A system named Automated Spindle Analyzer (ASPA), which automatically detects sleep spindles and measures the mean amplitude, the mean frequency, the duration and the time of occurence of each spindle in real time, is described. It can also calculate the means, standard deviations and distributions of each parameter across the recording. Furthermore, it is possible to control experiments concurrently with analyzing sleep spindles by the system. Agreement between spindle detections obtained by visual scoring method and by the ASPA was relatively high; approximately 90%. The ASPA has advantages of low cost, portability and self-sufficiency. The utility of this system thus recommends it for the analysis of sleep spindles in laboratories and various other circumstances as well.
