Abstract : This system allows the collection and display of neurophysiological data during the time the experiment is being run. The system was initially designed for collecting both intracellular and extracellular evoked-response information. A 25-ms sample from two channels of analog information is taken periodically and processed. The two channels of information are sampled as closely to simultaneously as the instruction timing will allow (using an LSI-11, 30 microsec). The operating mode and intersample period may be controlled by the computer through a user-supplied time interval. It also may be driven by a Schmitt trigger through timing pulses during an experiment or from a recording. (Author)
