What is the spinal cord phenomenon characterized by temporal summation, where a neuron's response grows larger with repetitive low-frequency input to C-fibers?

Answer

Wind-up

Wind-up is a spinal mechanism driven by repetitive, low-frequency stimulation of C-fibers. This causes the responding neuron to exhibit temporal summation, meaning its response amplitude increases with each successive stimulus, leading to hypersensitivity.
