... Neurotransmitters Receptors Howard Hughes Medical Institute http://dx.doi.org/10.13039/100000011 The fruit fly Drosophila melanogaster is perhaps the leading candidate in which to study the comprehensive structure and function of the brain, and the mechanistic basis of behavior. The fly...

... predominates, enabling the efficient mobilization or storage of energy in a negative or positive energy balance, respectively. The release of noradrenaline from the sympathetic nervous system activates lipolysis in a depot-specific manner by initiating the canonical adrenergic receptor–G s -protein–adenylyl...

... in the gilthead sea bream ( Sparus aurata ). Pituitary and plasma arginine vasotocin (AVT) and isotocin (IT) levels, as well as hypothalamic pro-vasotocin (pro-VT) and pro-isotocin (pro-IT) mRNA expression levels, were analysed. In addition, the mRNA levels of three receptors, AVTR type V1a2, AVTR type V2 and ITR...

...R. E. Sandeman; D. C. Sandeman ABSTRACT The antennules of the crayfish Cherax destructor can first be observed as antero-laterally located lobes in embryos that have reached the 50 % stage of development. Clusters of cells that are probably the olfactory receptor neurones (ORNs) appear...

... suggests that ANF is synthesized in toad lungs and atria. Characterization of toad lung receptors by a competitive binding assay demonstrated three different subtypes of ANF receptors: the guanylyl cyclase (GC) receptors, GC-A and GC-B, as well as clearance (C) receptors. We conclude that the toad Bufo...

... in different preparations were highly reproducible. Both GABA A and GABA B receptors were reversibly activated by selective agonists and inhibited by specific antagonists. The actions of GABA were potentiated by benzodiazepines, competitively antagonised by bicuculline (a selective GABA A antagonist...

...F. Dubas ABSTRACT To characterize the receptors for putative amino acid neurotransmitters present on the dendritic arborizations of flight motoneurones in Locusta migratoria , the effects of pressure applications of glutamate, γ-aminobutyric acid (GABA), aspartate, taurine, glycine and cysteine...

... to procumbent feathered hairs. Physiological recordings from the sensory axons of the flagellar nerve allowed the characterization of the sensory hair response to displacement. Recordings were also made from slowly adapting receptors, sensitive to bending the flagellum in particular directions, but not related...

... by hexamethonium. Despite testing a number of known cholinergic and histaminergic agents, no effective agonist for histamine was found. The results indicate the existence of a novel class of histamine-sensitive receptor with nicotinic features. In addition the unusual effects of a traditional Hl agonist, 2...

...Brian Phillip Oldfield ABSTRACT One of the fundamental problems in auditory research is the origin of the frequency selectivity of auditory receptors. Horridge (1960) demonstrated that the auditory interneurones in locusts were tuned to different sound frequencies, thus suggesting that the auditory...
