On-line analysis of neuromuscular bioelectric potentials

Computerized estimation of spontaneous and evoked acetylcholine release at the neuromuscular junction

A new and automated on-line analysis of the parameters related to the neuromuscular activity is shown. The procedure used to obtain in real time the statistical evaluation of the recorded electrical signals is presented and discussed. The hardware is composed of a PDP-11/73 microcomputer equipped with an analog input/output board. The software is written principally in FORTRAN 77 and also uses MACRO/ASSEMBLY language.

Distributed computer system for capture, analysis and display of biological data

A distributed real-time computer system has been developed to automate the collection, analysis and display of biological (pharmacological) data. It comprises a series of laboratory interface devices (CED 1401/1609) connected to a micro-VAX II via multiple IEEE-488 buses. The micro-VAX II is integrated to the main site computers using Ethernet running DECnet. The micro-VAX II system supports a multi-user, multipreparation and multitasking environment and it provides rapid transfer, storage, analysis and display of data. The system saves the pharmacologists from the manual analysis of their data, typically saving them four days of analysis per experiment and has improved both the quality of data detected and their subsequent analysis. Also, the development of a standard data capture procedure on common hardware along with the modular design of application software has almost quartered project development times.

Automated on-line system for the acquisition and computation of skeletal muscle end-plate derived signals

A low-cost computerized system to collect electrophysiological data, either off- or on-line from in vitro preparations treated with different pharmacological agents, is discussed. The block diagrams of the hardware configuration and of the logical procedures are illustrated and discussed.

A computerized approach to the collection and analysis of cardiac action potentials

A description is given of a microcomputer system for the collection and storage of cardiac action potentials. The equipment required is commercially available and easy to use. Analysis of the data is performed off-line with a mainframe computer. A description of the software used for both data collection and data analysis is given.
