Smells and food aromas often produce an intense emotional impact. What is the biological basis of this response?
What will be an ideal response?
The olfactory epithelium consists of nerve cells that synapse with the limbic system, which includes the hypothalamus, hippocampus, and amygdala, regions responsible for generating fear, rage, aggression, and pleasure and for regulating sex drives and reproductive cycles. Chemical stimuli thus feed into the most basic regions governing emotional response.
