A subset of octopaminergic neurons that promotes feeding initiation in Drosophila melanogaster.

PLoS ONE, 2018
Octopamine regulates feeding behavioral responses in Drosophila melanogaster, however the molecular and circuit mechanisms have not been fully elucidated.

RNA Interference of Dual Oxidase in the Plant Nematode Meloidogyne incognita

Molecular Plant-Microbe Interactions, 2005
RNA interference (RNAi) is a powerful tool for the analysis of gene function in model organisms such as the nematode Caenorhabditis elegans. Recent demonstrations of RNAi in plant parasitic nematodes provide a stimulus to explore the potential of using ...

Presence of octopamine and octopamine receptors in ganglia and tissues of Crassostrea virginica

The FASEB Journal, 2013
Octopamine (OA) a biogenic amine first identified in octopus is well studied in arthropods and gastropods being a neurotransmitter and hormone. OA has rarely been reported in bivalves. Using HPLC and ELISA we showed it present in ganglia and tissues of the oyster Crassostrea virginica, the ...

Fly Fighting: Octopamine Modulates Aggression

, 2008
SummaryThe genetics and neurobiology of Drosophila aggression are still poorly understood. A new study using an automated method to analyze one component of male fly aggression has shown that the biogenic amine octopamine plays a role in the modulation ...

Octopamine and ammonia plasma levels in hepatic encephalopathy

, 1977
It has been recently proposed that hepatic encephalopathy could be due to the accumulation of octopamine acting as a false neurotransmitter, and the increase of ammonia might reflect this accumulation.

Octopamine induces steady-state reflex reversal in crayfish thoracic ganglia

, 1996
1. This paper investigates the effect of octopamine on spontaneous and reflex motor output of crayfish leg motor neurons. Octopamine modulated spontaneous activity, both rhythmic and tonic, and dramatically modulated the pattern of reflex motor output ...

Octopamine receptors from the barnacle balanus improvisus are activated by the alpha2-adrenoceptor agonist medetomidine

, 2010
G protein-coupled octopamine receptors of insects and other invertebrates represent counterparts of adrenoceptors in vertebrate animals. The alpha(2)-adrenoceptor agonist medetomidine, which is in clinical use as a veterinary sedative agent, was ...

P-13 The Role of Octopamine in Selective Phonotaxis by Female Cricket Acheta Domesticus

, 2017
Female crickets respond phonotactically to the calls of conspecific males. Females’ response has been reported to be variable, ranging from unselective to selective of calls with varying syllable periods (30–90 ms).

Octopamine indirectly affects proboscis extension response habituation in Drosophila melanogaster by controlling sucrose responsiveness

, 2014
Octopamine is an important neurotransmitter in insects with multiple functions. Here, we investigated the role of this amine in a simple form of learning (habituation) in the fruit fly Drosophila melanogaster.

The effect of a selective octopamine antagonist, epinastine, on pharyngeal pumping in Caenorhabditis elegans

, 2010
This paper investigates the effect of epinastine, a selective octopamine antagonist in invertebrates, in Caenorhabditis elegans. Specifically, its ability to block the inhibitory action of octopamine on C. elegans-isolated pharynx was assayed.
