The paper describes efforts to trace neural projections from single glomeruli within the mouse olfactory bulb to their targets in the cortex; our data reveal that different regions of the olfactory cortex receive distinct patterns of projection (ranging from totally diffuse to stereotyped and segregated), suggesting that each region of the olfactory cortex may play a unique role in building odor percepts and facilitating odor-driven behaviors.
This paper represents the collaborative efforts of the Axel and Datta labs, and in particular the work of a spectacular graduate student of Richard's, Dara Sosulski. Congrats to all!
