Olfaction in the Spruce Bark Beetle, Ips typographus [PDF]

, 2011
The bark beetle Ips typographus regularly kills spruce trees in the Palearctic. Spruces are colonized by means of attraction to an aggregation pheromone. Attraction is modulated by anti-attractive volatiles (NHV) from non-host plants.

Decoding the olfactory map through targeted transcriptomics links murine olfactory receptors to glomeruli

Nature Communications, 2022
Targeted spatial transcriptomics mapped olfactory receptor mRNAs to sections of the murine olfactory bulb to generate an interactive, statistical, 3D model of glomeruli locations and identify an ultra-sensitive receptor-odorant relationship.

Multimodal targets of (‐)‐α‐thujone mediating avoidance behavior of a stored‐products pest, Tribolium castaneum, in response to irritant stimuli

Pest Management Science, EarlyView.
We identified four kinds of target molecules against (‐)‐α‐thujone associating avoidance behavior in Tribolium castaneum, indicating multimodality. Abstract BACKGROUND The reciprocal evolutionary processes among phytophagous insects and host plants involve host shift in the herbivorous insects in response to defense chemicals, such as plant‐derived ...

Rapid encoding and perception of novel odors in the rat. [PDF]

PLoS Biology, 2008
To gain insight into which parameters of neural activity are important in shaping the perception of odors, we combined a behavioral measure of odor perception with optical imaging of odor representations at the level of receptor neuron input to the rat ...

Odorant Concentration Differentiator for Intermittent Olfactory Signals

, 2014
Animals need to discriminate differences in spatiotemporally distributed sensory signals in terms of quality as well as quantity for generating adaptive behavior.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Coding Odorant Concentration through Activation Timing between the Medial and Lateral Olfactory Bulb

Cell Reports, 2012
In mammals, each olfactory bulb (OB) contains a pair of mirror-symmetric glomerular maps organized to reflect odorant receptor identity. The functional implication of maintaining these symmetric medial-lateral maps within each OB remains unclear.

Structured odorant response patterns across a complete olfactory receptor neuron population

Neuron, 2019
Summary Odor perception allows animals to distinguish odors, recognize the same odor across concentrations, and determine concentration changes. How the activity patterns of primary olfactory receptor neurons (ORNs), at the individual and population ...

Functional Identification of a Goldfish Odorant Receptor

, 1999
The vertebrate olfactory system utilizes odorant receptors to receive and discriminate thousands of different chemical stimuli. An understanding of how these receptors encode information about an odorant's molecular structure requires a characterization ...
