Definition Small intrinsic neuron in the glomerular l Small intrinsic neuron in the glomerular layer of the accessory olfactory bulb, with cell bodies surrounding the olfactory glomerulus. Equivalent to the periglomerular cell of the main olfactory bulb, but the glomeruli are less clearly differentiated. The cell body is 6-8 um in diameter, from which arises a short bushy dendrite that arborizes within a glomerulus, where it receives synaptic input from olfactory receptor cell axon terminals, and engages in dendrodendritic interactions with mitral/tufted cell dendrites. The axon distributes laterally within the extraglomerular region. Shepherd, Chen, Greer. Olfactory bulb.
