In a new study scientists at NYU Langone Medical Center have shown that the sense of smell can be improved. The new findings, published online November 20, 2011, in Nature Neuroscience, suggest possible ways to reverse the loss of smell due to aging or disease. Smell is unique among our senses, explains Donald A. Wilson, PhD, professor of child and adolescent psychiatry at NYU Langone Medical Center and senior research scientist at the Emotional Brain Institute at Nathan S. Kline Institute for Psychiatric Research, who led the study. The olfactory bulb, a structure beneath the frontal cortex that receives nerve impulses from the nose, also has direct connections to the amygdala, which controls emotions and physiology, and to higher-order regions like the prefrontal cortex, involved in cognition and planning.
