A new study suggests that the inner sense of our cardiovascular state, our "interoceptive awareness" of the heart pounding, relies on two independent pathways, contrary to what had been asserted by prominent researchers. The University of Iowa study was published online this week in the journal Nature Neuroscience by researchers in the department of neurology in the Roy J. and Lucille A. Carver College of Medicine and the graduate programs in neuroscience and psychology. The researchers found...

The brains of thrill seekers differ from those of who avoid risky behavior, U.S. researchers suggest. Psychologists Jane E. Joseph, Xun Liu, Yang Jiang and Thomas H.

Both groups were shown a variety of photographs -- ranging from mundane scenes of...

Planning entails making predictions. In an uncertain environment, however,...

Until now, though, economists have not had a way to incorporate such emotions into their models of investors' strategies. However, in the September 1, 2005, issue of Neuron, Camelia M.
