Some individuals lose their sense of smell, a condition called anosmia, as a result of traumatic brain injury. which cranial nerve is responsible for conveying information from the olfactory receptors to the brain? how would an individual with anosmia experience life differently from someone with a functional sense of smell?

Olfactory nerve is responsible for conveying information from olfactory receptor to brain.

Explanation:

Olfactory nerve is the shortest cranial nerve and directly connects olfactory receptor to brain. Olfactory nerve is responsible for sense of smell and to some extent sense of taste.

If any person loss their sense of smell due to some injury he will not  be able to smell anymore therefore he will not feel good among the people who have the sense of smell and will feel isolated.

Research shows that depression and anxiety level is high in  anosmic people. As olfactory nerve also control some sense of taste they also feel problem in eating different foods of different flavors.

probably since the potency of the cocaine, not a lot, but i've never done any research on cocaine so i wouldn't know, but i would also guess it would determine on the gap between sniffs or if you did it all at once, so i really don't know.
