V návaznosti na výzkum botaniků a malakozoologů se na unikátních prameništních mokřadech Západních Karpat rozběhlo v posledních letech také intenzivní studium vodních bezobratlých zaměřených rovněž na skupiny mikroskopických korýšů - lasturnatek (Ostracoda) a plazivek (Harpacticoida). Podařilo se nám objasnit jejich distribuci na prameništích, nalézt 8 nových druhů pro Českou a Slovenskou republiku a rozšířit znalosti o jejich ekologii., In connection with research by botanists and malacozoologists at unique spring areas in Western Carpathian marshland, intensive study has taken place over the last few years into water invertebrates and groups of microscopic crustaceans - ostracodes (Ostracoda) and Harpacticoida. We have succeeded in clarifying their distribution in the spring areas, finding eight new species for the Czech and Slovak Republics and expanding knowledge of their ecology., and Marie Zhai, Dana Hřívová, David Výravský.
The miniature excitatory postsynaptic currents (MEPCs) of the muscle cells of the earthworm Lumbricus terrestris were recorded by glass microelectrodes. In a single synaptic zone, three types of MEPC were recorded: a fast single-exponential type that decayed with τ=0.9 ms, a slow single-exponential with τ=9.2 ms and a two-exponential MEPC with τ = 1.3 and 8.5 ms, respectively. The muscle cells of earthworms contain populations of yet-unidentified ionic channels that might be different from the common nicotinic and muscarinic groups of acetylcholine receptors, since these MEPCs are not sensitive to d-tubocurarine, atropine, benzohexonium or proserine. Alternatively, besides ACh receptors, the membrane may contain receptors for an other yet-unidentified excitatory transmitter., E. M. Volkov, L. F. Nurullin, E. Nikolsky, F.
