olfactory bulb, structure located in the forebrain of vertebrates that receives neural input about odours detected by cells in the nasal cavity. The axons of olfactory receptor (smell receptor) cells extend directly into the highly organized olfactory bulb, where information about odours is processed. Within the olfactory bulb are discrete spheres of nerve tissue called glomeruli. They are formed from the branching ends of axons of receptor cells and from the outer (dendritic) branches of interneurons, known in vertebrates as mitral cells, that pass information to other parts of the brain. Tufted cells, which are similar to but smaller than ...(100 of 322 words)
