Description
Summary:Microsleeps, the seconds-long interruptions of wakefulness by eye closure and sleep-related brain activity, are dangerous when driving and might be too short to provide the restorative functions of sleep. If microsleeps fulfill sleep functions, then animals faced with a continuous need for vigilance might resort to this sleep strategy. We investigated electroencephalographically-defined sleep in wild chinstrap penguins at sea and while nesting in Antarctica constantly exposed to an egg predator and aggression from other penguins. The penguins nodded off >10,000 times per day, engaging in bouts of bihemispheric and unihemispheric slow-wave sleep lasting on average only 4 s, but resulting in the accumulation of over 11 h of sleep for each hemisphere. The investment in microsleeps by successfully breeding penguins suggests that the benefits of sleep can accrue incrementally. This repository contains raw electrophysiological data (Electroencephalography and electromygraphy) with identified accelerometry, ... : The electrophysiology data could be opened on any scientific software that could opened interlaced 16bits binary data. The video could be run with any videoplayer. the CSV and xls file could be opened with adapted software our .exp file could be opened with a text editor like notepad++ The sleep event are provided in a mat file which could be opened in matlab (Mathworks) The analysis pipeline was writen in matlab R2020 (associated with signal processing and image processing toolbox and chronux, http://chronux.org/). Our scripts are provided with our exptoolbox build to read and process easily our data. ...
