Which portion of the cerebral cortex lies just behind the forehead; involved in speaking and muscle movements and in making plans and judgments?

Localization of function in the brain is being tested here. The area just behind the forehead is the frontal lobes, which encompass the motor cortex that controls voluntary muscle movements and areas involved in speech production, as well as the prefrontal regions responsible for planning, decision making, and judgment. This combination of coordinating movement, producing speech, and guiding higher-order thinking matches the frontal lobes’ roles. In contrast, the back part of the brain, the occipital lobes, handles vision; the temporal lobes are key for hearing and language comprehension; and the parietal lobes process sensory input and spatial relationships. These regions don’t align with the description of being located behind the forehead and involved in speaking, movement, planning, and judgment. Thus, the frontal lobes best fit the description.
