Antennal Lobe Stereopair

Different groups of insects show large differences of antennal lobe morphology while maintaining basic principles of cellular organization. Antennal lobe glomeruli are invaded by two major classes of neurons: multi-glomerular neurons, the processes of which invade several glomeruli, and uniglomerular neurons, the processes of which invade a single glomerulus.This example shows the dendrites of two "uniglomerular" neurons, each invading a single olfactory glomerulus in the antennal lobe of the cockroach Periplaneta americana. Cockroach glomeruli each usually contain only two such neurons. In contrast, the olfactory glomeruli of flies and moths contain dendritic trees belonging to as many as seven uniglomerular output neurons, an example of which is shown in the database "Mothbrain." The pair of images here comprise a stereopair taken with an "Edge microscope" (Edge Scientific Instrument Corporation, Santa Monica, CA 90404) specifically designed for this purpose. The 3-D effect can be obtained by viewing a hard copy of the image with a stereoviewer, or by fusion of the two images on the screen.
