Dopaminergic modulation of odor responses by local interneurons in the olfactory bulb [PDF]

, 2011
The olfactory bulb is one of the few regions in the brain where dopamine is provided locally by an intrinsic population of GABAergic interneurons but their role in processing of sensory information remains ambiguous.

Background Odors Modulate N170 ERP Component and Perception of Emotional Facial Stimuli

Frontiers in Psychology, 2018
Successful social interaction relies on the accurate decoding of other peoples’ emotional signals, and their contextual integration. However, little is known about how contextual odors may lead to modulation of cortical processing in response to facial ...

A Mathematical Model of the Olfactory Bulb for the Selective Adaptation Mechanism in the Rodent Olfactory System. [PDF]

PLoS ONE, 2016
To predict the odor quality of an odorant mixture, the interaction between odorants must be taken into account. Previously, an experiment in which mice discriminated between odorant mixtures identified a selective adaptation mechanism in the olfactory ...

Optimizing odor-baited trap methods for collecting mosquitoes during the malaria season in The Gambia. [PDF]

, 2009
BACKGROUND: Baited traps are potential tools for removal or surveillance of disease vectors. To optimize the use of counter-flow traps baited with human odor (nylon socks that had been worn for a single day) to capture wild mosquitoes in the Gambia ...

Enhanced odor discrimination and impaired olfactory memory by spatially controlled switch of AMPA receptors [PDF]

, 2005
Genetic perturbations of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptors (AMPARs) are widely used to dissect molecular mechanisms of sensory coding, learning, and memory.

Familiar-odor-biased PNs and LNs are novelty and familiarity detectors.

, 2022
PNs and LNs display initial response biases to the two test odors Hex and Oct prior to familiarization (A1, A2). Some neurons respond more strongly to Oct than to Hex, i.e., data points above the diagonal line; some neurons respond more strongly to Hex ...
