Topics in Cognitive Science, EarlyView., 2023 Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

Structural Features of an OR37 Glomerulus: A Comparative Study
Frontiers in Neuroanatomy, 2017 In the olfactory bulb (OB) a sophisticated neuronal network mediates the primary processing of sensory information and extensive investigations over the past decades have greatly improved our understanding of the morphology and neuronal organization of ...

Frontiers in Ecology and Evolution, 2022 In moths, mate finding relies on female-emitted sex pheromones that the males have to decipher within a complex environmental odorant background. Previous studies have shown that interactions of both sex pheromones and plant volatiles can occur in the ...

Oscillatory Sequences of Firing in the Locust Olfactory System: Mechanisms and Functional Significance [PDF]
, 1999 What neural codes does the brain use to represent and process sensory information? Stimulus-evoked oscillatory synchronization of neuronal activity has been observed in many systems, yet the possible functions of such rhythmic synchronization in neural ...

Silencing of Odorant Receptor Genes by G Protein βγ Signaling Ensures the Expression of One Odorant Receptor per Olfactory Sensory Neuron [PDF]
, 2014 SummaryOlfactory sensory neurons express just one out of a possible ∼1,000 odorant receptor genes, reflecting an exquisite mode of gene regulation. In one model, once an odorant receptor is chosen for expression, other receptor genes are suppressed by a ...

Tuning Insect Odorant Receptors [PDF]
Frontiers in Cellular Neuroscience, 2018 Among the insect olfactory receptors the odorant receptors (ORs) evolved in parallel to the onset of insect flight. A special property of this receptor type is the capability to adjust sensitivity of odor detection according to previous odor contacts.

Sequence comparisons of odorant receptors among tortricid moths reveal different rates of molecular evolution among family members. [PDF]
PLoS ONE, 2012 In insects, odorant receptors detect volatile cues involved in behaviours such as mate recognition, food location and oviposition. We have investigated the evolution of three odorant receptors from five species within the moth genera Ctenopseustis and ...

The narrowing olfactory landscape of insect odorant receptors
Frontiers in Ecology and Evolution, 2015 The molecular basis of odorant detection and its corollary, the task of the odorant receptor, are fundamental to understanding olfactory coding and sensory ecology.

Identification of odorant-receptor interactions by global mapping of the human odorome.
PLoS ONE, 2014 The human olfactory system recognizes a broad spectrum of odorants using approximately 400 different olfactory receptors (hORs). Although significant improvements of heterologous expression systems used to study interactions between ORs and odorant ...

Characterization of an enantioselective odorant receptor in the yellow fever mosquito Aedes aegypti. [PDF]
PLoS ONE, 2009 Enantiomers differ only in the left or right handedness (chirality) of their orientations and exhibit identical chemical and physical properties. In chemical communication systems, enantiomers can be differentially active at the physiological and ...
