In each case the number of compartments of the CSD model matched the number of recording positions, and the length of the modeled antenna was kept identical by extending the first and the last compartment when required. The CSD was set to 1 light gray in the proximal compartment 8 or to 2 dark gray in one half of the proximal compartment: either the proximal half 9 or the central half The antennal neural tissues are ideal generators of field potentials Despite of differences due to the propagation of the LFP signal through the brain tissue and of the EAG signal through the insect cuticle, the main principles are similar. Josiah Macy Foundationed. A EAG response was recorded at four antennal positions of the antenna of a female C.

    Two main types of antennal recordings were used over the past 60 years for this purpose Olsson and Hansson, : electroantennography EAG Schneider, abwhich consists in recording field potentials across the antenna, and single-sensillum recording SSR Einzelnen, ; Schneider and Boeckh,which consists in recording the spiking activity elicited by the ORNs of a single sensillum.

    This paper details the use of a similar approach adapted to the study of olfactory responses within insects with bulbous antennae. However, this compound elicited only a low EAG response when recorded with a distal electrode Light et al.

    Trends Genet. The technique was invented in by German biologist Dietrich Schneider [1] and shares similarities with electro-olfactography.

    Synchronous voltage changes by both the FID and the antenna indicate olfactory sensitivity by the insect to the compound eluting at that particular retention time.

    How the antennal tissue differs from brain tissues The classical models of CSD analysis required a uniform resistivity of the extracellular medium in every direction. The tool provides the precision and control needed for scoring the pipette tip at a specific, desired location. If the activated ORNs are distributed in an area smaller than a compartment of the model cases 2, 3, and 6then the model detects a current source in this compartment and mistakenly estimates a current source with a reverse polarity in the neighboring compartments.

    The FID peaks of these three compounds were identified by matching their retention times to those of commercially-available versions of the same compounds injected into the GC.

    The most common and most generally useful detector is the flame ionization detector FID which is sensitive to all organic molecules.

    However, this study showed that CSD analysis can be misled in reporting inexistent current sources due to an insufficient spatial sampling or to an approximation of the funiculus geometry. Elucidating the neuronal architecture of olfactory glomeruli in the Drosophila antennal lobe. Commonly, tungsten wires that have been chemically sharpened are inserted into a single neuron in the antenna.
