Mouse olfactory sensory neuron axons (green) innervate a glomerulus within the olfactory bulb. Dendrites of local interneurons (red) also innervate the glomerulus.

A mouse accessory olfactory bulb. Vomeronasal sensory neuron axons (red) and dendrites of projection neurons (green) converge on glomeruli that are less well-defined than those in the main olfactory bulb. Cell bodies are in blue.
