A Study on Sound-card Recording Method for Electrophysiological Data

A commercially available sound card was used for the first time instead of the commonly used FM tape recorders or AD/DA cards in electrophysiological experiments for collecting continuous AC signals whose frequency is in the range of audio frequency. The sound card recording method is especially suitable for long time recording and large amount data storage due to the advantages of the modern PC and sound card, such as high capacity and compact harddisk or CD-r, a wealth of of software and easiness for use. Details were introduced for setting-up and experimental procedures. Moreover, the method was exemplified by recording of the response of gustatory sensilla on the ventral side of maxillary palp of cockroach, Periplaneta Americana to NaCl. The results showed that the method is simple , low cost and easy for data played back , data zoomed in/out and data storage. Discussions were given about its advantages and limitations.
