Neuroscience: Brain Mechanisms of Blushing

The dorsal hypothalamic area regulates increases in body temperature in response to stress, but precise mechanisms are unclear. A new study suggests that glutamatergic neurons in this brain area regulate this action and, surprisingly, may also be involved in blushing.
