The name granule cell has been used for a number of different types of neurons whose only common feature is that they all have very small cell bodies. Granule cells are found within the granular layer
Drawing of Purkinje cells (A) and granule cells (B) from pigeon cerebellum by Santiago Ramón y Cajal, 1899. Instituto Santiago Ramón y Cajal, Madrid, Spain.
The olfactory bulb 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 t
Granule cell
…are found within the granular layer of the cerebellum, the dentate gyrus of the hippocampus, the superficial layer of the dorsal cochlear nucleus, the olfactory bulb, and the cerebral cortex. Cerebellar granule cells account for the majority of neurons in the human brain. These granule cells receive excitatory input…
Human brain seen from below. Vesalius' Fabrica, 1543. Olfactory bulbs and olfactory tracts are the two protruding structures labeled "F".
Coronal image of mouse main olfactory bulb cell nuclei. Blue – Glomerular layer; Red – External Plexiform and Mitral cell layer; Green – Internal Plexiform and Granule cell layer. Top of image is dorsal aspect, right of image is lateral aspect. Scale, ventral to dorsal, is approximately 2mm.
Fossil endocast of a Tyrannosaurus cranial vault, showing extensive olfactory bulb (structure to the left). Tyrannosaur dinosaurs, as well as carnivorous animals in general, have highly developed olfactory bulbs to seek out prey.
