A new approach for the whole-cell recording in slices is suggested as simpler and less expensive one than those known before. Electrophysiological characteristics of excitatory postsynaptic currents are obtained. Two types of glutamate receptors are shown to be involved. The kynurenic acid is proved to exert more prominent effect on the NMDA-receptor(More)
Trans-ACPD, a cyclic analogue of glutamate, has been studied for its influence on field potentials and excitatory postsynaptic currents (EPSCs) in the CA1 layer. Being applied in concentration 50 microM and above, trans-ACPD completely and reversibly inhibited excitatory postsynaptic field potentials but has no effect on EPSCs. Trans-ACPD in the same(More)
Quaternary ammonium salts (QAS), in which one of the substituent groups is aliphatic with a carbon chain consisting of more than 10 carbon atoms [I], are widely used among bactericidal drugs (for example, alkyl(Ci0_ Is)dimethyibenzylammonium chloride (Catamin AB)) [2]. QAS of various composition and functions, including bactericidal drugs produced abroad,(More)
