An integrated system for recording and analyzing electrophysiological data from multiple channels is described. The system uses an MS-DOS microcomputer, a 16-channel amplifier, and multiple-tipped electrode arrays designed for use in intact and slice preparations. The system is designed for applications where the collection and analysis of multiple-channel electrophysiological data is desirable, including the construction of current source density (CSD) profiles from field potential data. The software incorporates on-line averaging, CSD and freeze-frame capabilities to guide the experiment in progress. Additional off-line analyses include multiple unit activity, power spectra, and automatic scans of data files for peak amplitude, area, latency, and slope within user-defined latency windows. All data and analyses can be exported to commercial statistical/graphical programs for the creation of publication-ready figures.
