The olfactory bulb is an enlarged ending of the olfactory system, which is responsible for the sense of smell. It receives sensory input from the olfactory receptors located in the nasal cavity and processes this information before transmitting it to other areas of the brain, including the olfactory cortex. However, the olfactory cortex is not itself an enlarged ending of the olfactory system; it is a collection of brain regions responsible for analyzing and interpreting olfactory information.
