EAG Responses Increase of Antennae after a Single Pheromone Pulse

open access: yesNatural Product Communications, 2014
Increased behavioral sensitivity to the pheromone after brief exposure of the whole insect to the sex pheromone has been documented in antennal lobe neurons of Spodoptera littoralis . We investigated whether a brief stimulus of the major component of the

Antennal lobe representations are optimized when olfactory stimuli are periodically structured to simulate natural wing beat effects.

open access: yesFrontiers in Cellular Neuroscience, 2014
Animals use behaviors to actively sample the environment across a broad spectrum of sensory domains. These behaviors discretize the sensory experience into unique spatiotemporal moments, minimize sensory adaptation, and enhance perception.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

open access: yesAdvanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Functional differences between global pre- and postsynaptic inhibition in the Drosophila olfactory circuit

open access: yesFrontiers in Computational Neuroscience, 2012
The Drosophila antennal lobe is subdivided into multiple glomeruli, each of which represents a unique olfactory information processing channel. In each glomerulus, feedforward input from olfactory receptor neurons (ORNs) is transformed into activity of ...

Olfactory System Morphology Suggests Colony Size Drives Trait Evolution in Odorous Ants (Formicidae: Dolichoderinae)

open access: yesFrontiers in Ecology and Evolution, 2021
In social insects colony fitness is determined in part by individual worker phenotypes. Across ant species, colony size varies greatly and is thought to affect worker trait variation in both proximate and ultimate ways.

Olfaction in mosquitoes [PDF]

open access: yes, 2007
Female mosquitoes are vectors of diseases, affecting both livestock and humans. The host-seeking and identification behaviors of mosquitoes are mediated mainly by olfactory cues. The peripheral olfactory organs of mosquitoes which perceive olfactory cues
