Molecular basis of somatosensory specificity: The "Blurry Picture". Schematic representation of various subpopulations of modality specific primary sensory neurons, and of some of the putative transduction molecules that could be involved in their detection capacities for different stimuli. Data for the different channels potentially involved in nociception have been lumped together into an oversimplified model of polymodal neuron. Also, the stimuli refer to the preferred stimulus for each class of neuron but does not exclude the activation by other types.
