DURHAM, N.C., July 29 -- Neurobiologists at Duke University Medical Center have captured the first detailed images of a living brain in the act of recognizing specific odor molecules. As reported in Neuron, the researchers refined an imaging technique used to visualize brain activity by increasing its resolution tenfold to detect changes in the tiny hair-thin olfactory structures, called glomeruli, in rats' brains. The objective was to visually detect a particular odorant triggering the activity of a specific glomerulus, one of the tiny basket-like structures covering the surface of the...Read full article
