Researchers discover a new migraine-associated mechanism

A mutation in the gene that codes the ionic channel TRESK, involved in the control of neuron irritability, causes the dysfunction of some neurons that increase neuronal activity and induce migraine pain.

Genetics

Scientists identify method to study resilience to pain

Scientists at the Yale School of Medicine and Veterans Affairs Connecticut Healthcare System have successfully demonstrated that it is possible to pinpoint genes that contribute to inter-individual differences in pain.
