Researchers at Karolinska Institutet in Sweden now show that another kind of neuron that normally allows us to feel pleasant touch sensation, can switch function and instead signal pain after nerve damage. The results, which are presented in the journal Science, can eventually lead to more effective pain treatments.

However, in a new study from Karolinska Institutet published in the journal Nature Neuroscience, scientists show that the system comprises different neurons that regulate specific physiological functions, such as erectile muscle control.
