The lability of the responses of mammalian central neurons to gamma-aminobutyric acid (GABA) was studied using neurons acutely dissociated from the CA1 region of the adult guinea pig hippocampus as a model system. GABA was applied to the neuronal somata by pressure ejection and the resulting current (IGABA) recorded under whole-cell voltage clamp. In initial experiments we examined several basi...

The paper presents a method of hydrogen sampling from an electrolysis cell for further analysis the composition generated gas. Solving problem sampling, system "electrolytic - separator gas pipette filled with distilled water" was used. ensures supply produced in to without mixing atmospheric gases. Sampling (oxygen) directly electrolyzer carried out evacuating storage tanks and connecting pipe...

The contribution of the dorsal nucleus of the lateral lemniscus (DNLL) to binaural processing was examined by recording single-unit activity in the rat's inferior colliculus before, during, and after a reversible block of the excitatory activity in DNLL by local injection of kynurenic acid. Recordings were made from the central nucleus of the inferior colliculus with glass micropipettes filled ...

A novel device of smart pipette has been suggested to extract and deliver plasma from whole blood in a disposable format. By operating an on-chip disposable micropump, approximately 30 μL of plasma was obtained from 100 μL of whole blood within 5 min without any external equipment for point-of-care blood analysis.
