you have so many nurons all around ur bodey that is about as fast as lightnig, that travels to a small part of ur brain
Yes there are people with no sense of smell, i think it can happen because of head/brain trauma
As a filter and a sensor for the brain, when you smell something it sends signals to the brain telling you what it is you are smelling.
No one knows what it smells like.
Thalamus
why can the odor of perfume reach you?
it says "oh something smells i wonder what it is" and goes and looks for it in the file cabinets. if it finds the same smell then he uses that if he doesn't then he puts in in a new file
well smell and taste all have to do with the sensory organ pick up data transmitting it as a electrochemical signal and your brain decoding it. If you cant smell you can not taste the food you are eating.

smell signals from the nose is taken to the brain. The flavor is then perceived by the brain and taste signal is sent to taste buds that are present on the tongue If we dont breathe, and try eating it is not possible for us to get the taste and no signal would be send to the brain.
The receptors that actually bind with the molecules that we smell are called Olfactory receptor neurons. They pass their signal through the caribform plate, then down the olfactory nerve, and finally to the olfactory bulb in the brain.
A pheromone is a signal detected as a smell.
You can't smell without it.
you can smell a bad smell in your nose is because, when you inhale, your nose takes your ,"smellings" into the nose to something that takes the materials and sends a signal to your brain, which makes a bad scent
if you smell to many it can lead to brain damage
Whether it's something burning or any other smell that's not there, it's all in your head, and I mean that literally, I'm not joking.. Only way you can smell is through the olfactory nerve in your nose, which sends that signal to your brain.... Put briefly, you are having simple partial seizures in your temporal lobe..Abnormal electrical discharges in that part of the brain is creating this sensation of smell, but the smell does not exist...Go see a Nuerologist, and get an EEG and you will understand...It can be controlled with Meds..
to transfer nerve impulses to the brain
