Neuronal Activation Patterns in the Olfactory Bulb (video) Stowers Institute for Medical Research Share Print E-Mail Loading video... Caption Any time an odor molecule interacts with an olfactory receptor in the nasal cavity, an electrical signal travels to so-called glomeruli in the olfactory bulb. Each glomerulus receives input from olfactory receptor neurons expressing only one type of olfactory receptor. The overall glomerular activation patterns within the olfactory bulb are thought to represent specific odors.
