A newly identified pathway involving the spinal cord and two parts of the brainstem plays a key role in behavioral responses to an uncomfortable heat stimulus, according to a study in mice from the National Center for Complementary and Integrative Health’s Division of Intramural Research. The study was published in a recent issue of the journal Neuron.
