Using a labeling technique that tracked the signal of single type of receptor, the group followed the signals of those receptors all the way to the brain...
...possible overlap of signals from different ORs is surprising because it implies that a single neuron in the brain could be stimulated by more than one type of receptor in the nose...
...experiments, a single receptor in the nose stimulated about 2 to 5 percent of the neurons in the olfactory cortex. The researchers had expected only about 0.1 percent of the neurons to be stimulated if the signals from receptors did not overlap...
Studying mice, Buck found the patterns for a given receptor were similar among the individual mice...
...TOXINS ATTACH TO CELL One of the toxins, called protective antigen, attaches to a receptor found on most cells. When seven of them find their mark, they latch together, forming a ring with a hole in its center. Then one of the other toxins--either a killing toxin or a swelling toxin--plugs the hole...
