Fig 3. Automatic AL map reconstruction and response patterns upon odor stimulation.

A: Unprocessed image of a representative AL stained with Fura-2, and with red border circumventing the area of recognized glomeruli. B-D: Heat maps of responses to sunflower, ylang-ylang and pheromone respectively (@ frame 50, 2 s after odor onset) in recognized regions of interest based on correlated activity in neighboring pixels. In each individually recorded antennal lobe the three glomeruli that made up the MGC were identified: cumulus (cum), dorsomedial anterior (dma) and dorsomedial posterior (dmp). The ordinary glomeruli comprised the rest of the AL.
