The discovery of odor - detecting receptors in the fruit fly Drosophila may help scientists better understand how insects and eventually other animals process olfactory information and how odors... (hhmi.org)
These regions receive quite crude olfactory information very early in the brain's smell processing pathways, which may explain why people have such a hard time identifying odors. (sciencenews.org)
To shed new light on this question, the researchers focused on the development of the fly's smell circuit — the neurons that carry olfactory information from its antenna to the memory center of its brain — during the first few days after it is hatched. (sciencedaily.com)
