Definition
The first, superficial computational layer of the vertebrate olfactory bulb consists of discrete spheroid clusters of neuropil known as glomeruli. Within these glomerular microcircuits, primary olfactory sensory neuron axonal arbors interact with the dendrites of olfactory bulb principal neurons and multiple classes of local interneurons. The computations within and among these glomerular microcircuits determine how the primary sensory information arriving in the olfactory bulb is transformed prior to subsequent computations in the deep olfactory bulb and other regions of the brain. Among the important computations in the glomerular layer are a high-dimensional form of contrast enhancement and a competitive normalization of global afferent activity levels via small-world network circuitry.
Detailed Description
The Olfactory Bulb
The olfactory bulb (OB) is the target of primary olfactory sensory neuron (OSN) axons that project across the blood–brain barrier at the cribriform...
