Loss of consciousness reduces the stability of brain hubs and the heterogeneity of brain dynamics

open access: yesCommunications Biology, 2021
López-González et al study the fMRI brain dynamics and their underlying mechanism from patients that suffered brain injuries leading to a disorder of consciousness as well as from healthy subjects undergoing propofol-induced sedation.

Self-reported changes in sleep patterns and behavior in children and adolescents during COVID-19

open access: yesScientific Reports, 2022
The COVID-19 pandemic and lockdowns worldwide forced children and adolescents to change and adapt their lives to an unprecedented situation. Using an online survey, we investigated whether they showed changes in sleep quality and other related factors ...

Decoding Brain Responses to Names and Voices across Different Vigilance States

open access: yesSensors, 2021
Past research has demonstrated differential responses of the brain during sleep in response especially to variations in paralinguistic properties of auditory stimuli, suggesting they can still be processed “offline”. However, the nature of the underlying

Learning from humans to build social cognition among robots

open access: yesFrontiers in Robotics and AI, 2023
Self-organized groups of robots have generally coordinated their behaviors using quite simple social interactions. Although simple interactions are sufficient for some group behaviors, future research needs to investigate more elaborate forms of ...

From Pulses to Sleep Stages: Towards Optimized Sleep Classification Using Heart-Rate Variability

open access: yesSensors, 2023
More and more people quantify their sleep using wearables and are becoming obsessed in their pursuit of optimal sleep (“orthosomnia”). However, it is criticized that many of these wearables are giving inaccurate feedback and can even lead to negative ...

The Virtual Sleep Lab—A Novel Method for Accurate Four-Class Sleep Staging Using Heart-Rate Variability from Low-Cost Wearables

open access: yesSensors, 2023
Sleep staging based on polysomnography (PSG) performed by human experts is the de facto “gold standard” for the objective measurement of sleep. PSG and manual sleep staging is, however, personnel-intensive and time-consuming and it is thus impractical to

About the Accuracy and Problems of Consumer Devices in the Assessment of Sleep

open access: yesSensors, 2019
Commercial sleep devices and mobile-phone applications for scoring sleep are gaining ground. In order to provide reliable information about the quantity and/or quality of sleep, their performance needs to be assessed against the current gold standard, i ...

Consciousness and cognitive control

open access: yesAdvances in Cognitive Psychology, 2012
The implementation or change of information processing routines, known as cognitive control, is traditionally believed to be closely linked to consciousness. It seems that we exert control over our behavior if we know the reasons for, and consequences of, doing so.

Across the consciousness continuum – from unresponsive wakefulness to sleep

open access: yesFrontiers in Human Neuroscience, 2015
Advances in the development of new paradigms as well as in neuroimaging techniques nowadays enable us to make inferences about the level of consciousness patients with disorders of consciousness (DOC) retain. They moreover allow predicting their probable
