These fibers carry pain signals. When they are more active than large fibers, they "open" the gate, allowing the brain to perceive pain. Large nerve fibers (Normal touch):

The pain gate theory posits that certain nerve fibers, known as nociceptors, are responsible for transmitting pain signals to the spinal cord and eventually to the brain. However, the theory also suggests that there are other nerve fibers, called mechanoreceptors, that can modulate or "close" the pain gate, effectively reducing the transmission of pain signals. This modulation occurs in the spinal cord, where the signals from both nociceptors and mechanoreceptors are processed. These fibers carry pain signals
