Immunocytochemical Mapping of an RDL-Like GABA Receptor Subunit and of GABA in Brain Structures Related to Learning and Memory in the Cricket Acheta domesticus

摘要: The distribution of putative RDL-like GABA receptors and γ-aminobutyric acid (GABA) in the brain adult house cricket Acheta domesticus was studied using specific antisera. Special attention given to structures known be related learning memory. main immunostaining for receptor observed mushroom bodies, particular upper part body peduncle two arms posterior calyx. Weaker detected distal α β lobes. dorso- ventrolateral protocerebrum neuropils appeared rich receptors. Staining also glomeruli antennal lobe, as well ellipsoid central complex. Many neurons clustered groups exhibit GABA-like immunoreactivity. Tracts that were strongly immunostained innervated both calyces lobes bodies. body, immuno- reactivity. data demonstrated a good correlation between prominent subunits, areas bodies lobes, underlines importance inhibitory signals information processing these major integrative centers insect brain.
