5、可拆卸的PVDF压电式感应器,附减震软垫。

6、透明亚克力材质鼠笼,顶部带有透气孔,有食物和水的补寄区域,耐高温,可采用80度高温消毒。并且可以根据需求定制。

7、无创实验,无需植入电极,使用非损伤老鼠实验。

8、全自动化的软件,可连续不断地进行数日、数周、甚至数月的实验。

9、软件中可绘制导出老鼠的睡眠/觉醒行为图。

10、可在程序中实时查看每一通道的实时数据。

Mouse System

System modified for use with traditional mouse housing。The PiezoSleep Behavioral Tracking System integrates piezoelectric sensor, data acquisition hardware and soware with custom cages for automated sleep/wake scoring.

Whats New

Non-invasive Alternative to EEG/EMG Sleep Scoring Simultaneous piezoelectric and EEG/EMG data was recorded for twenty-four hours from twenty mice. The EEG/EMG data was independently scored by two trained human scorers and compared against the sleep/wake scores generated by SleepStats. Recall/sensitivity for detection is 91.4% for sleep and 92.3% for wake. Specificity of calls is 91.4% for sleep and 92.3% of wake. SleepStats analysis soware classifies the piezoelectric signal into "Sleep" or "Wake" every 2 seconds. A combination of features, extracted from the piezosignal, are used to classify the data into the two states.System Validation: The classifier was validated by comparing its results against the gold standard method of human sleep scoring of EEG/EMG.
