Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Individual neurons confined to distinct antennal-lobe tracts in the heliothine moth: morphological characteristics and global projection patterns

Frontiers in Neuroanatomy, 2016
To explore fundamental principles characterizing chemosensory information processing, we have identified antennal-lobe projection neurons in the heliothine moth, including several neuron types not previously described.

Gain modulation and odor concentration invariance in early olfactory networks.

PLoS Computational Biology, 2023
The broad receptive field of the olfactory receptors constitutes the basis of a combinatorial code that allows animals to detect and discriminate many more odorants than the actual number of receptor types that they express.

Structure and function of the moth mushroom body [PDF]

, 2006
The mushroom bodies are paired, high-order neuropils in the insect brain involved in complex functions such as learning and memory, sensory integration, context recognition and olfactory processing.

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

Integrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

Antennal-Lobe Organization in Desert Ants of the Genus Cataglyphis [PDF]

Brain, Behavior and Evolution, 2011
Desert ants of the genus Cataglyphis possess remarkable visual navigation capabilities. Although Cataglyphis species lack a trail pheromone system, Cataglyphis fortis employs olfactory cues for detecting nest and food sites. To investigate potential adaptations in primary olfactory centers of the brain of C.

Spatial Representation of Odorant Valence in an Insect Brain

Cell Reports, 2012
Brains have to decide whether and how to respond to detected stimuli based on complex sensory input. The vinegar fly Drosophila melanogaster evaluates food sources based on olfactory cues.

A new species of Stenorrhachus McLachlan from Chile (Neuroptera: Nemopteridae) with biological notes [PDF]

, 2012
A new species of Stenorrhachus (McLachlan), S. chilensis (Neuroptera: Nemopteridae), is described from Chile with biological observations of Stenorrhachus walkeri (McLachlan). A key to the two species is provided as well as diagnoses of the adults and of

First Zoeal Stage of the Snapping Shrimp Alpheus Fabricius, 1798 (Caridea: Alpheidae): New Description of Alpheus bouvieri A. Milne‐Edwards, 1878 and Literature Review

Acta Zoologica, EarlyView.
ABSTRACT Based on adult morphological characters, the more than 300 species of Alpheus were divided into seven informal species groups, but some groups are not supported by molecular data. The aim here was to describe the zoea I of Alpheus bouvieri, and to do a review of the larval descriptions available in the literature, analysing whether the ...

Spatio-temporal activity patterns of odor-induced synchronized potentials revealed by voltage-sensitive dye imaging and intracellular recording in the antennal lobe of the cockroach

Frontiers in Systems Neuroscience, 2012
In animals, odor qualities are represented as both spatial activity patterns of glomeruli and temporal patterns of synchronized oscillatory signals in the primary olfactory centers.
