A fluorescence histochemical technique with glyoxylic acid has been employed to locate the catecholamines noradrenalin and dopamine and the indolealkylamine 5-hydroxytryptamine (5HT) in the brains of a number of genera of cephalopods.
cephalopod brain the fluorescence is not uniformly distributed. The possibility that noradrenalin, dopamine and 5HT have specific neurotransmitter functions is discussed. INTRODUCTION There are a number of reports of the presence of possible neurotransmitters in the cephalopod brain (see, for example, Tansey (I)).

B, Biological Sciences,(), Online publication date: Nov Evidence is presented from fluorescence histochemistry studies that blood vessels in the viscera of Octopus vulgaris are innervated by nerve fibres containing catecholamines.
This, with other evidence, suggests that cephalopods, like vertebrates, may be capable of regulating their peripheral vasculature by central neural by: In cephalopods, there is ultrastructural evidence that most, if not all, synapses in the CNS are chemical rather than electrical (Gray & Young, ).
However, it must be emphasised that the chemical identity of the transmitter is not known for any synapse in the cephalopod by: Summary. The cephalopod nervous system is the most complex of any invertebrate nervous system.
Although species-specific differences exist, its high level of complexity almost certainly is due to the cephalopods’ very active, fast-moving, predatory life style, and their complex behavior and extreme flexibility of response to different environmental by: The detailed distribution of aminergic fluorescence in the brain of Octopus has been described by Tansey ().
There are remarkably high quantities of these biogenic amines localized in the posterior salivary glands and the buccal lobe region of the brain which innervates them (Arluison and Ducros, ; Martin and Barlow, ;Matus, ).Cited by: In the brain and sense organs cholinergic, aminergic, serotonergic and glutamatergic systems seem to be the most important.

There is an excellent review on the physiology of cephalopod vision by Messenger (), and a brief account of research methods by Daw ().Cited by: Fluorescence is the result of a three-stage process that occurs in certain molecules (generally polyaromatic hydrocarbons or heterocycles) called fluorophores or fluorescent dyes (Figure 1).A fluorescent probe is a fluorophore designed to respond to a specific stimulus or to localize within a specific region of a biological specimen.
The Fluorescence Process. The fluorescence process can be broken down into three phases 1. Excitation - absorption of light of an appropriate wavelength by fluorophore 2. Excited state - fluorophore undergoes vibrational and conformational changes 3.
Emission - photon of light is emitted. The fluorescence process is cyclical therefore a File Size: KB. : Fluorescence and Phosphorescence (Analytical Chemistry by Open Learning) (): Rendell, David: BooksCited by: Cephalopod molluscs, the squids, cuttlefishes and octopuses, are remarkable among invertebrates for their complex behaviour, elaborate sense organs and the well-developed brain, which has been the subject of many investigations from the last century to the pre- sent day6'7'18'29'Cited by: Full Text; PDF ( K) PDF-Plus ( K) Citing articles; The cephalopod specialties: complex nervous system, learning, and cognition 1.
