In Luria's model, the frontal and prefrontal areas are involved in planning.

• A. Regulate arousal.
• B. Reception and analysis of sensory information.
• C. Planning.
• D. Emotion regulation.

Answer: (C)

The frontal and prefrontal regions act as the executive control of behavior, coordinating goal-directed actions through planning. In Luria’s framework, the brain is organized into functional units, with the frontal (prefrontal) unit handling the deliberate organization and regulation of actions—planning, sequencing steps, and choosing strategies to achieve a goal. This is why planning is the best fit for what these areas do. Arousal regulation, by contrast, is mainly a subcortical process involving the brainstem and related systems. Reception and analysis of sensory information come from posterior sensory areas and their associations, not the frontal prefrontal system. Emotion regulation involves limbic circuits and their interactions with the frontal cortex, but the specific role attributed to the frontal/prefrontal unit in Luria’s model is the planning and orchestration of behavior.
