Final answer:
The olfactory bulb has direct connections to the limbic system and the hypothalamus, which may explain emotional correlations with smells.
Step-by-step explanation:
The olfactory bulb has direct connections to the limbic system and the hypothalamus, which may explain emotional correlations with smells. In the brain, the olfactory neurons project from the olfactory epithelium to the olfactory bulb, which is composed of neural clusters called glomeruli.
From the olfactory bulb, olfactory signals travel directly to the limbic system and hypothalamus, where smells become associated with long-term memory and emotional responses.
