I always supposed the neurons / receptors which transmitted touch and pain were the same, since they react to stimulus which are the same but with different intensity, and they just sent a stronger signal in the case of something that has to be interpreted as pain. Though recently I've read some articles that imply they aren't, even so they don't say it directly. Reading more information I found this,
A nociceptor ("pain receptor") is a sensory neuron that responds to damaging or potentially damaging stimuli by sending “possible threat” signals.
Types and functions
Mechanical nociceptors respond to excess pressure or mechanical deformation.
Are sensory receptors neurons?
Receptor cells are specialized neurons
Sensory receptors are primarily classified as chemoreceptors, thermoreceptors, mechanoreceptors, or photoreceptors.
Mechanoreceptors detect mechanical forces.
This doesnt give me a definitive answer, but it tells me both "sensory mechanoreceptors" and "mechanical nocireceptors" are neurons which responds to pressure/ mechanical forces. Are they supposed to be the same types of neurons named differently by different authors, or are they different types of neurons?
