Here when you see, hear, touch, or taste something, that sensory information first heads to the thalamus, which acts as your brain's relay station. The thalamus then sends that information to the relevant brain areas, including the hippocampus, which is responsible for memory, and the amygdala, which does the emotional processing.

But with smells, it's different. Scents bypass the thalamus and go straight to the brain's smell center, known as the olfactory bulb. The olfactory bulb is directly connected to the amygdala and hippocampus, this hippocampus can explain immediately trigger a detailed sence of that memory or even intense emotion.

This explains why we have at least 1,000 different types of smell receptors but only four types of light sensors and least four types of receptors for touch.

Some science says, the memories may be saved in a part of the olfactory bulb itself. The part responsible is a complex structure called the piriform cortex.

The piriform cortex connects to all sorts of places in the brain, including a higher-level structure called the orbitofrontal cortex. Now this structure is generally responsible for making judgments about sensory input, this sweater feels something interesting, so you touch it again; and you keen to take the last Chinese food when you jst trigger that smell; So out brain not only stores the information that we wanted but it stores the long term smells which love and lust .
