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
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 ...
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 latest research looked at a part of the brain called the olfactory bulb, which processes information about smell. Humans have two olfactory bulbs, one above each nasal cavity. Humans have two ...
The olfactory sensory system is unique since the neurons in the olfactory bulb send their axons directly to the olfactory cortex, rather than to the thalamus first. Olfaction is also the only sense that is represented by the ipsilateral side of the brain. Damage to the olfactory bulb results in a loss of olfaction (the sense of smell).
Olfactory glands, also known as Bowman's glands, are a type of nasal gland situated in the part of the olfactory mucosa beneath the olfactory epithelium, that is the lamina propria, a connective tissue also containing fibroblasts, blood vessels and bundles of fine axons from the olfactory neurons.
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 ...
This allows the granule cells to regulate the processing of the sensory input in the olfactory bulb. [21] The olfactory bulb transmits smell information from the nose to the brain, and is thus necessary for a proper sense of smell. Granule cells in the olfactory bulb have also been found to be important in forming memories linked with scents. [22]
