Abstract: A method and a device are used for carrying out measurements on cells located in a liquid environment. Each cell is positioned with an underside of its membrane on a surface having a channel running through it. A negative pressure is established to aspirate the cells. Each cell is electrically scanned via at least one electrode which is spaced apart from the cell. The negative pressure is preferably established in a pulse-like manner to rupture the membrane in such a way that the cell interior enclosed by the membrane is connected to the channel.

Abstract: The invention relates to a measuring arrangement for measuring electrical signals on biological membrane bodies, whereby an electroconductive acess into the membrane body is created by gap junction channels.

Abstract: The invention relates to novel heteroaryl carboxamides, processes for their preparation, and their use for producing medicaments for the treatment and/or prophylaxis of diseases and for improving perception, concentration, learning and/or memory.

Abstract: The invention relates to novel 1-aza-bicyclic N-biarylamides, methods for production and use thereof for the production of medicaments for the treatment and/or prophylaxis of diseases and for improving perception, concentration, learning ability and memory.

Abstract: The invention relates to novel 2-heteroarylcarboxamides, processes for their preparation, and their use for producing medicaments for the treatment and/or prophylaxis of diseases and for improving perception, concentration, learning and/or memory.

Abstract: The invention relates to novel bicylic N-arylamides, to a method for the production thereof, and to the use of the same for producing pharmaceuticals for the treatment and/or prophylaxis of diseases and for improving perception, power of concentration, learnig capacity and/or memory retention.

Abstract: A device for spatially separating a biochemical activity from a detection reaction that detects the biochemical activity. The device comprises a first membrane body comprising the biochemical activity, and a second membrane body comprising the detection reaction. The first and second membrane bodies each comprise lipid bilayers, wherein the first and second membrane bodies are connected by gap junctions.

Abstract: The invention relates to novel thiochromenones and processes for their preparation, to their use for the treatment and/or prophylaxis of diseases, especially for the treatment and/or prophylaxis of states of pain and neurodegenerative disorders.

Abstract: The present invention relates to a method for carrying out electrical measurements on biological membrane bodies, which are located on a substrate. The electrically conductive access to the membrane body, which is needed for the measurement, is made in situ by intense laser beams.
