Olfactory bulb: Regions, Structure & Function

The olfactory bulb (Latin: bulbus olfactorius) is a neural structure in the forebrain of vertebrates that is involved in olfaction, or the sense of smell. It transmits olfactory information to the other brain regions including the amygdala, orbitofrontal cortex (OFC) and hippocampus where it contributes to emotion, memory and learning.
