The accessory olfactory bulb resides on the dorsal-posterior region of the main olfactory bulb and forms a parallel pathway. Destruction of the olfactory bulb results in ipsilateral anosmia, while irritative lesions of the uncus can result in olfactory and gustatory hallucinations. Flow of olfactory information from receptors to glomeruli layer
Allomones include flower scents, natural herbicides, and natural toxic plant chemicals. The info for these processes comes from the vomeronasal organ indirectly via the olfactory bulb. [16] The main olfactory bulb's pulses in the amygdala are used to pair odors to names and recognize odor to odor differences. [17] [18]
The sensory receptors of the accessory olfactory system are located in the vomeronasal organ. As in the main olfactory system, the axons of these sensory neurons project from the vomeronasal organ to the accessory olfactory bulb, which in the mouse is located on the dorsal-posterior portion of the main olfactory bulb.
Inside of these olfactory organs there are neurons called olfactory receptor neurons which, as the name implies, house receptors for scent molecules in their cell membrane. The majority of olfactory receptor neurons typically reside in the antenna. These neurons can be very abundant; for example, Drosophila flies have 2,600 olfactory sensory ...
Olfactory senses are generally more heightened for a terrestrial species than for an aquatic, as airborne volatiles are more important to detect than water-soluble scents in land animals. Support for this theory is exemplified through the fish-to-tetrapod transition, where animals began to populate terrestrial niches and a tremendous expansion ...
Connecting the olfactory bulb and the nasal cavity is the olfactory nerve. Some researchers worry the olfactory pathway may also be an entry point for microplastics getting into the brain, beyond ...
These ORNs then project their axons to the olfactory bulb. In the olfactory bulb, the ORNs synapse with termination in the glomeruli. [6] Each glomerulus receives input from olfactory receptor neurons expressing only one type of olfactory receptor. The glomerular activation patterns within the olfactory bulb are thought to represent the quality ...
The new study, published Monday in the journal JAMA Network Open, found microplastics in the olfactory bulbs of eight of 15 cadavers that ranged in size from 5.5 micrometers, or 0.000217 of an ...
