Briefly, two major neuronal cell types co-exist: the mechanoreceptors which are sensors of touch perception and proprioception [8] and the chemoreceptors which express odor-binding proteins but without any clearly demonstrated function to date [9], [5].
(F ) Average H2BE level within neurons expressing odor-stimulated or control ORs (n = 20 60).
For example, individual olfactory neurons express multiple odor receptors, multiple heterotrimeric G protein α subunits, multiple GCs and they display a wide range of other, often-novel, mechanisms for signal integration within individual neurons.
Some of the sensory hairs (slender) on the anterior wing margin are chemoreceptors that express odor-binding proteins.
For populations of principal cells coherent to theta4-12 Hz, beta15-25 Hz, low gamma35-55 Hz, and high gamma65-90 Hz during correct trials, we calculated the information for positions, odors, and odor-position conjunctions expressed in their spiking activity.
The apical dendrite extends radially and arborizes in single glomerulus where it receives primary input from olfactory sensory neurons that express the same odor receptor.
Social parasites may then passively acquire (camouflage) and/or actively synthesize (mimicry) the recognition cues of the host colony, therefore expressing a new odor more similar to that of their host colony [49].
Optogenetic activation of TH GAL4 neurons expressing P2X2 during odor presentation formed aversive memory in single flies [91].
We found several genes that were differentially expressed in response to cactus odor.
In most cases, only one canonical odor receptor is expressed per olfactory sensory neuron pair (Fishilevich et al., 2005; Kreher et al., 2005).
