What activity do stimulants increase?

What activity do stimulants increase?

• A. Neural activity
• B. Behavioral activity
• C. Neural and behavioral activity
• D. Metabolic activity

Answer: (C)

Stimulants raise activity in the brain and in behavior. They boost signaling in neural circuits—especially dopamine and norepinephrine—by increasing release and blocking reuptake. This heightened neural activity translates into greater arousal, focus, and energy, which shows up as increased locomotion, wakefulness, and talkativeness. While metabolic rate can rise as a secondary effect, the core behavioral changes come from amplified neural signaling leading to heightened behavior. So, stimulants increase neural and behavioral activity.
