Maturation of odor representation in the honeybee antennal lobe

open access: yesJournal of Insect Physiology, 2005
The antennal lobe (AL) is the first center for processing odors in the insect brain, as is the olfactory bulb (OB) in vertebrates. Both the AL and the OB have a characteristic glomerular structure; odors sensed by olfactory receptor neurons are represented by patterns of glomerular activity.

Antennal lobe organisation in ant, Oecophylla smaragdina: A Golgi study

open access: yesJournal of Biosciences, 2021
Antennal lobes (AL) are the primary olfactory centres of the insect brain, the organisation of which reflects the chemosensory repertoire of the insect. The sensory neurons from the antenna, local neurons (LNs), and projection neurons (PNs) constitute the neuropilar organisation of the AL, which often varies according to the ecology and behaviour of ...

Optically Bound Rapid Plasmonic Nanorod Dimers: Anisotropic Dynamics Driven by Light‐Fluidic Cooperation

open access: yesLaser &Photonics Reviews, EarlyView.
Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

Olfactory learning without the mushroom bodies: Spiking neural network models of the honeybee lateral antennal lobe tract reveal its capacities in odour memory tasks of varied complexities.

open access: yesPLoS Computational Biology, 2017
The honeybee olfactory system is a well-established model for understanding functional mechanisms of learning and memory. Olfactory stimuli are first processed in the antennal lobe, and then transferred to the mushroom body and lateral horn through dual ...

Descriptions of new luperine genera and species from Mexico : with keys to related taxa (Coleoptera: Chrysomelidae: Galerucinae) [PDF]

open access: yes, 1998
The section Scelidites ofthe subtribe Luperina is diagnosed and described. A key is provided to separate the genera within this section. Cyphotarsis Jacoby is reduced to a junior synonym of Metacoryna Jacoby.

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

open access: yesOikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Searching for learning-dependent changes in the antennal lobe: simultaneous recording of neural activity and aversive olfactory learning in honeybees

open access: yesFrontiers in Behavioral Neuroscience, 2010
Plasticity in the honeybee brain has been studied using the appetitive olfactory conditioning of the proboscis extension reflex, in which a bee learns the association between an odor and a sucrose reward.
