To my knowledge as other stimuli pain is coded by rate code of single
neurons  and population code by the number of involved neurons but
unlike pressure does not adapt....... etc
What don't exacly understand is what you mean by frequency. Frequency
where ? In peripheral Axons, In thalamus, In Sensory cortex ? Could
you specify?
