The central processing pathways of the human olfactory system are not fully understood. The olfactory bulb projects directly to a number of cortical brain structures, but the distinct networks formed by projections from each of these structures to the rest of the brain have not been well-defined.

The oculomotor nerve is the third of 12 pairs of cranial nerves in the brain. This nerve is responsible for eyeball and eyelid movement. It follows the olfactory and optic nerves in terms of order.

This bundle of nerve fibers is made up of the axons of mitral relay neurons bound for the regions of the brain associated with the olfactory cortex. 7 Feb 2021 The medullary stria pathway is responsible for salivation in response to According to some authors, the Zero nerve or N nerve exists, which  The bulbus olfactorius and paleocortex are strongly correlated in.

The human olfactory pathways can be divided into three parts [ 1, 2] (Fig. 1 ): The olfactory receptors are located in the mucosa of the nasal cavities. From there olfactory nerves run to the olfactory bulb which is located inside the bony skull beneath the orbital forebrain.

It follows the olfactory and optic nerves in terms of order. BACKGROUND AND PURPOSE: Although the olfactory bulb volume as assessed with MR imaging is known to reflect olfactory function, it is not always measured during olfactory pathway assessments in clinical settings. We aimed to evaluate the utility of visual olfactory bulb atrophy and neuropathy analyses using MR imaging in patients with olfactory dysfunction.

These receptor cells are homologous to sensory neurons located in sensory ganglia. The olfactory nerve (CN I) is the first and most rostral of the cranial nerves. Along with the optic nerve, it is actually a peripheral outpost of the central nervous system.

These receptor cells are homologous to sensory neurons located in sensory ganglia. Two Parallel Olfactory Pathways for Processing General Odors in a Cockroach. In animals, sensory processing via parallel pathways, including the olfactory system, is a common design. However, the mechanisms that parallel pathways use to encode highly complex and dynamic odor signals remain unclear.

The olfactory nerve is sensory in nature and originates on the olfactory mucosa in the upper part of the nasal cavity. From the olfactory mucosa, the nerve (actually many small nerve fascicles) travels up through the cribriform plate of the ethmoid bone to reach the surface of the brain.
