Which of the following suggests that large-fiber activity in the spinal cord can prevent pain signals from reaching the brain?
A) McGurk's theory
B) place theory
C) gate-control theory
D) frequency theory
Large-Fiber Activity
The involvement or action of myelinated nerve fibers that are responsible for transmitting fast and sharp pain signals.
Gate-Control Theory
a theory proposing that the perception of pain is not a direct result of activation of pain receptor neurons, but rather its gate can be closed by signals from the brain.
- Elucidate on the bodily mechanisms that facilitate the perception of pain and the variables that modify its experience.

Final Answer :
C
Explanation :
The gate-control theory, proposed by Melzack and Wall, suggests that the presence of large-fiber activity in the spinal cord can inhibit the transmission of pain signals from smaller fibers to the brain, effectively "closing a gate" to pain.
