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.

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.

Albeanu and colleagues, including Arkarup Banerjee and Fred Marbach, graduate students in the Watson School for Biological Sciences at CSHL and co-first authors of the Neuron paper, conducted experiments in living animals that revealed a mechanism for adjusting olfactory signal gain.

The team was able to view the responses of tens of neurons at a time to signals arriving in the olfactory bulb from the mouse's odor detectors, called olfactory sensory neurons, located in the nose.

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.

Pheromones are detected by the so - called vomeronasal organ, which sits in the nasal cavity and sets off a cascade of nerve signals that ends in the accessory olfactory bulb, the organ that processes pheromones.

Lawrence Katz of the Duke University Medical Center and his colleagues discovered that once signals reach the accessory olfactory bulb they are mapped out into distinct patterns of nerve cell activity that vary according to the traits that enable a mouse to identify desirable mates, such as species and sex.

«However,» the author adds, «although our results suggest that rhesus macaques are able to distinguish between in - group and out - group individuals based on olfactory cues alone, the recognition of conspecifics might be a more multimodal process also including visual cues or a combination of olfactory and auditory signals.

By recording neuronal activity in the input and output layers of the olfactory bulb, as well as feedback from olfactory cortical areas and neuromodulatory signals, Albeanu and his team aim to understand computations the bulb performs and how this information is decoded deeper in the brain.

Thus, we concluded that Acks could be utilized as a marker of neural activity that occurred 30 to 60 min before in the brains of Japanese honeybees, although we could not detect the spotted signal in the antennal lobes (ALs, primary olfactory center), suggesting that Acks, like kakusei, is not useful for detecting neural activity in the ALs (data not shown).

Canonical Wnt signaling promotes the proliferation and neurogenesis of peripheral olfactory stem cells during postnatal development and adult regeneration.

The role of Drosophila mushroom body signaling in olfactory memory.

A new study from the labs of Yiqun Yu and Hongmeng Yu (Fudan University, Shanghai, China) sought to uncover the role of Notch signaling in the regulation of olfactory epithelium (OE) progenitor / stem cells.

We included genes with and without a known function in olfactory and vomeronasal signaling that cover the whole range of expression values observed (Table S1).

This project provides the opportunity to record intracranial LFP signals from the olfactory as well as the limbic regions of the human brain while patients participate in various olfaction - based behavioral paradigms.

Additionally, most of the cancer cell lines expressing olfactory receptors express the effectors necessary for OR - mediated signal transduction.

Although insula activations are commonly observed during odor perception [33], in the present study these activations are very likely not caused by an olfactory component of the chemosensory anxiety signals.

Background: Olfactory receptors (ORs) recognize odorant molecules and activate a signal transduction pathway that ultimately leads to the perception of smell.

How aromatherapy works When you sniff an essential oil, your olfactory bulb fires off signals to the limbic system, the part of the brain that controls emotions — that's how scents affect your mood.

Although the production of chemical signals, their perception through olfactory processes, and the behavioral response to these signals plays a central role in domesticated cat communication and behavior (especially social behavior), the function, scope and importance of these abilities are often not given the same level of attention dedicated to other domesticated species (e.g. dogs or pigs), which may lead some to erroneously underestimate the significance of this communication modality in cats.

The received notion, as I understand it, is that molecules of a particular oderant have a unique shape that will latch on to some of the five or six million receptors in our olfactory area and thus trigger signals that cause the brain to register a particular smell.

In addition to employing the olfactory effect of greenery, this homeowner likes to pepper her place with candles that emit season - signalling scents, such as fig and redcurrant.
