspects, the occipital lobe handles visual processing, and the cerebellum coordinates timing and motor aspects. Because initiating actions and maintaining focus are core executive functions, the prefrontal cortex best fits this description.
