What describes the limitation of flow of pain information?

Modulation
Transduction
Transmission
Blocking

The correct answer is: Modulation

Modulation describes the limitation of the flow of pain information. Modulation refers to the process by which pain signals can be either amplified or dampened within the central nervous system. This process helps regulate and control the perception of pain. In contrast, transduction refers to the process by which noxious stimuli are converted into electrical signals by nociceptors, transmission involves the movement of pain signals from the site of stimulation to the spinal cord and brain, and blocking refers to the process of inhibiting the transmission of pain signals.
