Description and applications of a programmable stimulation system for electrophysiology, used as a computer peripheral.

An original programmable stimulation and data acquisition system of general interest for electrophysiology is presented. It can be used as a peripheral of any 12 (or more) bits mini- or microcomputer. With the software described it is possible to determine stimulation parameters automatically as a function of results obtained during the experiment or from the keyboard. Verification of parameters is carried out by permanent registration on the terminal screen, in numerical and analog form, and by facultative printout from the teleprinter. Two applications in electrophysiology are presented: the measurement of thresholds and the establishment of response curves.
