Olfaction plays a crucial role in human health and disease, with olfactory processing starting at the olfactory epithelium and proceeding through specific brain regions.
The piriform cortex is essential for odor processing, yet lacks a clear topographical representation of odor quality, raising questions about how olfactory information is organized.
Studies in animal models reveal that not only the piriform cortex but also the amygdala and entorhinal cortex are involved in central olfactory processing.
Human imaging studies align with animal research, showing activation in key brain areas like the amygdala and hippocampus during olfactory tasks.
