You can download the trial version of SleepSign software which contains all analysis features of the commercial version.
Please contact us to request a trial version.
The SleepSign data acquisition program can record up to 16 channels with the standard hardware setting. With an additional hardware; channel expansion accessory, you can record up to 32 channels. Therefore, if you record two channels (EEG and EMG) from each animal, you can record up to eight animals with the standard hardware setting, and 16 with the channel expansion accessory.
If you add on video recording capability, you can record/playback up to four animals using a multiplexer. (SleepSign supports multiplexers which divide the image into four parts). You can record up to 16 channels of waveform data when you record video, too.
The maximum file size for raw data is 2 GB. Recording as many as 32 channels will result in a very large data size. Refer to the following table “Data Size of Raw Data” to see if the combination of “sampling frequency,” “number of channels,” and “recording time” is feasible for your experiment. If you add the video recording feature, the video data size will be approximately 400 MB/hour or 10 GB/day in addition to the raw data files. The video file format is "AVI (Microsoft MPEG4-V2)". Videos should be saved to the internal HDD during recording. In addition, a storage medium (external HDD, DVD, etc.) with a size that can withstand such storage is required.
Although the majority of our clients use SleepSign for studies of rodents, you can apply it to any kind of animal as long as EEG and EMG are available. However, the auto-scoring might not work well if the transition in EEG and EMG among each sleep/wake stages is very subtle or not observed.
We have not applied for the medical equipment approval from FDA since we are focusing on supporting researchers who work for basic animal research at the moment. Although SleepSign has more than enough capability to analyze human sleep as well, we prohibit using SleepSign for human analysis at the moment.
SleepSign supports the following sorts of digital data format;
You can select suitable epoch length from the following choices: 4, 8, 12, 5, 10, 15, 20, 30, 60 (sec)
If you differentiate by three stages (Wake, REM, NREM), the average agreement between auto-scoring and your manual scoring will be approximately 90% for Rats. However, if the transition of EEG and EMG between each stages is very subtle or not observed, the auto-scoring may not work properly.
