Descending pathways from the brain can influence the intensity and perception of pain.

### Why this is right The material identifies descending pathways from the brain as a way to modulate pain. Their influence can change pain intensity and perception. ### The concept Ascending pathways carry pain signals toward the brain. Descending pathways provide influence in the opposite direction, allowing brain activity to modify processing. Modulation means changing the strength or character of a response, not necessarily eliminating the input. ### Terms - **Descending pathway**: A route through which the brain influences lower neural processing. - **Modulation**: Adjustment of the intensity or character of a process. - **Ascending pathway**: A route carrying signals toward the brain. ### Remember Pain is modifiable: ascending signals carry input, while descending pathways can adjust its impact.
