According to the gate control theory, when spinal gates open farther, what is the result?

According to the gate control theory of pain, the concept of "gates" refers to a neurological mechanism in the spinal cord that can modulate the perception of pain signals that are sent to the brain. When these gates open wider, they allow more pain signals to be transmitted to the brain, which results in a greater experience of pain.

In essence, the theory posits that both physical and psychological factors can influence whether the gates are open or closed. When the gates are open wider, it indicates that the pathways for pain signals are more accessible, leading to an intensified perception of pain. This explains why, for instance, heightened stress or anxiety may lead to an increased sensation of pain—because these emotional states can keep the gates open.

The other answer options would not align with the principles of gate control theory. For example, a decrease in pain experience would suggest that the gates are closed more effectively, blocking pain signals, which is the opposite of what occurs when the gates open wider.
