睡眠標記分析軟體

產品型號: Sleepsign
廠牌名稱: Kissei Comtec
在自動判斷上不僅估計睡眠階段,,在這樣的後續檢查的決定和頻率分析,可以輸出一個詳細的分析結果

產品特點

  • 支援客戶進行動物(如大鼠或小鼠)的睡眠分析研究。
  • 能自動判斷睡眠的三個階段(Wake、REM、SWS),能大幅縮短睡眠階段的判定。
  • 可在電腦上長時間記錄來自放大器的模擬訊號。
  • 當有了多種動物的記錄後,可以進行多種動物的數據自動判斷。
  • 藉由規則的睡眠時間階段圖,可以獲得每個階段的發病率及時間,以此量化睡眠的質量。
  • 由於每個分析結果均可以保存成文件檔案,並可以進行2次處理在各種軟體中讀取。

產品規格

1.Waveform Viewer

 

 

1 min/page display
6 hours/page display

 

  • You can select the page length from 4 seconds to 24 hours.
  • Events are displayed on the waveform if events have been inserted by the acquisition program. With the Event Search function, you can jump to an epoch where an event is inserted.
  • An FFT spectrum of the currently selected epoch is displayed on the right bottom of the window (Epoch FFT).

2.Stage Scoring


The auto-scoring function and many useful functions to assist your manual scoring drastically reduce the labor and time you spend on sleep/wake stage scoring.

 

SleepSign scores sleep/wake stages automatically based on EEG and EMG. The criteria of the auto-scoring can be configured flexibly to satisfy various criteria of each researcher. Auto-Scoring results can be manually modified very easily.

NEW FUNCTION !!
Multi animal staging can be simply performed just with one step presetting. You can drastically reduces the time and labor you spend on stage scoring with its Auto-Scoring function.

 

Multi Animal Scoring

 

 

 

1 min/page three rows display
Page divide FFT

You can indicate epochs which contain artifacts as artifact stages automatically or manually. Artifact stages are excluded from the calculation of average FFT, which represents sleep quality, while they are counted for the Stage Graph and the Vigilance State Parameters, which represent sleep quantity. An asterisk is displayed above the stage name if the epoch is indicated as an artifact stage.

  1. Auto-Scoring
  2. Manual-Scoring
    • You can manually score sleep/wake stages quite easily by using a mouse or a keypad.
    • Three or five rows of pages can be displayed, and scored at a time.
    • You can display FFT spectrums of each epoch in a page (Page divide FFT). You can refer to these FFT spectrums when you score sleep/wake stages.
    • You can list epochs which satisfy criteria of multiple stages of auto-scoring. This function helps you to review and modify the subtle part of auto-scoring results.

  3. Epoch length can be selected among the following: 4, 5, 8, 10, 12, 20, 30, 60 seconds. You can select suitable stage classification for your purpose from pre-assigned stages (Wake, REM, NREM, Light, Deep, etc.) and up to three un-assigned stages.

3.Hypnogram/Trend Graph

 

 

The stage scoring result is displayed as the Hypnogram. In addition, various sorts of information can be displayed as Trend Graphs on the same time scale as the Hypnogram. The sorts of Tend Graphs are as follows;
  • FFT analysis result
  • Percentage or frequency of a prticular waveform (such as Delta, Theta, Spindle) per epoch.
  • EMG integral
  • Maximum or mnimum value in an epoch (useful for plotting parameters such as temperature, blood pressure).
  • Many other parameters

*you import data files of DSI Dataquest A.R.T system, you can display parameters saved in the parameter file (such as activity, temperature, heart rate) as Trend Graphs.

You can print the Hypnogram and Trend Graphs as well as save it as a text file or a bitmap file.


4.Stage Graph

 

 

SleepSign calculates the total duration or percentage of each sleep/wake stage by any time bin and time range, and draws the Stage Graph. You can print the Stage graph as well as save it as a text file or a bitmap file.

 


5.Vigilance State Parameters

 

 

SleepSign displays a time series list of each episode (a series of sleep/wake stages) along with duration of each episode. In addition, frequency, mean duration, and standard deviation of each episode are displayed. You can calculate and display Vigilance State Parameters by any time bin and time range (ex: light period vs. dark period, or every 6 hours). With this function, you can grasp the transition of sleep/wake patterns easily.

 

 

You can save the Vigilance State parameters result in a text file.

 

 

You can also obtain the frequency of each episode sorted by duration

 


6.Average FFT


SleepSign calculates average FFT spectrums of each sleep/wake stage by each time bin and time range. The result can be saved as a text file. The average FFT spectrum is referred to as an index of sleep quality by comparing them by units or different periods of time (ex: light period vs. dark period, sleep deprived vs. control).

 

Average FFT of NREM and REM in light period and dark period

 


7.Other functions

 

  • Digital filter

  • You can apply low path filter, high path filter, band path filter, band stop filter, or smoothing to each channel.
  • Save as a bitmap file

  • You can save the following images as a bitmap file: Whole window, waveform, Hypnogram/Trend Graph, Stage Graph, etc.
  • Print

  • You can print the following images: waveform, Hypnogram/Trend Graph, Stage Graph
  • Save as a text file

  • You can save the following values as a text file: raw data, Hypnogram/Trend Graph, FFT result, Vigilance State Parameters, Stage Graph, etc.
    - You can print auto-scoring parameters or save them as a text file.
