The Complex Axon Guidance Problem in Olfactory Epithelium
In the in the mouse nose, there's like 20 million olfactory sensory neurons. Each neuron expresses one receptor, right, of 1000. And so what that means is that on average, a mouse nose will contain 10 to 50,000 neurons expressing a particular receptor. So we're now used to thinking about the olfactory bulb containing kind of a spatiotemporal map of the odor world as you kind of are smelling things. But information also goes directly from the olfitory bulb to the hippocampal formation to the entorhinal cortex. I'm just thought that the intimate connection between your nose to the bulb to theEntorhinal Cortex is part of why smells
