olfactory bulb

Spraying insulin up the nose — where brain tissue reaches outside the brain, making up the olfactory bulb — improves cognition in people with early Alzheimer’s dementia and with mild cognitive impairment.

They found that through olfactory training, people with smell loss and people with normal olfaction alike can achieve increases in the size or volume of the olfactory bulb and hippocampus.

A study published last year in the Journal of Neuroscience revealed that canines’ brain has a direct connection between their olfactory bulb, which processes smell, and their occipital lobe, which processes vision.

Rather than acquiring anosmia through a virus or traumatic injury, I was likely born without fully formed olfactory bulbs—a condition known as congenital anosmia.

In other words, it gets your olfactory bulb stoned.
