What insects have Octopamine neurotransmitters?
Examples of its neurotransmitter role are found in the firefly lantern and also possibly in the glandular lobe of the corpora cardiaca of locusts. Octopamine is also present in the haemolymph of cockroaches and locusts where it functions as a neurohormone, controlling the release of trehalose and lipid from fat body.
Where is octopamine found?
Octopamine is a chemical that is found in bitter orange and other plants, and in the human body in small amounts. It is also made in the lab.
Is octopamine a banned substance?
Octopamine is banned by the World Anti-Doping Agency (WADA) for use during competitive sports. Octopamine is found in some dietary supplements. However, the US Food and Drug Administration (FDA) cautions against its use and is investigating whether octopamine should be allowed in dietary supplements.
Is octopamine a neurotransmitter in invertebrates?
Octopamine has been proposed as a neurotransmitter/modulator/hormone serving a variety of physiological functions in invertebrates. We have initiated a study of octopamine in the fruit fly Drosophila melanogaster,which provides an excellent system for genetic and molecular analysis of neuroactive molecules.
Can we study octopamine immunoreactivity in Drosophila melanogaster?
We have initiated a study of octopamine in the fruit fly Drosophila melanogaster,which provides an excellent system for genetic and molecular analysis of neuroactive molecules. As a first step, the distribution of octopamine immunoreactivity was studied by means of an octopamine-specific antiserum.
Is octopamine involved in olfactory processes?
The localization of OA-IR cells in the cortex of the antennal lobe (AL cells) suggests a possible involvement of octopamine in olfactory processes.
What is the role of octopamine in visual sensitivity?
In Limulus,a role of octopamine in regulating visual sensitivity has been documented (Kass and Barlow, 1984), and, recently, OA-IRy has been observed in efferent fibers in the lateral optic nerves (Lee and Wyse, 1991). 5.
