Can't smell the fragrance of women?

Various smells linger in our living environment: floral, incense, mosquito-repellent incense; foot odor, body odor, and putrid smell

In fact, the memory and recognition of odors are inseparable from the constancy of perception, which requires the brain to maintain a stable representation of sensory input

Recently, "Nature" published an online publication of the title "Representatio" by Andrew JP Fink and other researchers from Columbia University in the United States.

The human sense of smell first starts from the contact of odor with cells in the olfactory zone, and is transmitted to the pear-shaped cortex through the olfactory bulb.

In order to verify this theory, the researchers used a variety of different odors to stimulate the mice every 8 days, monitored the response of the mouse anterior pear-shaped cortex to odor stimuli through probes, and estimated the response speed and accuracy.

So, can linking odor stimuli with behavioral factors increase the stability of the odor response in the pear-shaped cortex? The researchers applied a fear stimulus to the mice, but the results showed that the fear condition did not seem to stabilize the odor-induced response in the pear-shaped cortex

In fact, we may be easier to recognize the odors we often smell

How does this drift phenomenon occur? Researchers believe that this may be the result of continuous learning and coverage, or it may be related to the unstructured network structure of the pear-shaped cortex
