Final answer:
Response inhibition can be observed through brain scans like fMRI, which show increased brain activity in areas related to visual processing, integration, and motor function.
Step-by-step explanation:
The brain activity linked with response inhibition can be observed through brain scans, such as functional magnetic resonance imaging (fMRI). With fMRI, areas of the brain that are active during response inhibition tasks can be identified based on increased blood flow and activation. These areas include the visual sensory areas, integrating areas, and motor areas responsible for eye movement and button pressing with a finger.
