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

Communications 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.

High-Density EEG in a Charles Bonnet Syndrome Patient during and without Visual Hallucinations: A Case-Report Study

Cells, 2021
Charles Bonnet syndrome (CBS) is a rare clinical condition characterized by complex visual hallucinations in people with loss of vision. So far, the neurobiological mechanisms underlying the hallucinations remain elusive.

The Curing Coma Campaign: Framing Initial Scientific Challenges—Proceedings of the First Curing Coma Campaign Scientific Advisory Council Meeting

Neurocritical Care, 2020
Coma and disordered consciousness are common manifestations of acute neurological conditions and are among the most pervasive and challenging aspects of treatment in neurocritical care.

Quantifying arousal and awareness in altered states of consciousness using interpretable deep learning

Nature Communications, 2022
The authors propose an explainable consciousness indicator using deep learning to quantify arousal and awareness under sleep, anesthesia, and in patients with disorders of consciousness.

Brain connectivity in pathological and pharmacological coma

Frontiers in Systems Neuroscience, 2010
Recent studies in patients with disorders of consciousness (DOC) tend to support the view that awareness is not related to activity in a single brain region but to thalamo-cortical connectivity in the frontoparietal network.

Needs and Quality of Life of Caregivers of Patients with Prolonged Disorders of Consciousness

Brain Sciences, 2023
Background. Many patients with severe brain damage may survive and remain in a prolonged disorder of consciousness (PDoC), impacting the quality of life (QoL) and needs of their family caregivers.

Transcranial Pulsed-Current Stimulation versus Transcranial Direct Current Stimulation in Patients with Disorders of Consciousness: A Pilot, Sham-Controlled Cross-Over Double-Blind Study

Brain Sciences, 2022
Transcranial direct-current stimulation (tDCS) over the prefrontal cortex can improve signs of consciousness in patients in a minimally conscious state.

Extensive Globular Cluster Systems Associated with Ultra Diffuse Galaxies in the Coma Cluster [PDF]

, 2017
We present Hubble Space Telescope (HST) imaging of two ultra diffuse galaxies (UDGs) with measured stellar velocity dispersions in the Coma cluster. The galaxies, Dragonfly 44 and DFX1, have effective radii of 4.7 kpc and 3.5 kpc and velocity dispersions

Systematically Measuring Ultra-diffuse Galaxies (SMUDGes). I. Survey Description and First Results in the Coma Galaxy Cluster and Environs [PDF]

Astrophysical Journal Supplement Series, 2018
We present a homogeneous catalog of 275 large (effective radius ≳5.″3) ultra-diffuse galaxy (UDG) candidates lying within an ≈290 square degree region surrounding the Coma Cluster.

Cerebral electrometabolic coupling in disordered and normal states of consciousness

Cell Reports, 2023
Summary: We assess cerebral integrity with cortical and subcortical FDG-PET and cortical electroencephalography (EEG) within the mesocircuit model framework in patients with disorders of consciousness (DoCs).
