In fact, when an olfactory sensory neuron expressing a particular receptor gene dies and a new neuron expressing that same gene matures, the new neuron's axons plug in to the same group of olfactory bulb neurons that its predecessor did.

SpatialDE automatically identifies sub-structures (middle), and links these to genes that depend on spatial location (right) in mouse olfactory bulb data from Stahl et al 2016.

In rats, olfactory bulb neurons use simple «linear summation'to make sense of fluctuating odor inputs from the surrounding environment...

(And perhaps not coincidentally, researchers have found that people who are depressed often have smaller olfactory bulb volumes and decreased senses of smell compared to nondepressed subjects.)

That makes human brains different from those of rodents, nonhuman primates and other mammals, which constantly make new nerve cells, or neurons, in the odor - processing olfactory bulb.

A unique form of carbon dating, made possible by the Cold War, suggests that new neurons rarely survive in the human olfactory bulb after birth

Using microelectrodes, the researchers recorded the electrical activity of pheromone - sensitive interneurons in male American cockroaches that relay signals of female - producing sex pheromones in the antennal lobe (functional homolog to the mammalian olfactory bulb) to higher - order centers.

But even more interesting was the space allocated to two huge olfactory bulbs, which were almost as large as the rest of Sue's brain.

Experiments by the CSHL team explain how these components of the mouse olfactory bulb estimate the total activity across the bulb.

Once believed to lack a sense of smell, dragonflies and damselflies, such as Ischnura elegans (pictured), possess olfactory bulbs in their antennae that may help them track prey.

We also observed some YFP - labeled cells in the epidermis, forebrain, and occasionally olfactory bulb (Figure 4E and 4F and unpublished data).

Olfactory bulb removal eliminated maternal behavior in lactating and in virgin mice.

Olfactory bulb tissue sections of isochronic (control) and heterochronic old (Het - O) mice were stained by immunofluorescence for BrdU (replicating cell marker) and neuronal neurons (NeuN) to detect newborn neurons.

Furudono, Y.; Cruz, G.; Lowe, G. (2013) Glomerular input patterns in the mouse olfactory bulb evoked by retronasal odor stimuli.

Dogs are believed to have 40X olfactory bulbs than we do.

The dog for example has a bigger olfactory bulb than the human because they use scent to hunt for food.

Early - life stress disrupts attachment learning: The role of amygdala corticosterone, locus ceruleus corticotropin releasing hormone, and olfactory bulb norepinephrine

Whether or not humans possess an accessory olfactory bulb or have tacked pheromonal signaling onto the list of the main olfactory system's chores remains a matter of debate.

Compared with control subjects, he found, people suffering from depression were less able to detect weak smells; MRI scans revealed that they had smaller olfactory bulbs, the brain structures involved in odor perception.

A cross section of the mouse olfactory bulb.

Olfactory bulbs are part of the limbic system and directly connect to the areas of the brain that process emotion and learning.

The phenomenon has something to do with the olfactory bulb in the brain's limbic system and how it forever links the scent of soap and freshly - cut lavender to the security of your grandmother's guest room.

They say that smell is most powerful sense for bringing back memories — something about the olfactory bulb in the brain's limbic system and how it forever links the scent of freshly - cut lavender to the security of your grandmother's guest room.

With our unrivalled breadth of taste systems, Kerry can tackle the whole taste experience, from the first visual cues through to the satisfying sensation after the last traces of aroma reach the olfactory bulb.

Green is electroporated neuroblasts born in the sub ventricular zone that migrated into the olfactory bulb.

Samuel Weiss, director of the Hotchkiss Brain Institute at the University of Calgary, and his colleagues reported that nerve cells sprouted in the olfactory bulb, the seat of the sense of smell, and in the hippocampus, the brain's memory bank.

To find these patterns, researchers used to expose rats to an odor for 45 minutes — an unnaturally long time — then kill them and look for changes in the uptake by the olfactory bulb of a labeled form of glucose, which indicates neuronal activity.

This pattern is processed and remembered by neural circuits in the olfactory bulb and olfactory cortex.

The brain (specifically, the olfactory bulb and olfactory cortex) then looks at the combination of sensory neurons activated at any given time and interprets that pattern in the context of previous patterns that have been experienced and other kinds of available information.

The neurons send their signals to the brain's olfactory bulb, where each of thousands of little clusters of neurons called glomeruli receives input from olfactory neurons with just one receptor type.

Rubin tried the technique on rats, removing or thinning the part of the skull lying over their olfactory bulbs, then measuring the pattern of optical signals when the animals were exposed to different odors.

So if you look at whole brains, the bulbs look like these tiny afterthoughts; if you look at a mouse or a rat, the olfactory bulb seems quite big.

Compared to the olfactory bulbs [the first stop for smell signals in the brain], the rest of the human brain is very large.

Agalliu also found that Th17 cells induced by strep opened the BBB only in certain spots: Since strep enters the body through the nose, it made sense that he saw the BBB was pierced near the olfactory bulb, the structure in the front of the brain that processes odors.

«If somebody has very mild Alzheimer's and dies,» Devanand says, «on autopsy, we will see the pathology of Alzheimer's — the tangles and plaques — in the olfactory bulb.»

It goes from the nose to the olfactory bulb and then directly from there to the olfactory [processing area] but also to places like the amygdala and the hippocampal formation, which are involved in emotion and memory.

The researchers tested samples of brain cells from people with MS and healthy control subjects and found evidence of the virus in the olfactory bulb in both groups.

The prospects for using them in treatments have been limited, however, because their only sources were thought to be the lining of the nose and the olfactory bulb in the brain where smell signals are processed.

Biopsies from the human nose lining have only yielded tiny numbers of OECs, and obtaining them from the olfactory bulb would be invasive and potentially dangerous.

The virus appears to invade the brain by infecting a type of glial cell called olfactory ensheathing cells (OECs), which nourish smell - sensing neurons and guide them from the olfactory bulb to their targets in the nervous system.
