E. MonitoringPercentSleepforAllActiveChannels(SummaryTab)

The percentage sleep for each channel can be observed at any point during the recording in the

Summary panel shown in Fig. 9. The percentage is based on the sleep threshold and the

histogram formed from the accumulating data. The threshold can be changed during the

experiment, which will change these numbers accordingly. The example shown below is for

noise only channels with sleep percentages all less than 1%. Outliers can be identified here early

in the experiment and can be followed up with direct observation of the mouse or checking the

function of the sensor (e.g. ensure cable is plugged in).

F. CurrentFileInformationandReal‐TimeSettings(Settings/Information

Tab)

After data collection has begun, current information and settings will appear on the

Settings/Information tab shown in Fig. 10. The information in the following text boxes cannot be

changed: Number of active channels, Start Time, File Path, and Active NI-DAQ Device. These

were set earlier when the data acquisition session began. The start time is stored in the data file

header so it is saved with the data to create an absolute time axis for computing statistics related

to the light and dark periods, as well as confirming the date the experiment began. The last line

can be changed and is described below.

Sleep Threshold: The classifier maps features extracted from the signal dynamics related to

sleep to greater (positive) values and those related to wake to lesser (negative) values. Since

these dynamics vary for different mice, the decision statistics will likewise shift depending on

the degree to which the mice follow the average patterns derived from the examples used during

the development of the algorithm . The sleep signal dynamics have less variability than the wake
