Different features for patient S7. From left to right and then from top to bottom: relative powers of \(\theta\) and \(\beta\), ERR, iCOH, SEF95, LZC and wSMI. The recording lasted for around 24 h: from 15:44 until 15:50 the next day. The shaded areas represent the night time. The different features showed diverging results. For example, a drop/increase between the time frame delimited in red. Higher values of each feature are representative of higher levels of consciousness and inversely. Given the values of the individual features throughout the whole recording, it can be inferred that the patient was certainly conscious all along
