Mental stress causes carotid artery dilation and increases brain blood flow. A series of ultrasound experiments also found that this dilatory reflex was absent in people with high blood pressure.

Although the tiny roundworm Caenorhabditis elegans has only 302 neurons in its entire nervous system, studies of this simple animal have significantly advanced our understanding of human brain function because it shares many genes and neurochemical signaling molecules with humans. Now MIT researchers have found novel C. elegans neurochemical receptors, the discovery of which could lead to new therapeutic targets for psychiatric disorders if similar receptors are found in humans.
