Some interesting things about our sense of smell: According to wikipedia, it is our accessory olfactory system (as opposed to the main olfactory system) that smells the fluid-phase chemicals.
In the first study to examine living nerve cells from patients with psychiatric disease, scientists from the Monell Chemical Senses Center, the University of Pennsylvania, and collaborating institutions report altered nerve cell function in olfactory receptor neurons from patients with bipolar disorder.
Similar to a visuospatial sketchpad where the brain briefly stores images, this function can be likened to an olfactory flacon (the French word for flask, often used to describe a vessel for perfume), where the brain briefly stores odors.
a gene encoding a transneuronal tracer in olfactory sensory neurons.
Probably carcinogenic, but the olfactory was the sense most closely linked to memory, so it was worth it for the nostalgia hit.
In the mammalian nose, smelling takes place in tissue called the olfactory epithelium.
It does seem to have, it's so rare, that it's hard to say that there's a characteristic pattern, where, you know, some people may actually sort of get it into their nose and subsequently sort of travels along a nerve called the olfactory nerve, all the way back into their brain.
For a long time, it has been known that the olfactory receptor cells are located far up in the nose, and that they send their thin neural processes through small canals in the bone directly to the part of the brain called the olfactory bulb.
These cells, called olfactory receptor neurons, are located just inside the nose, and are similar in many ways to cells within the brain, but are easier and safer to get to.
Probably car cinogenic, but the olfactory was the sense most closely linked to memory, so it was worth it for the nostalgia hit.
