One of 34 Fly Neurons that Helps Register Smell Preferences (IMAGE)
Caption
Image shows path traced by one of 34 cells, called mushroom body output neurons (MBONs), present in every fly brain (the brain is stained purple). A CSHL-led team finds that collectively, MBONs help individual flies register and act upon their preferences for various smells. The white arrow indicates the tiny cell body, or soma, of a single MBON; the dendrites that enable it to receive information from other neurons in the mushroom body are concentrated within the white box, in the mushroom body's central "stalk"; the brighter of the two green lines tracing back to the area around the soma is the axon, which conducts the MBON's signal to other cells. INSET: composite image showing location of the mushroom body (green) in the fly's head.
