Researchers unlock new secret to how smells are detected
Date:3/25/2011

the thalamus in the brain, Restrepo said. So the exact path odors take to the brain and how they can trigger often vivid reactions is still not fully understood. The new research suggests that perhaps part of the answer lies within the dialogue between olfactory bulb and cortex.

In describing their work, the researchers noted that "olfaction is a primitive sensory system connected to the brain in a fundamentally different way from other systems."

"Decision-making in olfaction is challenging with a large number of input dimensions and hundreds of olfactory receptors," they wrote. "We show that information about what odors predict is integrated into the earliest stages of neural encoding compared to other senses."
